Abstract
A subterranean zone and a neighboring zone are, respectively, a petroliferous deposit and an underlying aquiferous nappe at a pressure higher than that prevailing in the subterranean zone, the two zones being separated by an intermediate substantially impervious or slightly permeable layer. A method of stimulating production of effluent from the subterranean zone includes drilling at least one deflected well, preferably nearly or totally horizontal in the intermediate layer and in connecting the two zones together through fractures of the intermediate layer made from the drain. The drain can be equipped with a pipe fitted with openings on a part of its length, with packers or like devices for effecting total or partial confining of the drain and with a fluid pressure source for causing fractures in the intermediate layer at the level of the confined portion. Through the fractures made during the production, water under pressure from the neighboring zone can be injected into the petroliferous zone which stimulates drainage of the deposit.
