Fracturing/pressure pumping
Two new US Department of Energy funding programs focus on improving shale recovery, mitigating produced-water risks, managing sour gas, and enhancing facility efficiency.
This paper presents findings reinforcing the argument that acid fracturing is a strong alternative stimulation method to improve productivity in the Austin Chalk formation.
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.

Output is rising fast in the South American shale play and putting Argentina on a course to soon reach 1 million B/D. -
Industry experts at URTeC assessed more than a decade of unconventional growth while discussing where productivity gains will come from next.
-
Chevron and Halliburton describe how they built and deployed the fully autonomous closed-loop fracturing system that enables subsurface-driven optimization.
-
The paper presents the design and successful field deployment of the first closed-loop hydraulic fracturing program.
-
This paper reviews fracturing-program design, completion technology, real-time data collection, data integration, and lessons learned for the Pikka development on the North Slope of Alaska.
-
New insights from Chevron, Occidental Petroleum, and others at the SPE Improved Oil Recovery Conference highlight the different paths companies are using to squeeze more out of tight rocks.
-
The paper describes a project in which extremely challenging stimulations were performed in a fractured tight carbonate in a complex strike/slip stress faulting regime with high tectonic stresses.
-
This study provides the first experimental evidence that in-situ combustion is feasible in Permian shale under realistic rock–fluid conditions.
