Fracturing/pressure pumping
This paper describes an alternative lower-completion concept for developing Lower Wilcox reservoirs referred to as high-angle multifractured well design.
The SPE International Hydraulic Fracturing Technology Conference and Exhibition opens with calls to adapt technology while addressing regional realities.
Casing deformation has emerged as a major challenge in China’s unconventional oil and gas fields, prompting the development of new solutions to address the issue.

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.
