Analysis of non-stationary waterflooding application in oil fields of OAO «Udmurtneft» V.A. Nasyrov, S.I. Kachurin, V.P. Cepelev, CJSC «Izhevsk oil science centre» In the article non-stationary waterflooding application in oil fields of OAO «Udmurtneft» efficiency is carried out. Firstly, simple (abstract) formations were studied for correlating efficiency with working regime, then working with real development objects. Simulation models and well-known methods were the main investigation instruments. Moreover, statistic analysis of actual cyclic waterflooding operations was made to figure out key factors, affecting the efficiency of such processes in the formation. Keywords: сyclic waterflooding, simulation modeling, efficiency calculation, optimum half-cycle calculation, application statistics.
