Estimation of the risk of behind-the-casing flow from water-bearing bed to an interval of the oil reservoir perforation

Authors: R.S. Khisamov, I.A. Nuriev (Tatneft OAO)
The analysis of a technical state of Tatarstan terrigenous Devonian wells with behind-the-casing circulation and wells, placed in operation in 2006 – 2008, is given. Produced output watering dependence on the distance between perforation interval and the nearest water-bearing bed, and also on the proportion of permeabilities of water-bearing bed and perforated oil reservoir is obtained. The complex parameter of natural isolation of the reservoirs, allowing quantitatively to determine the probability of behind-the-casing flow, is calculated
