Fracturing/pressure pumping
This paper provides an account of the design, implementation, and operational insights from an enhanced geothermal system proppant stimulation targeting a volcanic, dry rock setting with an approximately 330°C bottomhole temperature.
The paper describes a multientry multistage fracturing technology developed to enable longer laterals, increase stage counts, improve stimulation efficiencies, and derisk operations.
This work demonstrates that a carefully engineered wireline perforation strategy can address the challenges of long-interval high-pressure/high-temperature completions with large intrareservoir-pressure differentials safely and effectively.

Fracture monitoring to optimize fluid volumes and designs remains a critical area of development. Research is ongoing with the focus on combining different monitoring technologies including tracers, fiber optics, downhole cameras, and microseismic monitoring. -
The mid-sized completions service provider is betting that automation will boost the competitiveness of natural gas-powered pumps.

Two US test sites have fractured hot, dry rock with plans to create a network of fractures for water heating. They will soon find out if the fractures worked as expected.

This article presents a new data-driven analysis to locate low-frequency seismic sources, referred to as near-infrasound or infrasound sources. Combining these infrasound signals with microseismicity signals allows for better characterization and monitoring of the stimulated reservoir volume.

Fracturing hot rock to create a geological water-heating system is like fracturing an oil well, but for a different purpose, so is proppant really necessary?
-
When confronted by extremely hot wells drilled into hard rock, engineers start looking for new tools and then ask, is there a cheaper option?
-
From refracturing old wells to ones that don’t have to be fractured at all, notable producers argue that experiments are paying off.
