An innovative Fault Pattern Detection Methodology has been carried out using a combination of Machine Learning Techniques to produce a seismic volume suitable for fault interpretation in a structurally and stratigraphic complex field.
Through theory and results, the main objective was to demonstrate that a combination of ML tools can generate superior results in comparison with traditional attribute extraction and data manipulation through conventional algorithms.
The ML technologies applied are a supervised , deep learning, fault classification followed by an unsupervised, multi-attribute classification combining fault probability and instantaneous attributes.
The results are encouraging showing a higher level of structural details when compared with other interpretation techniques. Furthermore, visualization enhancement to better define stratigraphic relationships has also been partially achieved by the combination of fault probability volumes obtained from ML CNN fault detection procedure and multi-attribute classification of seismic features or SOM (Self Organizing Maps).
Machine Learning Technology was applied to a reprocessed seismic dataset in depth domain to generate a detailed, robust and reliable seismic fault attribute volume. The results are being used to constructing a more confident structural framework in the area and better understand stratigraphic trends and relationships to serve as input for static modeling.

Offset wells proximal to new hydraulically fractured wells often see intense pressure spikes that can damage the structure of the well, promote sand production and/or impact post-completion production. To mitigate these impacts, operators may shut in all offset wells within a radius of the new completion. Determination of the shut-in radius is often based on analogous operations and experience alone, and tends to be conservatively derived, potentially leading to the unnecessary shut-in of wells that may otherwise not experience any pressure event. Shutting-in too many wells can be the largest expense incurred by a new completion as operators not only work-over the offset wells, but also lose production for the entirety of the completion job. On the other hand, an underestimated shut-in radius might enhance fracture-driven interference during a completion job. An analytics and machine learning approach is presented to better understand the area of concern for offset wells and provide a data-driven recommendation for shut-in radius. The approach has been applied to a large field data set and indicates that historical data can be used to quantify the zone of communication and provide recommendations for future operations.

Upstream processes for the petroleum industry are now data-driven. Throughout the history of exploration and production in unconventional environments, multidisciplinary engineering and geoscience data have been continuously collected. Now, using machine learning and AI, this data is being used in new ways to address fracture stimulation and frac-driven interference by enhancing frac modeling. Through the use of data-driven machine learning techniques, models and frameworks can be tailored to individual assets of interest to predict and analyze frac stimulation within a reservoir. However, it seems the data available is still not enough to accurately predict frac behavior.
This presentation will focus on fluid tracking using an electromagnetic technique that provides the missing link to improve machine learning frameworks for frac modeling without disrupting existing workflows. This data directly correlates to completions and production data by providing direct measurements taken during frac stages, which in turn generates relevant features for machine learning inputs. An outlook is also given on recent developments in real time fluid tracking and how it can be integrated with AI to prevent frac-driven interference and forecast performance on a per-stage and per-well basis.

The process of statistically analyzing multiple seismic attributes using a SOM (Self-Organized Map) algorithm has been around for several decades. However, advances in computing power, coupled with the many new attributes developed in the last 30 years, has made this type of analysis extremely powerful.
In the past, SOM has been used on only one attribute at a time using the seismic wavelet as the basis for the neural analysis. The approach in this presentation is using SOM on multiple seismic attributes at one time, and in a sample-based, not wavelet, format.
Studies done in the Meramec Formation in Central Oklahoma and the Woodbine Formation of East Texas will be highlighted for the SOM process’s ability to find the best reservoir through the statistical analysis of seismic attributes. Then, converting the neural clusters into Geobodies, calculations can be made to determine reservoir size and reserve estimates. A statistical tool is also embodied to show how the neural patterns can be compared to distinct petrophysical rock properties to confirm the presence of the reservoir.

