Abstract
A numerical simulation model was developed for studying the effects of element injection upon fluid flow behavior in non-uniform underground reservoirs. The model has the capability of tracking up to three phases with several components in each phase. Anyone of the three phases (oil, water or gas) is eligible to be the injection phase. The injection positions are variable so that many different patterns (well locations) can be studied. The geologic characteristics of the underground reservoir are statistically generated using known core analysis data from the reservoir as the population parameters. Four numerical solution techniques were tested using the developed model for comparison in terms of accuracy core allocation, execution times, and programming expertise. These solution tests resulted in the formulation of a new method for solving the numerical model.
