Abstract

​

To bring into development unswept reservoir areas and prevent nonproductive injection in channel sediments, a comprehensive approach is proposed to optimize waterflood performance in channel alluvial reservoirs confined to Cretaceous and Jurassic systems of the Republic of Kazakhstan, formed under conditions of low alluvial plain with relatively low energy flow. Based on the results of production data analysis and forecast modeling of several scenarios with different arrangements of production and injection wells, optimal well placement criteria were obtained, waterflood management options were proposed together with candidate production wells for conversion to injection, optimal injection volumes and well operation modes were determined.

Key words:

​

channel alluvial sediments, Cretaceous and Jurassic systems, flow energy, field production data, reservoir pressure maintenance system, non-productive injection, waterflood system, unswept areas, production and injection wells, interference, productivity, increase of oil recovery factor, economic efficiency, geological and reservoir simulation model, fluid, water-oil displacement, production of oil reserves
