Abstract:
Methods for producing hydrocarbons from subterranean reservoirs utilize a production well having a plurality of individually-actuatable fluid-inlet components that are spaced apart to define a plurality of production-well fluid-inlet zones. An injection fluid including a non-condensable gas (NCG) is injected into the reservoir, such that a drainage fluid including at least a portion of the NCG occupies the production-well fluid-inlet zones. The gas phase:liquid phase ratio of a production fluid is modulated by identifying at least one of the production-well fluid-inlet zones as having a gas content above a threshold and thus being a higher-gas zone, and actuating variations in pump speed and the flow states of the plurality of fluid-inlet components adjacent and corresponding to the higher-gas zone to prioritize hydraulic communication with a subset of the plurality of production-well fluid-inlet zones spaced apart from the higher-gas zone.
