Petrolern At-home Seminar Series – P.A.S.S

April to July 2020
Price: Free


In accordance with its knowledge transfer mission, Petrolern LLC conducted a series of 29 free online seminars with the objective to keep the subsurface community learning and motivated during the downtime with COVID-19 and the low oil price. The program, which started in April 2020 and ended in July 2020, included two technical presentations every week given by industry leaders and academic professors in oil and gas, geothermal energy and carbon storage spaces. The program was extremely successful with nearly 750 attendees from 80 countries. The program presented 13 talks on topics related to the oil and gas technology and applications, 7 talks on carbon storage, 4 talks on geothermal energy, and 5 talks on other general topics related to the subsurface community. We express our sincere gratitude to all the distinguished presenters who came from industry, academia, government agencies, and AAPG leadership.

Field Development Geomechanics

Will be announced soon
Price: TBA

Course Description: Geomechanics is an essential component of production from both conventional and unconventional reservoirs. Integrity of the wellbore plays an important role in all oil and gas operations including drilling, completion, stimulation and production. Borehole failure, stuck pipe/tool, mud losses, casing collapse, compaction, subsidence, permeability reduction, sanding, and requirement for stimulation cost the oil and gas industry several billions of dollars annually. Minimizing the cost of these issues requires clear understanding of the interaction between formation properties, in‐situ stresses, and our operations. Geomechanics also provide valuable information about reservoir performance during production and can help to optimize reservoir management strategies. 

This multi-disciplinary course provides a concise overview of basic rock mechanics and its application in many practical problems encountered at well and field scales. It presents the history and importance of geomechanics in oil and gas industry and explains required theoretical rock mechanics background. In addition, you will learn how to use geology and drilling information, well logs and core data from off-set wells to construct 1D to 3D geomechanical models. You will also learn how to calibrate the model with previous drilling experiences. The second part of this module reviews different applications of geomechanics in field development from exploration to abandonment. Applications such as wellbore stability for generic and optimum well trajectories, hydraulic and acid fracturing stimulation, production optimization from natural fractures, and reservoir compaction and subsidence. The pros and cons of 1D and 3D models for each application will be discussed.


Hydraulic Fracturing Design and Execution

Will be announced soon

Price: TBA

Course Description: This class introduces the basic characteristics and theories surrounding hydraulic fracturing and the main process of fracturing in shale, including the main workflow, the details in case analysis, and the fundamental differences between theory, study, and practical operation. The course takes the complex nature of the hydraulic fracturing in unconventional reservoirs and applies a practical approach that can be used as a workflow for designing fracture treatments in various shale basins across the world. Providing the audience with theories, best practices, operation and execution, and economic analysis of hydraulic fracturing in unconventional reservoirs, this course guides the engineer and manager through broad topics including an introduction to unconventional reservoirs, shale reservoir characterization and parameters for production enhancement, and shale gas in place calculation as well as expanding to basic theories of hydraulic fracturing and advanced topics in shale reservoir stimulation. Rounding out with coverage on the environmental aspects and practice problems on design and economic analysis, this course delivers the critical link needed between academia and industry for all aspects of hydraulic fracturing operations.


Unconventional Resource Assessment and Valuation

Will be announced soon
Price: TBA

Course Description: The remarkable growth of unconventional resources in North America has already changed the global energy landscape. There are multiple sources of uncertainty in unconventional plays. Some uncertainty is due to the extremely small pore size and low permeability of many of these reservoirs and the difficulty in obtaining accurate measurements of porosity and saturation. Other sources of risk involve development strategies, infrastructure and commercial uncertainty. Therefore, it is imperative that geoscientists and engineers who are working on unconventional projects have a clear understanding of what is involved in systematic and accurate evaluation and assessment of unconventional resources to set a stage for their profitable development. This is an intensive and interactive course focusing on Assessment and Valuation of Unconventional Resources. The course starts with a brief overview of the current status, future potential and different categories of unconventional resources. After the brief overview, fundamental technical concepts involved in exploration, assessment, development of unconventional resources (from geology to well completions) are covered to set the stage for main subject of the course. The course presents in some detail industry standard and widely used methodology by major North American operators for systematic assessment of unconventional resources accounting for their unique characteristics and higher level of inherent uncertainty. Also covered in the course are specific methodologies for assessment and evaluation of shale gas, tight gas, tight/shale oil and CBM resources. After attending this course, a participant is expected have acquired skills required to explore, assess and evaluate an unconventional resource project with a view to determine commercial viability and profitability of the proposed project by undertaking screening economics.


Hydraulic Fracturing and Machine Learning for Oil and Gas Applications

Will be announced soon

Price: TBA

Course Description: This class is presented in two modules: Hydraulic Fracturing and Machine Learning. The first module introduces the basic characteristics and theories surrounding hydraulic fracturing and the main process of fracturing in shale, including the main workflow, the details in case analysis, and the fundamental differences between theory, study, and practical operation. The course takes the complex nature of the hydraulic fracturing in unconventional reservoirs and applies a practical approach that can be used as a workflow for designing fracture treatments in various shale basins across the world. The second module discusses the applications of artificial intelligence and machine learning  in the oil and gas industry. The course uniquely describes theories and practical applications to easily follow, digest, understand, and apply. It will have a combination of applying various machine learning models to different practical applications using Python which is a free open source programming language. This course will focus more on understanding the basic concept of each algorithm, applying the algorithm using python by following a step by step guide, and practical applications/use cases that will be demonstrated in the oil and gas industry.
