A rigless chemical frac-hit remediation process was designed to address the damage mechanisms of capillary phase trapping, reduced hydrocarbon relative permeability, paraffin deposition, and minor scale deposition.

The disruptive nature of unconventional reservoirs has spurred the need for new ideas. But that doesn’t always mean that we need to toss out the traditional methods that got us here. Such might be the case for the recent developments unfolding around the diagnostic fracture injection test (DFIT).

The authors describe a study in which leakage-rate modeling was performed to identify and evaluate the associated risks for designing a remedial action plan to safeguard a CO2 storage site.

When it comes to produced water from US shale plays, it’s either recycle and reuse or throw it away—and both are easier said than done.

The authors write that polymeric additives are effective in the design of complex systems to house important chemical reagents under challenging conditions.

Against a backdrop of global uncertainty and challenging economics, well integrity subject-matter experts have continued to prioritize human and environmental safety in production while pivoting their skills toward areas of growing importance such as carbon capture and sequestration. New technologies and simulation methods have allowed the authors of the three SPE pap…

This paper examines current practices and developing trends in well construction and describes an alternative cementless approach to the discipline.

HCl acid stimulation of carbonate production requires the retardation of the HCl-carbonate rock reaction to achieve the optimum balance between total fluid used and the enhancement of well production. The described investigation was done offshore Sarawak using Indiana Limestone cores.

The newly formed SPE Hydraulic Fracturing Technical Section is working on a project to identify a set of best practices for completions engineers. Once completed, they will be accessible to the entire SPE technical community.

Mixing dry polymer powder and water to make friction reducer as needed during fracturing can cut the cost of the additive and the testing of whether a drastically simplified recipe performs as well as more-complex mixes.
