Fracking paused at Lancashire website after tremors

Cuadrilla has paused fracking at its Preston New Highway website in Lancashire after what it describes as a “sequence of micro-seismic occasions”.

The agency stated in an announcement “sequence of micro-seismic occasions” in Blackpool have been recorded by the British Geological Survey on Friday.

The most important of these was a magnitude of zero.9 tremor at about 2pm, whereas staff have been hydraulically fracturing on the website in Little Plumpton close to Blackpool.

They stated: “Detected by Cuadrilla’s subtle monitoring system and verified by the BGS, will probably be classed as a pink occasion underneath the traffic-light system operated by the Oil and Gasoline Authority.”

Something measuring zero or beneath is classed as “inexperienced”, whereas recordings as much as zero.5 are “amber”, that means fracking ought to proceed with warning.

Readings above zero.5 magnitude are “pink” and imply fracking ought to be suspended instantly.

“Cuadrilla has paused and can proceed to observe micro-seismicity for at the least 18 hours after the occasion was recorded, according to the site visitors gentle system laws,” the corporate added.

“Effectively integrity has been checked and verified.”

The transfer comes simply three days after a tremor of 1.5 magnitude was recorded and fracking was suspended accordingly.

In October recurring tremors meant fracking on the website needed to be repeatedly stopped.

Environmental teams and different campaigners have tried to cease fracking on the website however in October a decide dominated there was “no proof” to indicate fracking posed greater than a “medium threat”.

The primary shale gasoline was produced on the website in November, a couple of weeks after work started.

On the time, Cuadrilla chief government Francis Egan stated: “The volumes of gasoline returning to floor at this stage are small.

“Nevertheless, contemplating that we’re solely on the very begin of fracturing operations and, given working constraints, haven’t but been in a position to inject as a lot sand into the shale as we had deliberate, it is a good early indication of the gasoline potential that we now have lengthy talked about.”