Sr Field is a gas field located 100 km offshore west Nile Delta, within the West Delta Deep Marine (WDDM) concession of Shell (Rashid/ El-Burullus joint venture). The water depth ranging from 500-1000 meters.
The Field was penetrated by 4 wells, two of them are exploration wells (So-1 & Sr-1) and the other two are development wells (Sr-a & Sir-c). It is a stratigraphic Pliocene channel of 35-40 km length and 500- 100-meter width, with a clastic sand reservoir of 100-200 meter thickness. The filed is covered by 3D seismic of good quality. One segment of this channel has about 0.65 TCF of gases and three wells from the four wells are included at this segment.
The channel was conventionally mapped using Hampson Russel Spectral decomposition. Unsupervised machine learning is recently used for clustering the data and isolate the channel using the Paradise® software from Geophysical Insights.
Spectral magnitude, spectral voice, spectral phase, sweetness, energy ratio similarity, and Envelop are were identified by Principal Component Analysis (PCA) as having the highest energy in the region of interest. These attributes were then classified simultaneously over the reservoir zone using the Self Organizing Map (SOM) application, a form of machine learning.
Application of the unsupervised Machine learning using SOM clearly demonstrate the strike and geomorphology of the Pliocene marine turbidities. The southern segment of the channel penetrated with the three wells are very well defined after posting the wells. No significant difference on the neurons (hexagons) at the locations of the three wells which reflects the similarity of reservoir nature, thickness, sand content and pay thickness. A significant other channel is resolved to the east of the main channel that is not detected using the conventional spectral decomposition.

Frac hits are a form of fracture-driven interference that occurs when newly drilled wells communicate with existing wells during a completion job. In most cases, frac hits leave a negative production impact. Understanding the main causes of frac hits is complicated and at the same time crucial for optimizing the net profit value of a well pad. Frac hits happen due to a combination of different parameters such as depletion and stress history, inter-well spacing, completion design, and rock characteristics. The available physics-based diagnostics workflows produce outputs with a high degree of uncertainty. These approaches also are unable to handle a database beyond a single well or a few stages. We developed a data-driven approach based on the pattern recognition capabilities of machine learning techniques to characterize and aid understanding of the root causes of frac hits in a well pad during a completion job. The approach was applied to a field data set and indicated that frac hits can be quantitatively attributed to operational or subsurface parameters such as spacing or depletion. A better understanding of frac hits will help to optimize well spacing and completion design parameters and consequently improve hydrocarbon recovery and maximize the return on capital investment.

Most O&G technicians have one day or another received a core analysis report, a geochemistry report, a pressure-volume-temperature report with several pages of tabulated values with no other choice but to retype the values in Excel to make them usable. This issue not only occurs in the subsurface domain but in all of the O&G sector as well as in other industries. With the support of TOTAL, Technip, Saipem, Schlumberger, Subsea7 and IFPen, Agile Data Decisions has developed an open source solution to automate the extraction of tabular data from documents. This solution combines probabilistic modeling of sequences with machine learning to detect and segment the tables. The approach is very similar to the human approach: A reader can localize a table in a page by looking at the text alignment, the spacing between strings, the ratio between numerical and letters, etc. All of these features are captured by machine learning and deep learning methods for training and detection of tabular data in this project. As required by our sponsors the technology will be released to an open source platform in October 2020 under MIT license for the benefit of the Data Management community. The presentation will describe the novel machine learning approach and provide examples of table automatic detection and segmentation.

