A displacement fluid may then be injected into the casing to displace the cement into the annular space, wherein a combined volume of cement and anti-corrosion fluid fills the annular space along a height of the casing. A height of the cemented annular space may be less than the height of the casing, the anti-corrosion fluid being retained in the annular space axially above a cemented annular space, forming an anti-corrosion fluid annular space. Partially cementing in this manner may simultaneously protect the casing from corrosion while allowing easier workover operations proximate the anti-corrosion fluid annular space. | 2021-12-23 |

20210396110 | GAS-PHASE SOLVENT MANAGEMENT DURING PRODUCTION OF IN-SITU HYDROCARBONS - Methods for producing hydrocarbons from subterranean reservoirs are disclosed herein. The methods utilize a production well that comprises a plurality of fluid-inlet components are spaced apart to define a plurality of production-well fluid-inlet zones. The methods comprise injecting an injection fluid comprising a solvent into the reservoir, such that a drainage fluid comprising a liquid phase and a gas phase occupies one or more of the production-well fluid-inflow zones. The method further comprises producing a production fluid at a production-flow rate via a pump, and modulating the gas phase:liquid phase ratio of the production fluid by orchestrating variations in the pump speed and one or more of the plurality of fluid-inlet components to prioritize hydraulic communication with a subset of the plurality of production-well fluid-inlet zones. | 2021-12-23 |
20210396111 | METHODS FOR RECOVERING SOLVENT AND PRODUCING HYDROCARBONS FROM SUBTERANEAN RESERVOIRS - Disclosed are methods of producing hydrocarbons and recovering solvent from a subterranean reservoir that is penetrated by an injection well and a production well. The methods comprise orchestrating a production phase that involves injecting solvent (and optionally steam) to mobilize viscous hydrocarbons. The methods also comprise a solvent-recovery phase that involves non-condensable gas injection. The production phase and the solvent-recovery phase are each defined by an injection profile. The solvent-recovery-phase injection profile is selected: (i) based on the production-phase injection profile, and (ii) to ensure the pressure/temperature conditions in proximity to the production well favour gas-phase solvent recovery. | 2021-12-23 |
20210396112 | CONFORMANCE CONTROL IN HYDROCARBON RECOVERY - Processes are provided for conformance control in the production of hydrocarbons from reservoirs, involving the distribution of mobilizing injection fluids into a formation through a number of injection fluid distribution points spaced apart along an injection well. The volume and/or position of mobilizing fluid outflows at the distribution points is adjusted based on criteria that include selected reservoir parameters measured at spatially distributed measurement points in the reservoir. An operational system is provided so that these measurements provide a proxy for recovery chamber conformance. | 2021-12-23 |
20210396113 | METHOD AND SYSTEM FOR COMPLETING A WELL - Disclosed herein is a method of injecting a fluid into a subterranean formation, the method comprising: placing a first wellbore in the subterranean formation; injecting the fluid through the first wellbore into the subterranean formation at an injection rate of R1, wherein R1 is varied with time or fixed; subsequently injecting the fluid through the first wellbore into the subterranean formation at an injection rate of R2 for a duration of time D1, wherein R2 is varied with time or fixed; subsequently injecting the fluid through the first wellbore into the subterranean formation at an injection rate of R3, wherein R3 is varied with time or fixed. | 2021-12-23 |
