Enhanced recovery
Coreflood experiments reveal that alkali significantly reduces viscosity loss in polyacrylamide flooding systems by minimizing adsorption and improving polymer stability under shear stress. The findings position viscosity retention as a key screening criterion for successful alkali-polymer enhanced-oil-recovery applications.
This study investigates the potential for in-situ hydrogen generation from hydrocarbons using in-situ combustion, with particular emphasis on the role of kerogen content and heating mode.
This paper presents the application of degradable particulate-diverter technology to improve oil production by effectively diverting stimulation treatment fluids away from high-water-cut, high-permeability, high-temperature producing intervals or zones.

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.
-
Water handling is becoming increasingly important as a technical and economic tool for improved oil recovery and enhanced oil recovery (EOR) projects. A global series of workshops to address these issues has been planned.
