The input data sets for compositional simulators include a large number of parameters that must be assigned carefully to represent the petroleum reservoir with an appropriate model and to make accurate and efficient simulations. With emerging expert-system technology, The University of Texas Input Parameter Selection Expert System (UTINPUT) has been developed on a workstation using NEXPERT OBJECT, an expert-system shell. C and a hybrid approach combining rules and objects were used. A customized user interface was developed and integrated with the expert system by use of NEXPERT's delivery system, NEXPERT FORMS. The resulting expert system is interactive, user-friendly, and efficient and provides the necessary expertise to create input data sets for UTCOMP. A major part of this research was accumulating expertise through literature, simulation experts, and, to a much greater extent, detailed simulation studies with emphasis on reservoir fluid characterization, selection of timestep size, and design of miscible gasfloods. The authors research shows that expert system technology can be used effectively in conjunction with reservoir simulators to simulate such complex processes as miscible gas flooding and to preserve and transfer such expertise.
