A steam drive method for low permeability formations is described which utilizes a plurality of wellbores in an elongated pattern configuration. The wells initially undergo a cyclic steaming and production operation, wherein as each steaming cycle is initiated a fracture system is created having a heated zone surrounding each fracture. The cyclic steaming and production is repeated until thermal communication between vertical fracture planes is established, and oil recovery through the single well stimulation is significantly reduced. Thereafter, cyclic steaming is halted and new injection wells, centrally situated, are established and used to initiate a steam drive, wherein the heated zone around the fractures helps to reduce the viscosity of and mobilize the hydrocarbons not initially recovered during the cyclic steaming operation.
