IMPROVING HYDROCARBON RECOVERY FROM AN EGYPTIAN RETROGRADE GAS CONDENSATE RESERVOIR, THROUGH THERMAL GAS INJECTION

Abstract

This work investigates the effects of gas injection (CH4, N2 & CO2) and steam at high temperatures on one of the Western Desert retrograde gas condensate reservoirs. All these injection scenarios have been simulated using Compositional-Thermal ECLIPSE simulator, after exporting the thermal PVT model from the matched compositional PVT model. Thermal CO2 injection increased the condensate production by 28.9% as it mainly improves the condensate mobility. So, it is mostly applicable for depleted reservoirs when the largest amount of non-producible liquid is already dropped out.
