  • Post-CHOPS: What Happens to the Wormholes?

    Wednesday, March 21, 2018, 12:00 PM - 1:00 PM MT
    Abstract The CHOPS process involves the growth of high permeability channels (wormholes) into the reservoir. The wormholes provide improved access to the reservoir, thereby substantially increasing oil production rates. Field evidence and laboratory experiments indicate that wormholes tend to persist as stable high-permeability flow channels throughout the duration of the CHOPS process. The existence of wormholes in the reservoir needs to be taken into consideration in the design of post-CHOPS recovery processes. One of the key issues is the stability of wormholes during the re-pressurization phase of any follow up process to CHOPS. For example, wormholes could remain as stable high permeability flow channels to deliver injected fluids into a reservoir or they could collapse to improve conformance for fluid injection. This presentation describes the results of laboratory experiments testing the stability of wormholes under conditions that could be destabilizing such as cold and hot water circulation, heating, and pressurization with hydrocarbon gases (methane, ethane).   Bio Ron Sawatzky is a Principal Researcher with InnoTech (formerly Alberta Research Council) in Edmonton, with nearly 30 years of experience working in research and development for heavy oil recovery processes. For many years he served as a team leader for the cold production research group at ARC. He was an SPE Distinguished Lecturer in 2008-09.

  • Developments in Heavy-Oil EOR for the Era of Low Oil Pricing - Jose Gonzalo Flores

    Wednesday, April 18, 2018, 12:00 PM - 1:00 PM MT
    Society of Petroleum Engineers  Distinguished Lecturer     Developments in Heavy-Oil EOR for the Era of Low Oil Pricing                                              Jose Gonzalo Flores Abstract In low oil-price environments, it is customary to cut expenses, reduce staff and postpone most, if not all, capital investments. While this strategy may be financially sound in the short term, it completely disregards the essence of the oil business, that is the timely replacement of reserves. The problem further complicates in the case of heavy oil projects, where costs are higher and the product price is even lower. This presentation confronts the audience with the dilemma of reducing cost and at the same time sustaining production and increasing recoveries. The balance resides in the quality of decisions, such as when and where to invest, and that results meet budgets, a common issue in our industry. In the most complex and financially challenging case of Enhanced Oil Recovery (EOR) projects, decision quality in combination with “fit-for-purpose” technology implementations offer the most promising middle-point, this is the central idea in this presentation. By providing 8 examples of innovative technologies to help reduce uncertainty, cost and time for commercial EOR oil, and 3 successful case studies, the audience will gain confidence in the proposition that is perfectly viable to double recoveries in the next 15 years. Finally, EOR is a business, as such, it needs to compete favorably in cost and time with other alternatives present in a company’s E&P portfolio, particularly in low-price environments. A strategy, illustrated by an example, on how to divert from the traditional engineering approach in favor of a managerial decision approach will help engineers justifying viable recovery projects.   Biography Jose Gonzalo Flores is an independent consultant and instructor in the areas of production and reservoir engineering of heavy oils.  Previously, he worked for Schlumberger and Occidental Petroleum Corp. covering a 30-year period, in roles involving the structuring, leading, advising and field implementation of production optimization and improved recovery projects, and as instructor for NExT, globally.  Flores holds a B.S. degree from the Universidad Nacional de Ingeniería, Lima, Peru, and M.E. and Ph.D. degrees from The University of Tulsa, Tulsa, Oklahoma, all in Petroleum Engineering.  He is considered an expert in the areas of reservoir and production enhancement and strategies to increase the recovery factor in heavy oil and mature fields, and has over 45 publications in the literature.  Flores is a member of the SPE, and regularly serves in steering and technical roles in conferences, forums and workshops.  Currently, he serves in the SPE Editorial Review Committee and as co-chair of the 2016 SPE Latin America Heavy Oil Conference.
