Reservoir and Fluid Characterization with Formation Testers: Reducing Asset Uncertainties

Society of Petroleum Engineers Distinguished Lecturer 2018-19 Lecture Season   Reservoir and Fluid Characterization with Formation Testers: Reducing Asset Uncertainties                                               Cosan Ayan     Abstract:   Formation Testers (FT) have been around for more than 50 years. Early 1990’s, have seen the emergence of pumpout wireline formation testers (WFT) which modernized their applications, including better fluid sampling, permeability and anisotropy measurements and basic downhole fluid analysis. Now, the technology is advancing further in both hardware and software as we are entering a new era in formation testing. While the industry is pushed to reduce costs, compromises on reservoir and fluid characterization can have detrimental effects in new projects and emerging FT applications are well poised to provide critical answers to reduce asset uncertainties.   In this lecture, we will briefly focus on existing and emerging hardware/software on formation testing but our focus will be on applications of acquired and interpreted data for reservoir and fluid characterization.  We will discuss pressure gradient analysis and implications of gradient errors for reservoir engineers.  We will review the effects of OBM contamination on fluid uncertainties and the choice of inlet types on cleanup behavior.  Emerging downhole fluid analysis sensors will be discussed and a new deep transient testing method will be introduced.  In-situ stress testing with WFT will be outlined with drilling and reservoir engineering applications. We will discuss these points with field examples. Finally, desired features of next generation WFT will be outlined.   Biography:   Dr. Cosan Ayan was a Reservoir Engineering Advisor for Schlumberger Wireline Headquarters based in Paris, France, who has opted for early retirement in June 2017.

Formation Evaluation and Petrophysics: From Technical to Business Impact

Abstract: It is commonly accepted that petrophysics/ formation evaluation is critical for quantitative full field evaluation, yet the perception among some is that its mostly about expensive logging, calculating net-to-gross, porosity and saturation. However, from a business perspective, it’s much more than that. Petrophysics is integral throughout the life cycle of the field, and one of the aims of this talk is to show that by engaging your petrophysics teams early, and keeping them engaged through the process, significant business uplift can be achieved. In particular, this talk will highlight a concept known as the “petrophysical value chain” as it relates to exploration, development and production. This talk will also use show some real world examples of how logs, if incorrectly interpreted, can result in lost opportunities, and that sometimes, the interpretation is itself bounded by the complexities of the operations itself, requiring more than just logging to get to an answer that makes (economic) sense. Finally, there will be a discussion on how petrophysicists must avoid the “silo” effect that can come with being practitioners of this discipline. About the Speaker: Munish Kumar is currently a Sr. Petrophysicist with Total Asia Pacific Exploration, based in Singapore. His focus is on operational petrophysics and formation evaluation of assets in Asia, Australia and the Pacific region. Prior to this, he was a Sr. Petrophysicist with ExxonMobil (Exploration, Development and Production) in Australia and Houston, working on fields in Alaska, Gulf of Mexico, Mexico, W. Africa, Indonesia, Papua New Guinea, North West Shelf and Gippsland Basin, Victoria. He has a PhD in Physics and Engineering (Applied Mathematics) from the Australian National University (2010) and a BEng (Hons) in Electrical and Computer Engineering from the National University of Singapore (2005).

Big Data Analytics: What Can It Do For Petroleum Engineers And Geoscientists?

Big Data Analytics: What Can It Do For Petroleum Engineers And Geoscientists?                                               Srikanta Mishra     Abstract:   Big data analytics has become quite the buzzword in recent years, and its growing application in E&P operations promises to be an exciting new development.  It involves: (1) acquiring and managing data in large volumes, of different varieties, and at high velocities, and (2) using statistical techniques to “mine” the data and discover hidden patterns of association and relationships in large, complex, multivariate datasets.  The ultimate goal is to extract as much intelligence from our ever-expanding trove of data to improve operational efficiencies and make better decisions for optimizing the performance of petroleum reservoirs.  However, the subject remains a mystery to most petroleum engineers and geoscientists because of the statistics-heavy jargon and the use of complex algorithms. In this talk, I will provide a “gentle” introduction to big data analytics by focusing on: (a) easy-to-understand descriptions of the commonly-used concepts and techniques, (b) broad categories of E&P problems that can be solved with big data analytics, and (c) case studies demonstrating the value-added proposition for big data. The one key idea I would like to offer as a takeaway is this : There is significant potential for data analytics to provide insights that can be translated into actionable information in E&P projects, but petroleum engineers and geoscientists need to have a fundamental understanding of data-driven modeling concepts, their applicability and limitations.     Biography:   Dr. Srikanta Mishra is Institute Fellow and Chief Scientist (Energy) at Battelle Memorial Institute, the world's largest independent contract R&D organization, where he manages a geoscience-oriented technology portfolio related to computational modeling and data analytics for geological carbon storage, shale gas development and improved oil recovery projects.  Dr. Mishra is the author of “Applied Statistical Modeling and Data Analytics for the Petroleum Geosciences” recently published by Elsevier, and has also taught multiple short courses on uncertainty quantification, statistical modeling and data analytics.  He holds a PhD degree in Petroleum Engineering from Stanford University.

