Fracturing/pressure pumping
This paper discusses the development of a multientry, multistage fracturing system and its advantages over traditional openhole multistage fracturing solutions.
In the Marcellus, Repsol is slicing and dicing legacy data to evolve its completions strategy, while in the Permian, ExxonMobil is mastering the 4-mile lateral drillout using lessons learned.
Two new studies from completions experts suggest the global upstream industry has a major opportunity in medium-quality reservoirs.

The second edition of the SPE International Hydraulic Fracturing Technology Conference and Exhibition opened in Muscat, Oman, yesterday with more than 395 oil and gas professionals from 90 companies and 28 countries. -
Even though total produced volumes are projected to hit new record highs in the coming years, treated water is expected to be comparatively lower than in the past, despite water disposal practices increasing oilfield seismic activity, with earthquakes nearly doubling in West Texas alone in 2021.

It appears to be possible to sense how fractures change during production using ultrasensitive fiber-optic strain measurements.
-
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).

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 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.
-
This paper analyzes several configurations of convolutional neural networks suited for predicting upscaled fracture permeabilities and shape factors required to close a dual porosity/dual permeability model.
-
The authors write that simple and straightforward observations on outcrops can be used to build 3D models that mimic geological relationships accurately.