Seismic fault detection is one of the critical steps in seismic interpretation. Identifying faults is crucial for characterizing and finding the potential oil and gas reservoirs. Machine learning holds promise for eliminating some of the tedious and repetitive steps in fault interpretation. Seismic amplitude data serves as input for automatic fault detection and deep learning Convolutional Neural Networks (CNN) perform well on fault detection without any human interactive work. This presentation shows an integrated CNN-based fault detection workflow which enhances the final fault detection volume by applying pre and post processing and an unsupervised seismic classification to ultimately isolate faults within a 3D volume. The pre and post processing objectives were to suppress noise or stratigraphic anomalies subparallel to reflector dip and to sharpen fault and other discontinuities that cut reflectors. To suppress cross-cutting noise as well as sharpen fault edges, a principal component edge-preserving structure-oriented filter is first applied. The conditioned amplitude volume is then fed to a pre-trained 3D synthetic CNN model to compute fault probability. Finally, a 3D Laplacian of Gaussian filter is applied to the CNN fault probability to enhance fault images. The resulting fault detection volumes (fault probability, fault dip magnitude and fault dip azimuth) compare favorably with traditional human interpretation and in complex structural settings, provide a more complete and unbiased image of faults. Finally, the fault volume is input into an unsupervised machine learning seismic classification (SOM) to generate a 3D volume in which the faults volumes are classified into discrete neurons with known values. This provides superior final results which can subsequently be used to generate geobodies of individual faults or used directly as input to other fault surface extraction tools.
Jie Qi received a Ph. D. (2017) in geophysics from the University of Oklahoma, Norman. He was a postdoctoral research associate at University of Oklahoma from 2017 to 2020. He is currently a research geophysicist at Geophysical Insights. His research interests include machine learning-based seismic interpretation, pattern recognition, image processing, seismic attribute development and interpretation, and seismic facies analysis.
Interpreters face two main challenges in computer-assisted seismic facies analysis. The first challenge is to define, or “label”, the facies of interest. The second challenge is to select a suite of attributes that can differentiate target facies from each other and from the background reflectivity. Accurately defining the seismic expression of a given seismic facies requires an understanding of not only geologic processes but also the limits of seismic acquisition, processing, and imaging. Our goals are to provide a good classification model in terms of validation accuracy, provide quantitative metrics (and ideally, geological insight) as to why a given attribute suite is chosen, and to minimize the computational and memory required.
In principle, a desirable attribute subset is built by detecting relevant and discarding irrelevant attributes. Relevant attributes are those that are highly correlated with the output classes using a technique called univariate attribute analysis. In contrast, redundant attributes are highly correlated with each other. We hypothesize that the redundant and useless attributes that confuse human interpreters also pose problems in machine-learning classification.

Quantitative seismic reservoir characterization poses a mathematically ill-constrained inversion problem traditionally solved by methods relying on pre-stack seismic inversion and subsequent rock physics transforms. Alternatively, subsurface models can be matched to field seismic data by seismic forward modeling using wells as calibration points. Both these approaches face practical limitations in the sparsity of calibration data and severe non-linearity of the problem requiring multiple simplifying assumptions. Recent extensive developments in machine learning and data-driven model building can provide significant accuracy and efficiency uplift in solving this problem by streamlining seismic attribute analysis and avoiding the need to pass through the elastic domain. We present various approaches to seismic machine learning and their application to both static and dynamic reservoir characterization projects and discuss comparisons to conventional 3D and 4D quantitative interpretation workflows. Emphasis will be given to practical approaches enhancing cross-discipline integration and validation of data analytics methods using both geophysical and data science approaches. We highlight the advantages, challenges and systematic biases encountered in this type of analysis and discuss potential extensions of the data analytics approach using deep learning methods.

Today most of the focus of AI on the Machine Learning / Deep Learning industry requires a large amount of data that is not always available in early phases of Exploration and Production. To address the data restrictions, I will discuss neuro-symbolic approaches to combine Machine Learning / Deep Learning with formal pre-existing domain knowledge and formal knowledge representation and reasoning. This knowledge-enhanced Machine Learning approach, coupled with transfer learning techniques, allows working with a smaller amount of data and effort necessary to train AI-based models. We will discuss how we can augment ML technologies with domain and contextual knowledge, and enabled more effective transfer learning in applications to real cases for AI-assisted seismic Interpretation and well-log analysis.

The progress is enabled by technology gains in powerful computing infrastructure, deep learning algorithms and models, and more importantly the understanding learned at the interface between and integration of subject matter knowledge and machine learning/AI techniques. The diversity and complexity of many applications in the industry involving data from wide range of time-spatial scales and measurement modality also pose interesting research challenges for machine learning.
In this talk, I will share a number of examples for machine learning in upstream applications, including the generalizability and risk of overfitting in deep learning based geophysical inversion, integrating surrogate physics constraints in machine learning based coherent seismic noise removal, cross-modality machine learning in quantitative microscale characterization, and fiber optic DAS based hydraulic fracturing monitoring using deep learning. While the results from these examples are encouraging, the goal is to highlight the challenges and opportunities for machine learning/AI research and development in upstream applications.

