Utility
Process for producing hydrocarbons from a subterranean hydrocarbon-bearing reservoir
26 Oct 20
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.

Utility
Process for Producing Fluids from a Hydrocarbon-bearing Formation
6 May 20
A process for producing fluids from a subterranean hydrocarbon-bearing formation includes injecting mobilizing fluid, including a solvent, into the hydrocarbon-bearing formation through an injection well and into the hydrocarbon-bearing formation, producing produced fluids from the hydrocarbon-bearing formation to a surface through a production well, discontinuing injecting the mobilizing fluid and injecting a loss circulation material and a fluid into one of the injection well and the production well, opening the one of the injection well and the production well to perform work on the one of the injection well and the production well, and closing the one of the injection well and the production well.
