The proposed steam flood optimization workflow incorporates field surveillance data and numerical simulation, driven by machine learning and AI enabled Algorithms, to predict future steam flood reservoir performance and maximize NPV for the reservoir. The process intelligently determines an optimal current field level and well level injection rates, how long to inject at that rate, how fast to reduce rates on mature wells so that it can be reallocated to newly developed regions of the field. A case study has been performed on a subsection of a Middle Eastern reservoir containing eight vertical injectors and four sets of horizontal producers with laterals landed in multiple reservoir zones. Following just the steam reallocation optimization process, NPV for the section improved by 42.4% with corresponding decrease in cumulative SOR by 24%. However, if workover and alternate wellbore design is considered in the optimization process, the NPV for the section has the potential to be improved by 94.7% with a corresponding decrease in cumulative SOR by 32%. This workflow can be extended and applied to a full field steam injection project.
Dr. Erdle is CMG’s Vice President for software sales and support for the USA and Latin American. He has 44 years of industry experience, primarily in reservoir and production engineering-related positions within the services and software segments of the E&P industry, since graduating from Penn State with BS and PhD degrees in Petroleum Engineering in ’71 and ’74. Early in his career Jim was involved with some of the industry’s leading advances in well testing design, monitoring and interpretation technology, including Closed Chamber and Surface Pressure Readout (SPRO) Drill Stem Testing, production enhancement via NODAL analysis, stimulation treatment design & monitoring techniques, and production surveillance software (The Production Analyst, which was the predecessor to OFM).
Jim joined CMG in May of 1997 and by October of that year had opened CMG’s USA office in Houston. Since then he has been responsible for expanding CMG business in the USA, in the GCC countries of the Middle East (2003-2008), and since being promoted to Vice President in June of 2008, in South/Latin America. Jim has been directly involved in improvements to CMG’s technology, including the workflows available within CMG’s products used to build, run and analyze dynamic reservoir simulation models of Unconventional (Shale/Tight) Gas and Liquids-rich reservoirs.
Jim has co-authored several recent SPE papers on the subject of modelling unconventional wells (SPE #’s 125530, 125532, 175122, 180209, 180974), and is the author of Chapter 8 (Application of Numerical Models) in SPEE Monograph # 4 “Estimating Ultimate Recovery of Developed Wells in Low-Permeability Reservoirs” (2016). firstname.lastname@example.org
