This paper is dedicated to the reservoir management and the recovery drive of oil rims – depletion, barrier water flooding and gas reinjection. First, the review of world experience in development of oil rims was carried out; the performance results of different drive regimes are described. Main dimensionless criteria that influence on the character of filtration flows in tilted oil rim were formulated. These criteria take into account gravity factor, anisotropy factor, geometrical configuration of reserves of oil and gas.
The methodology of choosing the best recovery drive was presented. It resides in varying key dimensionless parameters with finding the optimal well position and individual well controls at the same time. The criterion of efficiency is discounted oil recovery due to the same number of wells in all variations. Two-dimendional, three-phase, black oil simulator was used to get the "i-chart" that points out the best recovery drive and the best well control. Such graph will help to perform snap-analysis of development of oil rims what will be especially actual for greenfields when designing concepts of systems of development.
