Modélisation des réservoir TAGS et l’efficacité de la réinjenction (RNS Central)

Abstract

Our work has the objective to make a TAGS reservoir modeling of the RNS field with the material balance method to understand the ideal method to develop the gas condensate reservoir. In the first part we made a presentation of the places of internship, after we made a generality on the gas field, the classification, the behavior and the properties of the fluids; as well as the various problems of exploitation of a gas-condensate field have been explained. After we have defined and explains the recovery assisted by gas injection. And at the end of this part we talk and detail the drainage mechanisms and equation of the material balance and in short the modeling of the aquifer and Simulation Second part presents the different steps followed to characterize the PVT effluent properties of RNS Central on IPM 7.5.600 simulation software, and also to estimate the reserves in place with 03 methods and model the reservoir by defining the drainage mechanisms and the evolution of production as a function of pressure. At the end, we do a provisional calculation with several scenarios and the profitability of each scenario and determination of the optimum injection rate for the TAGS reservoir of Central RNS.
