This paper describes the application of dynamic local grid refinement in a multiple application reservoir simulator. Using this procedure generally enables a significant reduction of the total number of blocks necessary for a good reservoir description.

This procedure is combined with a number of EOR-options, automatic selection, variable in time of the implicitly computed variables, an ordering scheme for the equations devised specifically for the characteristics of local grid refinement, and several procedures for the solution of the system of equations. Together these features create a tool which is capable of providing quick and economic solutions to the problems encountered in reservoir simulation.
