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.

This paper focuses on the effects of injected-gas composition and fracture properties on oil recovery, concluding that cyclic gas injection in hydraulically fractured shale oil reservoirs is feasible for improving oil production substantially over primary production. -
Initially, polymer flooding had not been considered as a viable enhanced-oil-recover (EOR) technology for Pelican Lake in northern Alberta, Canada, because of the high viscosity of the oil until it was considered in combination with horizontal wells.

Saudi Aramco’s plan to create a global network of research centers is becoming a reality. It recently celebrated the opening of its Houston center that the company’s President and Chief Executive Officer Khalid Al-Falih described as “an upstream research center like no other.”

Surface jet pumps (SJPs) are simple, low-cost, passive devices that use a high-pressure (HP) fluid as the motive force to boost the pressure of produced-gas and -liquid phases.

Polymer flooding has been used to enhance the production of oil from mature fields in Oman. This article discusses the trial of several approaches to improve the treatment of water produced from these fields.

A major heavy oil producer in California has agreed to test a device that is designed to reduce emissions of smog-producing gases and increase the efficiency of gas burners.

Production of low-viscosity liquids, including condensates, from tight reservoirs such as shales is severely restricted by the ultralow permeability of such formations, limiting production to a very small fraction, usually less than 5%, of the liquids in place.

An operator has launched a successful, limited-scope deployment of a nonparametric capability known as event detection and association (EDA).

Demand for a better way to remove carbon dioxide (CO2) from natural gas led to the creation of a new material at Rice University in Houston that does something unprecedented on the molecular scale, and might even change gas processing.

"Smart water" is needed for effective waterflooding in carbonate reservoirs. A novel water-ionic technology, comprising nanofiltration and reverse-osmosis membrane-based processes, was identified for optimization in this study.