The past a few years mark the fastest development of machine learning in seismic interpretation community we have ever seen. One of the major accelerators of such growth is the success of deep learning methods, originated from the computer vision discipline. Over the past three years, we witnessed the rapid adoption of deep learning techniques in seismic interpretation. However, most of such adoption is still limited to academia and research institutes, primarily due to the fact that, albeit providing a high-quality result, deep learning methods usually requires much more training data to work effectively. Preparing such training data is often time-consuming, if not impractical, for a seismic interpreter. This presentation is focused on deep learning applications that require limited or even no training data from a general seismic interpreter, which make deep learning more accessible to general seismic interpreters. Examples on deep learning-based seismic facies classification and fault detections demonstrate that a general seismic interpreter can benefit from the high-quality result, while also with greatly improved efficiency.

Despite its time-honored use of technologies, the upstream oil and gas sector has been slower than other industries to embrace the breakthrough solutions that have transformed several sectors over the past decades. That may be about to change. Much has happened and COVID-19 has had multiple impacts on the oil and gas industry including plunged prices and government revenues, significantly lowered demand, and inflated stockpiles of crude oil. As the industry seeks ways to return to profitability, Next-Generation technologies are emerging as a part of the answer, presenting the possibility of a radically more efficient new reality.
The development of Next-Generation technologies has the potential to transform the upstream oil and gas industry’s fortune by sustainably improving exploration portfolio, capital efficiency, lowering exploration and development costs, and reducing time to first oil. These new technologies bring significant changes to an upstream oil industry’s ecosystem, disrupting the traditional value chain and redefining business models. We took a Next-Generation Technology Stack Lens approach to explore how these breakthrough solutions will alter the upstream industry eco-system by examining Digital Programs, Workflow efficiency and Innovative Projects. This breakthrough approach offers the structure that the upstream industry needs to understand Next-Generation Technologies.
To this end, this presentation will dive deep into PETRONAS’s NexTGEN Technology plan for exploration that is converting data to insights and taking actions based on those insights. We believe that the process of NexTGEN will be unique to each step because upstream exploration contains a discrete set of technologies such as Machine Learning, Data Analytics, and Cloud-based Solutions for a distinct flow of data, a particular set of challenges, different digital maturity, and nature of data generated and utilized in each step differs from that others. NexTGEN is set to have a profound impact on PETRONAS’ exploration delivery mandates. A wave of Next-Generation Technologies is bringing greater technological innovation that powers value creation in Oil and Gas.
The paper describes the combined use of machine learning and statistics to correlate to reservoir properties, thereby discriminating between the presence or absence of a reservoir. The results, presented using multiple statistical techniques, are repeatable and dependable in positive reservoir identification, including the reservoir's extent.
The first stage of the proposed statistical method has proven to be very useful in testing whether or not there is a relationship between two qualitative variables (nominal or ordinal) or categorical quantitative variables in the fields of health and social sciences. Its application in the oil industry allows geoscientists not only to test dependence between discrete variables but to measure their degree of correlation (weak, moderate or strong). The talk shows its application to reveal the relationship between a SOM classification volume of a set of nine seismic attributes (whose vertical sampling interval is three meters) and different well data (sedimentary facies, Net Reservoir, and effective porosity grouped by ranges). The data were prepared to construct the contingency tables, where the dependent (response) variable and independent (explanatory) variable were defined, the observed frequencies were obtained, and the frequencies that would be expected if the variables were independent were calculated, and then the difference between the two magnitudes was studied using the contrast statistic called Chi-Square. The second stage implies the calibration of the SOM volume extracted along the wellbore path through statistical analysis of the petrophysical properties VCL and PHIE, and SW for each neuron, which allowed to identify the neurons with the best petrophysical values in a carbonate reservoir.

There is much hype around all topics related to digitalization and IR 4.0 and their underlying technologies. At the same time, industries have already seen some real-life applications and benefits as well as some real disruption to their value chains, making it more urgent than ever for oil & gas companies to accelerate their digital transformations. Despite the hype and the promise of machine learning, adoption outside of the tech sector is still at an early, often experimental stage with few firms having deployed it at scale.
This presentation will discuss some of the successes and challenges of moving machine learning in Oil & Gas from hype to reality. There have been plenty of promising successful deployments across robotics and autonomous vehicles, computer vision, virtual agents, and machine learning, with the latter including deep learning and underpinning many recent advances in the other AI technologies. However, the fact that it requires big data that must be trained on what’s often sparse, incomplete, and messy data, its tendency to cut across functional, geographic, and organizational silos, and its dependence on having a digital foundation and an upskilled workforce pose formidable challenges to scaling digital and machine learning in particular.

