Numerical
simulation provides a thorough understanding of the geologic and reservoir
parameters that are significant to the production performance. It also
permits optimization of oil recovery through studies of alternate exploitation
plans. These may include waterflood, thermal methods, miscible gas, and
chemically enhanced oil recovery.
A reservoir model is generated using the engineering-geologic data and history matching the reservoir performance. A forecast of the future performance is then made for various operating conditions.
Matching laboratory coreflood results and translating pertinent parameters to the field model calibrates chemical flood performance. The objective of numerical modeling an oil field is to determine the most profitable exploitation plan that fully utilizes the resource.