Democratization of LNG - Small Scale LNG and Feedstock Demand

Abstract: LNG is known as a transition fuel in our quest to reduce emissions and avoid catastrophic and runaway global warming.   While large gas to power projects (Gigawatts size) receives attention, LNG’s success will eventually be measured how it is used for small scale purposes and as feedstock to replace the high carbon liquid fuels. This means, LNG needs to be democratized.       For instance, in ASEAN context, the goal is to supply electricity to the remaining masses and to ensure energy security with the right mix. LNG fits nicely into this goal. However, the challenge is to supply LNG to areas with poor infrastructure where it can fire up small factories and micro power plants. For instance, in Indonesia, there are many power plants which are diesel fired in remote areas. There is a good economic case for LNG to displace diesel for these power plants if the correct value chains are configured. Further, to substitute other liquid fuel (Naphtha), LNG has to evolve into feedstock.   This presentation will discuss: Challenges in the democratization of LNG Small scale LNG uses and challenges Possible use of LNG for other purposes like feedstock   About the Speaker: Rao Shivaprakash is currently a Senior Associate at Advisian, WorleyParsons Group. He leads the Hydrocarbons consultancy team in Advisian’s global center of excellence for LNG regasification based in Singapore. He has worked in many diverse roles within LNG, Hydrocarbons, Petrochemical and Specialty Chemicals Industry over 23 years. Shiva holds a MBA in Finance and accredited degree in Chemical Engineering.   His key strengths include strategic analysis, project management and implementation. ​​​

Development of Organic Shales Outside North America

Abstract:    The success of organic shale development in North America has brought a great interest in organic shale exploitation internationally. The employed drilling and completion practices are based on the techniques that have been successful in US, and hydraulic fracturing treatments are primarily dominated by slickwater owing to its low cost and benefit in maximizing the stimulated reservoir volume (SRV). However, the international shale plays are usually in high tectonic stress environment, complex geological structures, and frequently contain natural fractures, which are quite different from most of the plays in US with relatively simple structure and more relaxed stress environment. These complexities have resulted in additional challenges in both reservoir understanding and completions, and ultimately production performance. Proppant placement issues and casing deformation are commonly experienced in slickwater treatments in these tectonically active plays, and production results were below expectations in the early phase of the development. Numerous studies have been performed and revealed the stress sensitivity in all the wells in which the fracture system starts to deteriorate when the effective stress reaches the critical value, resulting in many perforation clusters not contributing to production. This leads to an important conclusion that fracture conductivity is equally important as the SRV for high stress organic shale plays, and the treatment strategy shall be recalibrated from current slickwater treatments. The presentation provides an overview of challenges in these organic shale plays with high tectonic stresses, and highlights a few important findings and practices that would address the problem and improve production performance.   Biography:   Liu Hai is Technical Advisor on production and stimulation in Schlumberger, and Domain Manager for Middle East and Asia region.

Production Optimisation of Conventional and Unconventional Wells with ESP Real Time Data - Sponsored

Sponsored Kindly by Artifical Lift Solutions Pty Ltd  Abstract: Optimising production has always been important, but there is naturally a greater focus on high rate wells, such as those produced with ESPs (Electrical Submersible Pumps). A key driver is arresting decline while minimising infill drilling, which is often achieved by identifying wells with skin to identify stimulation candidates and increasing drawdown on wells with good pressure support. With unconventionals, accelerating production while minimising power consumption become dominant goals. This presentation explains how real-time gauge data enables high-frequency, high-resolution downhole flow rate measurements on ESP wells. Thereby providing both rate and pressure, which are essential to enabling inflow characterisation and thereby identifying optimisation opportunities without the need for traditional buildups, which cause production deferment.   Fortunately, technology advances have improved real time data quality in terms of both sampling frequency and metrology.  There has also been a reduction in the cost of measurement, transmission and storage, which signals the true dawn of the digital age. The presentation therefore also reviews how real time data enables increases in well uptime and ESP run life as well as minimising power consumption.  Using material from recent SPE papers, both theoretical methodology and real case studies are presented to illustrate the value of real time data for both conventional vertical wells and unconventional multifracked horizontal wells.  While the case studies are based on ESP applications, the lessons learnt on how to extract value from real-time data can be applied to other artificial lift techniques, especially since inflow characterisation is generic.   Biography: Lawrence Camirelli has over 33 years of experience in production operations of which 27 years have been focused on artificial lift in a variety of roles ranging from field and application engineer to his current role as Global Domain Head, which is Schlumberger’s most senior technical position in the Artificial Lift Division.  He has published over 16 SPE conference papers and 3 patents covering all aspects of ESP operation such as inflow characterization and advanced completions.  This body of work is particularly noteworthy as it combines theoretical explanations and field case studies using real time data.

