Enhanced recovery
The objective of this microfluidic investigation is to identify and test two novel applications for magnetic fluids in porous media for subsurface oilfield applications.
This paper describes a study to design and implement an enhanced oil recovery project via a huff ’n’ puff using Y-grade injectant.
This study compares water-based chemicals that can be used for enhancing the oil recovery of shale-oil reservoirs, including surfactants, nanoparticles, and ketones.

A project to predict how much carbon dioxide injected into an oil field is likely to remain there forever set off the US Department of Energy (DOE) on a search for faster data analysis methods. -
For more than 50 years pressure transient tests have been used to model conventional reservoir properties in wells all over the world. In unconventional reservoirs, it was first assumed this kind of test could not be done; however, a sensitive pressure gauge technology makes it possible.
-
As shale operators look for ways to survive amid the current downturn in oil prices, accelerating the refracturing of older horizontal wells is turning into one of the most attractive options.
-
Hybrid steam/solvent processes have gained importance as a thermal-recovery process for heavy oils in recent years.
-
An even temperature conformance along the length of the horizontal well is key in maximizing steam-assisted-gravity-drainage (SAGD) production rates.
-
Polymer flooding in sensitive areas can require the transport of polymer fluids over long distances. Conventional wisdom limits transport distance or degradation occurs. This paper argues that critical velocity, not distance, is the controlling factor.
-
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.
-
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.

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.”
