MODIFIED CONTINUOUS DRIVE DRAINAGE PROCESS

摘要

A method of producing hydrocarbons from a subterranean formation. The method comprises the steps of: building an array of at least three horizontal wells (10a, 10b and 10c); establishing injectivity in the formation; establishing communication between adjacent horizontal sections of wells (10a, 10b and 10c) in the array; injecting a fluid through the horizontal section of an outer well (10a) while producing hydrocarbons and associated fluids through the horizontal section of a well (10b) immediately adjacent to the outer well; and simultaneously applying the steps of injecting and producing to adjacent remaining pairs of wells (10b and 10c) in the arrray so that with respect to any particular well (10b) that is being used for fluid injection, each well (10a and 10c) in said array immediately adjacent to it is being used for fluid production, and wherein the hydrocarbons and associated fluids are produced at a cumulative rate of production from the entire array that establishes a pressure differential between the wells (10a, 10b and 10c) in the array.
