A Chinese operator in the Sichuan Basin used high‑frequency pressure monitoring to evaluate frac performance in unconventional wells.
Hydraulic fracturing holds great potential in the region, but there are several key questions worth asking as efforts move forward.
This paper describes the evolution of the operator’s initial PWC (perforate, wash, and cement) abandonment projects performed in deepwater Brazil.
-
Regulators told some injection well operators close to the epicenter of a magnitude 4.0 earthquake that they will have to shut down their operations indefinitely. -
This paper presents design considerations and field-trial applications for determining practical dimensions and limits for interdependencies associated with stage length, perforation clusters, and limited-entry pressures.
-
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.
-
A high-resolution acoustic downhole evaluation system nabs top award for 2023.
-
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?
-
EcoShield also reduces carbon footprint of well construction over traditional cement systems.
-
From refracturing old wells to ones that don’t have to be fractured at all, notable producers argue that experiments are paying off.
-
Over 1,000 hours of remotely monitored continuous production was achieved on an unmanned platform—a first for standalone offshore solids management in the North Sea.
