Enhanced recovery
This paper describes the operator’s initiative to reduce greenhouse-gas emissions and recover additional hydrocarbon, monetizing it as sales gas, by integrating upstream and downstream gas facilities in a unified approach.
This paper introduces a novel steam-sensitive flow-control device designed to restrict the production of steam and low-subcool liquids while allowing higher mobility of oil-phase fluids.
This study integrates laboratory testing with reservoir simulation to evaluate the effectiveness of autonomous inflow-control valves in managing late-life steam-assisted gravity-drainage production challenges.

This paper presents the design and development of a prototype intelligent water-injection and smart allocation tool aimed at achieving autonomous waterflood operations. -
Traditional oil extraction methods hit a snag in noncontiguous fields, where conventional flow-based EOR techniques falter. In southwest Texas, a producer faced imminent shutdown of its canyon sand field due to rapid production decline. Field tests using elastic-wave EOR determined whether the field could be revitalized or if a costly shut-in process was inevitable.

Oil production from thin-oil-rim fields can be a challenge considering early gas breakthrough and high gas/oil ratio. This study evaluates the performance of autonomous inflow control valves (in comparison with inflow control devices and sand screens) and their effectiveness in improved oil recovery in such fields.
-
To avoid costly interventions like sidetracking or wellbore abandonment, a check-valve system was installed near the sandface within three injector wells which prevented the mobilization of fines from the reservoir into the wellbore by stopping backflow.

This paper describes the potential, challenges, and opportunities of using a modified steam-assisted gravity drainage configuration in the Mukhaizna heavy oil field in suboptimal operating conditions.
-
This study aims at understanding the effect of a surfactant known as a high-temperature emulsifying agent as an additive to the steam-assisted gravity drainage process and the possibility of forming oil-in-water emulsions.
-
This paper describes the implementation of a hybrid technology of cyclic steam stimulation and foam into the heavy oil field development plans of the Middle Magdalena Valley basin in Colombia.

The long, successful history of various metallurgies in EOR wells has been cited as sufficient to allow the same completions for CCS injection wells. The lack of actual data on the long-term performance of these alloys in EOR wells in combination with the more-stringent requirements for Class VI wells suggests otherwise.
-
In this paper, the effect of cold-water injection on pressure transient analysis (PTA) of geothermal reservoirs is studied by varying the temperature of the injected cold water from room temperature to reservoir temperature.
-
These papers underscore the industry’s shift toward more efficient practices, each contributing a crucial piece to the larger puzzle of EOR.
