Improved Oil Recovery for Developed Oil Rim Reservoir Using Gas Blow Down Strategy (A Case Study of Cefa Feild in Niger Delta)

One of the major production problems in the development of Oil rim reservoir is early water and gas breakthrough, thereby drastically reducing the production of oil which is the desired phase. The concept of concurrent gas and oil production is necessitated by the increased demand of gas in the gas market and also the production of gas provides room for additional oil recovery from the reservoirs. The aim of this research work is to improve oil recovery of CEFA oil rim reservoir in Niger Delta of Nigeria using gas blow down mechanism as to optimize and improve the production performance. A detailed geological reservoir static (permeability, Porosity, Water Saturation, Net-to-Gross) model with dynamic fluid and rock data served as input in setting up the dynamic model that was used for this study. The oil production rate and recovery factor as at the point of optimization proc
