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.

After a year of field testing, a new type of biopolymer developed by Wintershall, Germany’s largest oil and gas producer, is showing promise as an effective enhanced oil recovery (EOR) tool in one of the country’s longest producing oil fields. -
A growing chorus of suppliers, researchers, and service companies is persuading US operators to re-examine their use of slickwater in shale plays and consider displacing it with carbon dioxide and nitrogen.
-
For companies working to maximize production and profits, one of the biggest questions has been, and continues to be, how manyu wells to drill per square mile.
-
Some operators are returning to their North American mature unconventional shale wells to refracture, or restimulate, the rock to accelerate production and enhance ultimate recoveries.
-
The number of subsea wells has increased steadily to more than 5,500 by the end of 2012.
-
This paper presents a concept for recovery in Canadian oil sands that uses water injection to condition a reservoir interval sufficiently to relieve the overburden stress on the oil sand and increase its porosity and permeability.
-
To increase the production of a heavy-oil reservoir offshore Congo, a study of DHEH applications has been carried out with encouraging results.
-
Work conducted in the Surmont field of Alberta, Canada, provided an excellent starting point to optimize flow-control improvements to the SAGD process.
-
Research into whether CO2 can be used to coax billions more barrels of oil from unconventional formations is beginning to show promise.
-
Tests showing increased recoveries in the Bakken formation using CO2 could have significant implications for the upstream oil and gas industry.
