induced seismicity
-
A magnitude 5.0 quake was followed by a magnitude 4.7 temblor, both in Culberson County in West Texas, an area that is already being watched by the Texas Railroad Commission, the state's oil regulator, because of a jump in seismic activities.
-
At SPE’s Permian Basin Energy Conference, operators shared behind-the-scenes details on innovations such as drilling horseshoe wells and trimulfrac completions along with in-basin challenges such as handling produced water.
-
A series of temblors in the region has been linked to oil and gas extraction processes.
-
A seismic prediction model is developed and presented in a case study to simulate the magnitude and timing of triggered seismic events with the intent to manage and mitigate environmental impacts resulting from induced seismicity during subsurface development activities.
-
The Permian’s produced-water challenge presents an opportunity for innovation to pave the way toward a more sustainable future for the industry.
-
Permian Basin oil wells produce a lot of water. Much of it is injected into disposal zones above and below the basin’s primary oil- and gas-producing zone. When water is injected into these disposal zones, the pressure increases, mainly because no fluid is concurrently removed. Is this increase in pressure a concern? The data would suggest yes.
-
The 5.2-magnitude earthquake is tied for the fourth strongest in Texas history. It occurred in an area where oilfield companies have long been injecting waste water.
-
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.
-
New research reveals waste water injected underground by fossil fuel operators caused a magnitude 5.6 earthquake in November 2022 in the Peace River area of Alberta’s oil sands region.
-
The recent Permian Basin earthquakes in Texas are keeping producers, regulators, and service providers busy in their quest to reduce the intensity and frequency of the induced seismic events.