Compressor stations used to move natural gas are one of the largest sources of fugitive methane emissions in the midstream sector, accounting for approximately 50% of all fugitive emissions(Zimmerle et al., 2015). This problem is most widespread at reciprocating compressors (Subramanian et al., 2015) where faulty seals are a key contributor to methane emissions (Johnson et al., 2015). As such, there is a significant need for a robust technology that could provide an early indication of an unexpected emission. Equally important, the technology needs to be able to account for biogenic versus anthropogenic sources of methane. One means of indirectly making this determination is to leverage optical technologies that can autonomously pinpoint the source of such leaks.
This presentation discusses recent work funded by the U.S. Department of Energy (DOE) National Energy Technology Laboratory (NETL), focused on the development of an innovative remote sensing technology that can reliably and autonomously detect fugitive methane emissions in near real-time, using computer vision and deep learning. The technology called the Smart Methane Leak Detection (SLED/M) system was initially developed to monitor facilities such as compressor stations in a stationary, pan-tilt-zoom configuration.
The system has recently been adapted to monitor facilities from an unmanned aerial system (UAS). The speed and maneuverability of UAS platforms are attractive to leak detection and repair program operators but introduce several challenges. Many existing methane detection algorithms rely on mostly static backgrounds becoming unusable with motion. In addition, top-down views of fugitive methane emissions present differently in Optical Gas Imagers (OGI) compared to looking across the plume. Our work has focused on overcoming these challenges, enhancing the operators' ability to detect methane emissions and pinpoint their sources. Another recent adaptation to SLED/M is the ability to quantify methane emissions using passive sensors (OGI, thermal camera), environmental conditions, plume modeling, and deep learning.
SLED/M advances the state-of-the-art for methane emission detection and quantification by focusing on three key critical criteria for effective methane emission mitigation: (1) autonomy (no need for a human to be in the loop), (2) high reliability (low false alarm rates), and (3) real-time performance. Results from this work will be presented.

Every day our lives are intertwined with applications, services, orders, products, research, and objects that are incorporated, produced, or effected in some way by Artificial Intelligence and Machine Learning. Buzz words like Deep Learning, Big Data, Supervised and Unsupervised Learning are employed routinely to describe Machine Learning, but how do these applications relate to geoscience interpretation and finding oil and gas? More importantly, do these Machine Learning methods produce better results than conventional interpretation approaches? This course will initially wade through the vernacular of Machine Learning and Data Science as it relates to the geoscientist. An overview of how these methods are being employed, as well as, interpretation case studies of different machine learning applications will be presented. An overview of how high-performance computing and the utilization of Cloud Services related to Machine Learning will be described. Machine Learning is a disruptive technology that holds great promise and this course will be presented from an interpreter’s perspective, not a data scientist. This course will provide an understanding of how Machine Learning for interpretation is being utilized today and provide insights on future directions and trends.

Mapping and extracting features of interest is one of the most important objectives in seismic data interpretation. Due to the complexity of seismic data, geologic features identified by interpreters on seismic data using visualization techniques are often challenging to extract. With the rapid development in GPU computing power and the success obtained in computer vision, deep learning techniques, represented by convolutional neural networks (CNN), start to entice seismic interpreters in various applications. The main advantages of CNN over other supervised machine learning methods are its spatial awareness and automatic attribute extraction. The high flexibility in CNN architecture enables researchers to design different CNN models to identify different features of interest.

