Abstract: A process for producing hydrocarbons from a subterranean hydrocarbon-bearing reservoir includes injecting a gas, at a pressure below a minimum miscibility pressure, into the reservoir through an injection well extending into the reservoir to form a gas zone in the reservoir. The gas injection pressure is suitable to provide a differential pressure between a bottom-hole production well pressure at a horizontal multi-lateral production well extending into the reservoir, and the gas injection pressure to facilitate sweeping the hydrocarbons toward the production well prior to gas breakthrough at the production well.
