Course description
History Matching and Reservoir Optimization - HMRO
This course is designed to cover state-of-the-art techniques/workflows for history matching geologic and reservoir models for both conventional and unconventional reservoirs. The course will discuss manual and assisted history matching methods and also, inverse modeling techniques and the pros and cons of the methods. The production/history data can be in the form of pressure or rate transient tests, tracer tests, multiphase production history, or interpreted 4D seismic information. Field examples will be presented to illustrate the current state of the art and limitations. The use of history matched models for optimizing reservoir development and management strategies will be discussed. These include: optimal infill well-placement, rate optimization/well allocation for maximizing sweep efficiency, and optimizing well completions in unconventional reservoirs. The course will involve a combination of theoretical discussion, practical applications, and computer exercises using public domain software to provide the participants with hands-on training on the workflows that can be applied using available commercial software.
This course covers both conventional and unconventional reservoirs.
"Really enjoyed being exposed to streamlines and how much can be accomplished using them." - Rerservoir Engineer, Ghana