Time-lapse (4D) seismic analysis plays a vital role in reservoir management and reservoir simulation model updates. However, 4D seismic data are subject to interference and tuning effects. Being able to resolve and monitor thin reservoirs of different quality can aid in optimizing infill drilling or locating bypassed hydrocarbons. Using 4D seismic data from the Maui field in the offshore Taranaki basin of New Zealand, we generate typical seismic attributes sensitive to reservoir thickness and rock properties. We find that spectral instantaneous attributes extracted from time-lapse seismic data illuminate more detailed reservoir features compared to those same attributes computed on broadband seismic data. We develop an unsupervised machine learning workflow that enables us to combine eight spectral instantaneous seismic attributes into single classification volumes for the baseline and monitor surveys using self-organizing maps (SOM). Changes in the SOM natural clusters between the baseline and monitor surveys suggest production-related changes that are caused primarily by water replacing gas as the reservoir is being swept under a strong water drive. The classification volumes also facilitate monitoring water saturation changes within thin reservoirs (ranging from very good to poor quality) as well as illuminating thin baffles. Thus, these SOM classification volumes show internal reservoir heterogeneity that can be incorporated into reservoir simulation models. Using meaningful SOM clusters, geobodies are generated for the baseline and monitor SOM classifications. The recoverable gas reserves for those geobodies are then computed and compared to production data. The SOM classifications of the Maui 4D seismic data seems to be sensitive to water saturation change and subtle pressure depletions due to gas production under a strong water drive.

Machine learning has evolved over several decades. Since the mid-2000s, neural networks have re-emerged along with various deep learning architectures. These advances have enabled successful applications of deep learning methods in many industries. However, these methods are not being fully exploited in the Oil and Gas industry. Today, many researchers and engineers have taken the initiative to actively research and develop numerous modern machine learning applications in various domains in this industry, including geosciences, drilling, field development planning, completions, production forecasting, to name a few. During the talk, I will demystify the Machine Learning journey and share examples of how machine learning is changing our industry for the years to come. I will share lessons learned from our own company’s experience in this domain.
Data – its availability, volume, and diversity, along with advances in machine learning and computational power, have created unique opportunities to not only achieve significant improvements in both our and our clients, performance, but also to transform how the oil and gas service industry operates today, and in the future.

3D seismic imaging revolutionized hydrocarbon exploration providing a robust picture of the subsurface. Higher prices enabled expensive technologies and investments in the development of previously uneconomic deposits. The balance between development and the market value of the gas or oil is critical. Recent advances in 3D seismic allow interpreters to map areas of higher productivity and identify bypassed reserves. MicroSeismic mapping has made completion more efﬁcient and safer. Geophysical data is now an accepted early development tool of successful oil and gas companies.

Over the last decade, the O&G Energy industry has slowly evolved to incorporate essential digitalization components from the so-called “Industry 4.0 Revolution”. Nevertheless, this digitalization process has led to an explosive increase in the magnitude and value of data generated from several interconnected systems, each with their proprietary framework, standards, and analytical platforms that leave the engineers in charge of critical decision making overwhelmed by the amount of endless segregated information flow. Companies are required to break an ongoing project into small individual tasks and develop the required digital interfaces between every single moving subsystem in-house. This leads to unnecessary complexity, lack of long-term support, and inefficiencies. Furthermore, progress is still lacking in artificial intelligence, visualization, and interoperability of the drilling/energy/business processes.
This presentation will focus on how we aim to solve these problems by developing a state-of-the-art energy analytics and visualization digital twin platform that leverages photorealistic real-time graphics, high-fidelity numerical simulation, and trained physics-based machine learning algorithms to provide the entire energy extraction processes at the fingertips of the operator through a revolutionizing cloud-based platform.

Traditional interpretation approaches that geologists and geophysicists employ are physics-based solutions and now Machine Learning threatens to alter that accepted practice. Will the integration of machine learning improve our present interpretation workflows, provide moderate to no improvements (overhyped) or produce “profound” results that have not been identified previously? Machine Learning is a disruptive technology that holds great promise and this presentation will explore that potential from a geoscience interpreter’s perspective.

