Enhanced recovery
This paper presents a novel reservoir engineering/reservoir simulation approach—a data-driven interwell-connectivity model augmented as a digital twin—to predict reservoir dynamics and optimize operations in the Changqing oil field of China.
This paper presents a study that confirms glass-reinforced-epoxy-lined tubing as a reliable, cost-effective solution for long-term water-injection service in moderate-salinity offshore environments.
This study aims to systematically assess casing integrity and corrosion risks associated with CO2 injection in oil-recovery operations.

The M4-field reservoir is approximately 2000 m below sea level in a water depth of approximately 120 m. A carbon dioxide (CO2) geological-storage study was carried out to determine the feasibility of injecting and storing CO2 in the depleted M4 carbonate gas reservoir. -
A successful field trial in which foam was used as a gas-injection conformance enhancer was implemented in the Cusiana field in Colombia.
-
A number of hurdles need to be overcome to reach a successful action/reaction, problem-free status in EOR operations.
-
The Diatomite reservoir in the Belridge field, California, has been under pressure-maintenance water injection to mitigate reservoir compaction and improve oil recovery.
-
To increase the oil recovery in the Albacora field, significant water injection is required that was not considered in the initial project-development phases.
-
Enhanced oil recovery processes, particularly offshore, create challenges for produced water treatment. This option reviews technology options and current applications.
-
Changing the salinity of injection water could make the difference in getting more out of existing wells.
-
Using low-sal water for flood can add 30% to the amount of oil that can be recovered from a reservoir. What is the theory behind it?
-
ExxonMobil is testing its Controlled Freeze Zone technology, a single-step cryogenic process that allows carbon dioxide (CO2) to freeze in a controlled method and then melts the CO2. After recovery of the methane, the CO2 can be sequestered or used for EOR.
-
Higher oil prices has created increased interest in chemical enhanced oil recovery (CEOR) using polymers, surfactants, and alkalis. This technology poses some special challenges, especially around water treatment.
