Fracturing/pressure pumping
This work evaluates CO2-based fracturing as a sustainable development approach for shale gas reservoirs in the Burgos Basin of Mexico.
This case study presents the first field deployment of acoustic fracturing analysis to evaluate perforation efficiency and implement real-time interventions during 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 describes a smart-tracer-portfolio testing and design solution for multistage hydraulic fracturing that will, write the authors, enable operators to reduce operating cost significantly and optimize production in shale wells. -
The complete paper demonstrates the benefits of honoring data measurements from a multitude of potential sources to help engineers do a better job of including more diagnostics into routine operations to provide additional insight and result in improved models and completion designs.
-
As operators feel the pinch of low oil prices, so, too, do their service providers.
-
Though they have been a niche ever since their introduction to the market a few years ago, e-fleets are proving to be some of the most downturn-proof assets in the shale sector.
-
The cementing services market size in the US is expected to drop 50% year-on-year from 2019. The significant drop in Permian Basin activity will account for 40% of the total market size reduction.
-
Faster drilling speeds have become one of the major obsessions of the shale sector in recent years. But since completions represent up to 70% of a new well’s cost, maybe this side of the business needs more attention now.
-
The room for error and cost overruns just got a lot smaller with the escalating need to make operations more efficient and leaner with fewer resources and investors continuing to prioritize ESG alongside profitability.
-
While many shale producers are racing to cut costs by removing crews from the field, ExxonMobil and Chevron stood out as maintaining large numbers of fracturing crews.
-
When engineers went searching for clues on how fractures move beneath the surface, they expected to uncover important learnings. They did not know they were on the path to a new invention.
-
Shale producers are pulling completions crews out of the field to respond to the recent price crash, but the contraction has only begun.
