Base gas requirements in the U.S. amount to a few trillion cubic feet. The Gas Research Institute has proposed a gas-storage operating plan whereby an inert gas or a low-BTU gas could be injected to replace part of the hydrocarbon gas. A reservoir simulator was developed to solve gas-water reservoir problems where the gas may be treated as a two-component miscible mixture. The simulator is based on a modification of SSI's standard 3-phase, 3-dimensional reservoir simulator and, therefore, it encompasses the experience of more than 20 years of simulation technology. To accomplish the task, the oil equation was removed and a means of tracking a second component (inert) in the gas phase was added. The movement of the inert component was described with the method of characteristics to practically eliminate the numerical dispersion problems associated with the solution of the flow equations with standard finite-difference methods.
