Methods for Producing Hydrocarbons from Thin, Heterogenous Pay Reservoirs
25 Nov 21
Disclosed herein is a method of producing hydrocarbons from a subterranean reservoir, the method comprising: penetrating at least a portion of the subterranean reservoir with a first well and a second well, positioning an annulus-flow restrictor within the substantially-horizontal section of the first well at a distance, d1, from a produced-fluid inlet of the second well, injecting mobilizing fluid into the subterranean reservoir via a mobilizing-fluid injection outlet of the first well to mobilize hydrocarbons therewithin, and producing mobilized hydrocarbons from the subterranean reservoir via the produced-fluid inlet.

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.
