Completions
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 study aims to systematically assess casing integrity and corrosion risks associated with CO2 injection in oil-recovery operations.
This paper presents findings reinforcing the argument that acid fracturing is a strong alternative stimulation method to improve productivity in the Austin Chalk formation.

Predictive models may help in the estimation of produced water volumes and the optimization of the locations for water recycling and disposal facilities to reduce truck hauling distances. -
Driven by a recovery in well completions and increased proppant loading per well, the market for raw fracturing sand is expected to grow by more than 4% annually through 2021, an industry research study says.

Senior Research Scientist and SPE Distinguished Lecturer Ian Walton uses a semianalytic shale gas production model to show that natural fractures, contrary to the intuitive beliefs of many, do not contribute significantly to production.
-
Service company executives examine how the oil price downturn affected supply and demand for their services in the unconventional sector, and strategies they have undertaken to stay afloat as operators adjust to uncertainty.
-
Many of the worst oilfield incidents have been attributable to human factors. Consequently, a corporate well-control manual was refreshed to include human factors in the management of well-control incidents.
-
In a plenary session at the Unconventional Resources Technology Conference, executives in charge of unconventional operations for international oil companies talked about how they have slashed their cost per barrel.
-
The treatment in a deepwater, frac-packed well with fiber-optic-equipped coiled tubing (CT) and a rotating, hydraulic high-pressure jetting tool achieved successful stimulation of a 500-ft-long frac-packed zone after several previous failures using different techniques.
-
This paper discusses a novel approach to abrasive perforating, including the first-ever use of an acid-soluble abrasive material and ending with CT-jetting-assisted nitrified stimulation.
-
Advanced horizontal drilling, multistage hydraulic fracturing, and other technologies have helped make the Vaca Muerta shale oil and gas resource economically viable.