Compositional Simulation that is Truly Compositional

Abstract:    Current compositional simulators include compositional equation-of-state fluid models, but do not account for compositional effects on relative permeability, capillary pressure, and grid-block flux calculations.  Relative permeability, for example, is still based on “old thinking” related to labeling of phases as “oil, gas, and water.”  Labeling causes significant discontinuities that can result in inaccuracies and instability in simulations of compositional processes, such as those for enhanced oil recovery (EOR).    This presentation will show you why labeling is “old thinking” and how labeling generates discontinuities and simulation errors in compositional processes.  Several example cases, including water-alternating-gas and surfactant flooding, are given using a new type of compositional simulator with all labels removed.   One component of the novel simulator is the development of an equation of state (EoS) for relative permeabilities that eliminates phase labeling.  The relative permeability model is physically based and captures complex hysteresis effects through saturation and phase connectivity as well as changing wettability, interfacial tension, and pore morphology.   Results show increased robustness, improved accuracy, faster computational times, and less instabilities when phase labeling is removed.   Biography:   Russell T. Johns is the George E. Trimble Chair of Energy and Mineral Sciences at the Department of Energy and Mineral Engineering at The Pennsylvania State University. He also holds the Energi Simulation Chair in Fluid Behavior and Rock Interactions.  He recently served as Chair of the Petroleum and Natural Gas Engineering Program, and is currently the Editor-In-Chief for SPE journals.    Prior to his current position at Penn State, he served on the petroleum engineering faculty at The University of Texas at Austin for fifteen years.  He also has nine years of industrial experience as a petrophysical engineer with Shell Oil and as a consulting engineer for Colenco Power Consulting in Baden, Switzerland.  He holds a BS degree in electrical engineering from Northwestern University and MS and PhD degrees in petroleum engineering from Stanford University.  He has over 250 publications in enhanced oil recovery, thermodynamics and phase behavior, unconventional gas engineering, multiphase flow in porous media, and well testing.  Dr. Johns received the SPE Ferguson medal in 1993, the SPE Distinguished Member award in 2009, the SPE Faculty Pipeline award in 2013, the 2016 SPE international award in Reservoir Description and Dynamics, and the 2018 Wilson Excellence in Research award from the College of Earth and Mineral Sciences.  He is currently director of the Enhanced Oil Recovery consortium in the EMS Energy Institute at Penn State University.

Porosity Determination from Mechanical Measurements in Carbonates

Abstract: The advent of pressurised mud cap drilling (PMCD), where an underbalanced mud (“light annualar mud”, LAM”) is continually pumped down the annulus into a reservoir whilst drilling, allows for safe drilling of highly porous and permeable formations such as carbonate reefs. It has been applied successfully to wells drilled onshore and offshore in Papua New Guinea. The downside of the PMCD technique is high losses of seawater, drilling mud/fluid and cuttings into the formation leading to both porosity occlusion and an altered borehole environment inconsistent with assumptions used in classical log analysis. This makes evaluation of wireline and even logging whilst drilling logs problematic, with difficult determination of porosity and water saturation (Kyi, Han, Lee, Roberts, & Maeso, 2015). Since the initial point at which the bit penetrates the rock is when the rock has had least exposure of time to any invasion, it is proposed that the problems faced by conventional interpretation of electrical logs can be resolved through application of an alternative method that measures mechanical rock properties at the bit as the rock is drilled. This insight is not new. The term “drilling porosity” refers to techniques by which porosity of a formation being drilled could be determined solely from mechanical measurements such as rate of penetration, weight on bit and rotational speed without the need for any separate electrical logging tool. It is no coincidence that the introduction of drilling porosity methods coincided with the advent of computerised mud logging units in the late 1970s which allowed digital recording of surface drilling parameters for the first time. Accurate monitoring and collection of surface drilling data was a necessary component for development of drilling porosity logs. Mud logging companies promoted the use of drilling porosity as a real-time indication of reservoir quality and pore pressure during drilling (Zoeller, 1972). However, details behind the methods used were not published, presumably to preserve competitive advantage. As logging whilst drilling tools gained in popularity the technique has fallen into disuse, and drilling porosity is seldom used by industry today.
