A method of recovering hydrocarbons from a subterranean reservoir. The method includes drilling a substantially-vertical primary production well, drilling a plurality of offset production wells generally around the substantially-vertical primary production well in a radial orientation, and drilling a plurality of offset injection wells generally around the substantially-vertical primary production well in a radial orientation. The method further includes injecting, via the plurality of offset injection wells, a liquid to mobilize the hydrocarbons from the subterranean reservoir and inducing the mobilized hydrocarbons to migrate towards the plurality of offset production wells for secondary recovery and injecting, via the plurality of offset injection wells, a gas to mobilize the hydrocarbons from the subterranean reservoir and inducing the mobilized hydrocarbons to migrate towards the plurality of offset production wells for tertiary recovery.
