Fracturing/pressure pumping
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.
The US supermajor is using one of its lowest-value hydrocarbon products to generate double-digit production increases in its most prolific US asset.
The collaboration has announced Closed Loop Fracturing, which combines real-time subsurface data with automated surface control.

The contraction of the shale sector and its operations such as drilling and completions due to COVID-19 and the drop in oil price has sifted down to the frac sand suppliers. -
Carbon dioxide (CO2) waterless fracturing uses liquid CO2 to replace water as the fracturing fluid in reservoir stimulation. The continuity and reliability of the blender are key factors determining performance of the operation.
-
In an era where capital markets are hitting the brakes on funding the US shale sector, operators have increasingly pivoted from production growth to maximizing the rates of return via lower-cost wells.
-
New report offers guidelines for pressure pumpers of the future.
-
As wells across the US shale sector are brought back onto production, they may want to do so strategically to learn about the connectivity of their wells. One challenge will be in selecting a model that delivers the most insight.
-
Developed by the large shale producer, its new way to monitor interactions between horizontal wells is now available as a commercial software. The concept is considered a stepping stone toward real-time fracture design.
-
The new software enables high-resolution, real-time fracture-stage data to be shown on top of multiple previous stages to visualize optimized performance or to be tracked against an ideal preset stage.
-
A new real-time-visualization (RTV) technology combined with high-resolution pressure reading and acoustic sensors is being used to overcome operational difficulties and to optimize stimulation efforts by reducing uncertainty.
-
In the complete paper, the authors derive a novel analytical solution to model the temperature signal associated with the shut-in during flowback and production periods.
-
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.
