A thermal oil recovery process in which steam is injected into a heavy oil-bearing formation through a horizontally-drilled injection well and oil is produced through a horizontal production well parallel to the injection well.
In a method for the enhanced recovery of a viscous oil from a subterranean, oil-bearing formation by injecting steam into the formation through at least one injection well and producing oil from a plurality of separate producing wells situated at an offset from the injection well, the improvement wh
In a method for the enhanced recovery of a viscous oil from a subterranean, oil-bearing formation by injecting steam into the formation through at least one injection well and producing oil from a plurality of separate producing wells situated at an offset from the injection well, the improvement which comprises (a) a plurality of substantially parallel horizontal production wells, and (b) a plurality of vertical injection wells located between each pair of adjacent parallel horizontal production wells and spaced apart along the center line between each of said pairs of parallel horizontal production wells at distances equal to the separation of said parallel horizontal production wells.
