Comments on: Is fracking behind Oklahoma’s earthquakes? Bridges, budgets, bonds Mon, 24 Nov 2014 00:29:08 +0000 hourly 1 By: Arbuckle Mon, 12 Dec 2011 17:19:55 +0000 You’re barking up the wrong tree. Fracture stimulations are not of a magnitude or at a depth to cause the large earthquakes experienced in central Oklahoma.
These are almost certainly being caused by the tremendous volumes of water being disposed into the Arbuckle Formation in this area. Most of this water is produced as a result of the exploitation of what is locally called the Hunton de-watering play.
The water injected into the Arbuckle is winding up in the pre-Cambrian basement through movement along an extensive vertical fracture system.

With the earthquakes in the 1800’s being the largest and most frequent on record.

“It’s way below any depth anybody is pumping or injecting or anything else, and it isn’t a particularly active area, oil and gas-wise,” Keller said.
Residents in nearby states have blamed hydraulic fracturing and gas injection wells for small earthquakes, and the Arkansas Oil and Gas Commission shut down some injection wells in an area where there were concerns that earthquakes were linked to oil and gas activity.
Holland has studied the swarm of smaller quakes in Oklahoma for links to the oil and gas industry, but has said he found little evidence they’re related.

By: Cate_Long Tue, 08 Nov 2011 02:00:06 +0000 A study by a group of geologists, commissioned by the company-under-scrutiny Cuadrilla and based on technical reports from a variety of survey companies , found that the fluids likely caused the pre-existing division between the rocks to lubricate. This allowed the rock formations to slide against each other more easily, causing the 2.3 and 1.5 magnitude quakes.

According to the report, “Most likely, the repeated seismicity was induced by direct injection of fluid into the fault zone. since the pressure spread out over a larger area causing the largest event 10 hours after the injection.” of-the-environment/fracking-caused-earth quakes-says-british-study
