Enhanced recovery
This case study presents a procedure in which the operator compared production from wells with adjusted wettability to a control group, finding that the adjustments resulted in significant improvements in production and reductions in produced water.
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.
-
A normal five-spot polymer-flooding pilot has been conducted at the Mangala field, one of the largest onshore fields in India, and results are encouraging -
Several studies explored the possibility of improving both areal and vertical sweep efficiency in mature water-alternating-gas (WAG) patterns in the Magnus oil field.
-
Foams have proved to be efficient at temporarily blocking high-conductivity layers and improving gas-injection conformance and sweep efficiency in predominantly matrix reservoir systems, at least in laboratory and field pilot tests.

What a difference a year can make! Back in June 2014, when the EOR Operations feature last appeared in JPT, Brent was trading at more than USD 100/bbl.
-
This paper presents performance, results, and learnings from the first solar enhanced-oil-recovery (EOR) project in the Middle East/North Africa region
-
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.
-
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.
-
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.
-
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.