Different tech industries in silicon valley were successfully able to reap the benefits of integrating machine learning into their business models. The oil and gas industry is slowly but surely catching up to the trend of utilizing machine learning in different aspects of the business. Several oil companies and service providers have partnered with tech companies like Microsoft and others to reap the benefits of data analytics for their organizations. In this talk, I will briefly touch upon different applications of data analytics possible in reservoir engineering and how some of the recent work done in this space have benefited the reservoir engineering community with reduced cycle times. Finding the right models to fit your data is of extreme importance and all engineers need to step up and get digitally fluent to be able to leverage data science into mainstream workflows fully. Traditional reservoir engineering workflows are time and labor-intensive. Integrating multiple sources and scale of data coming in from a variety of surveillance operations need an integrated approach to characterize reservoirs quickly and accurately. Three case studies will be presented from published literature that have presented new ways of using machine learning techniques to improve reservoir simulation, reserves forecasting and reservoir monitoring.

The evaluation of seismic attributes is a powerful tool in the interpretation of different geologic environments of deposition. Seismic attributes, specifically geometric and spectral decomposition attributes, provide a framework for interpreting geologic features that define depositional environments. This video course identifies the appropriate seismic attributes for various geologic settings and describes how these attributes are applied. Lecture and demonstrations cover the use of attributes in interpretation workflows and manipulate attribute parameters to highlight geologic features. The last video segment of the course describes how sets of attributes are analyzed and classified using multi-attribute, Machine Learning processes to extract more information from the seismic response.

A multidisciplinary approach that is maximizing information extraction from seismic to predict lithofacies and reservoir properties, based on the following steps is presented:
Multi-attribute seismic analysis was applied based on an unsupervised machine learning process called Self- Organizing Maps (SOMs) in Paradise software. The selection of input attributes was thoroughly tested and optimized, based on close co-operation between geophysicists and geologists to extract more extensive and detailed geological features from seismic.
Using the information from nearby wells and knowledge of rock physics, the individual neural classes were quantified and validated and then reorganized and translated to formation properties such as lithofacies, porosity, and clay content.
The study focused on the benefits and additional information that can be gained with this new approach compared to traditional quantitative interpretation approaches (i.e., a prediction from acoustic impedance alone). Multi-attribute classification using machine learning, SOM, gave a better representation of seismic characters, detecting the geologic trends in the field. A detailed quantitative interpretation of SOM neural classes was established to validate and translate formation-related classes optimally for reservoir prediction, and to eliminate classes irrelevant to the formations (i.e., seismic noise).
The result from the Wisting case study shows that the new method gives the best match to the well data and extracts more reservoir related information from seismic compared to the conventional quantitative interpretation (QI) approach. In the upper part of the Triassic, with fluvial sediments assigned to the RG2 unit (Fruholmen Fm.), the reservoir quality and extent of mud clast rich channel intervals are debated. In two of the wells (E and B), a thicker mud unit was observed, and it was debated if this could act as a barrier towards the overlying good reservoir. The result shows that the mud intervals are deposited locally and do not represent a regional mud layer. The additional information from seismic seems to be valuable when used as input and refinement to the digital geological model.

The promise of Machine Learning applications in oil and gas is well-known, with most of the sector some way along the journey – particularly upstream. But the journey is not straightforward, with plenty of cautionary tales about high costs, low uptake, and dashed expectations.
Defining the right problem – and then developing the right solution - requires strong partnerships with technology companies and academia. Sophisticated and semi-automated data science tools are becoming increasingly accessible to technical staff, but the complementary skillsets of the data science discipline are vital to avoid common pitfalls like overtraining and poor data quality.

Machine learning has been used over several decades in applied geoscience within the energy industry. Machine learning and deep learning can provide a clearer and faster understanding of the reservoirs with more efficient data analysis and integration. Artificial intelligence evolved with the development of sophisticated techniques and software. Additionally, powerful CPUs/GPUs allow complex algorithms to increase their prediction power and reduce both uncertainties and running time. Lately, innovative learning algorithms allow computers to re learn from their own predictions.
With artificial intelligence, geoscientists are capable to make reliable and faster prognosis based on existing logs, seismic, core to support the numerous requirements at the different scales of the subsurface, from frontier exploration to development projects. Besides, geoscientists demand a searchable, organized, diverse, validated, and unique database for all data types, with historical and current data, to generate new play concepts for conventional and unconventional reservoirs in onshore and offshore basins.
During my talk, I will reinforce the opportunities that innovation and diversity have for artificial intelligence success in applied geoscience, for prediction, uncertainty management and efficiency in the years to come.
