Eleven New Permits; Seismic Event Halts Fracking In Great Britain Temporarily -- October 26, 2018
Breaking news: at last count, the Germans had zero (0) horizontal oil wells; the French had zero (0) horizontal wells; and the Brits had two (2) new horizontal wells permitted. Earlier this week, while the first well was being hydraulically fractured, a micro-seismic event (0.4 on the Richter scale) was noted; the operator was alerted to proceed with "all due caution." Sometime in the last twenty-four hours, another seismic event was noted; this time, the event registered 0.76 the Richter scale. Well, let Tsvetana tell the story:Less than two weeks after Cuadrilla resumed hydraulic fracturing in the UK for the first time in seven years, the company paused fracking at its drilling site in northwest England on Friday morning after a 0.76 on the Richter scale micro seismic event was recorded, the latest of some dozen seismic events since fracking started, but one that was above the 0.5 threshold requiring a halt.
According to regulations, in case of micro seismic events of 0.50 on the Richter scale or higher, fracking must temporarily be halted and pressure in the well reduced.
On Friday morning, a 0.76 on the Richter scale event was recorded, in an event classed as “red” in the traffic light monitoring system regulated by the Oil and Gas Authority, Cuadrilla said today, adding that “All the relevant regulators were informed without delay and we have verified that the well integrity is intact.”
Work will now pause for at least 18 hours and is expected to resume in the morning on Saturday, October 27, the company said.
Comment: I assume if much more of this goes on, the Brits will join the French and the Germans with zero (0) new horizontal wells.This is interesting. In the US, most of us like to believe that seismic events associatied with fracking are due to injecting produced water / brine produced from fracked wells back into salt water disposal wells. It has been my understanding that fracking itself was not associated with seismic events. I believe Oklahoma has had the most experience with this issue.
If I recall correctly, at least one seismic event has been associated with oil and gas activity in North Dakota but I thought it was believed to be associated with injecting produced water into a salt water disposal well. I've long forgotten the specifics. I think it's been over a year since I've read any articles coming out of Oklahoma regarding seismic events. However, the first hit returned by a google search just now was to a Business Insider article dated February 2, 2018, and yes, the correlation was with disposing produced water into saltwater disposal wells and not due to fracking directly.
