Course Duration: 4 days | Time: 9am to 1pm | Course Locations: VILT, Lagos, Houston, San Diego
The key objective of this workshop is to come up with options for you to explore for the optimal development and/or reservoir management of your gas cap-oil rim. Many operators are facing with low ultimate oil recovery because of high GOR due to gas coning/cusping/influx into the oil rim and in some cases high WOR also due to aquifer influx. Development and management of oil rim with gas cap is much more complex than typical development of oil reservoirs without gas cap. Despite these challenges, there are gas cap-oil rim reservoirs with ultimate recovery factors exceeding 60%. In this workshop we will looking at several case studies around the world where gas cap-oil rim development and reservoir management are done effectively leading to high oil ultimate recovery. Several successful and failure case studies will be discussed. Videos will be played to compliments the lectures. Participants are encouraged to give a 15 minutes presentation of own challenges and blockers to increase production
2.Fundamentals of gas cap-oil rim development
Large gas cap Small gas cap Gravity drainage Gravity Drainage-Waterflood-Interaction Double displacement Zero flaring Voidage replacement strategy Sorg vs Sorw The impact of geology 3.Participants to present own challenges and issues for feedbacks.
4.Case study from around the world
North America (large gas cap => 60% URF)) North America (Maximized utilization of produced gas => 70% URF) North Africa (Double Displacement => 80% URF)
All interested in efficiently develop and manage oil reservoirs with gas cap or find creative use of the high gas production. Participants are encouraged but not required to bring own laptop with Excel software installed.
