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; establishing injectivity in the formation; establishing communication between adjacent horizontal sections of wells in the array; injecting a fluid through the horizontal section of an outer well in the array while producing hydrocarbons and associated fluids through the horizontal section of a well immediately adjacent to the outer well; and simultaneously applying the steps of injecting and producing to adjacent remaining pairs of wells in the array so that with respect to any particular well in the array that is being used for fluid injection, each well 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 in the array, and wherein the cumulative rate of fluid production from the array is greater than the cumulative rate of fluid injection through the array.
