Control of seismicity at Preston New Road in August 2019

The request was partially successful.

Dear Oil and Gas Authority,

Following my earlier request entitled 'Traffic light schema for seismic monitoring at fracking development wells at Preston New Road', I would be grateful if you could advise on the seismic event reporting of the operator and supervisory directions of the OGA following the 1.6 seismic event of the 21st August. Could you please advise what events, presumably inclusive of this event were reported by the operator and what directions were instigated by the OGA. There seems to be some confusion over the operation of the TLS and the remit undertaken by the OGA but following my earlier request and your kindly provided answer, it would imply that no fracking would have been permitted following the 'cascaded' amber events after the 1.6 tremor. I understand that Cuadrilla then resumed fracking on the Friday 23rd which did not seem prudent or logical considering there was a substantial event of 0.4 in the early hours of the morning. I understand that the OGA is to provide a supervisory role if the seismic activity is not following the expected pattern predicted by the hydraulic fracture plan. Consequently could you please advise the times of any fracks after the 1.6 tremor of the 21st August and what reporting and liaison occurred to all subsequent seismic events of 0.0 or greater.

Yours faithfully,

richard parker

Dear Oil and Gas Authority,

In addition, could you please advise on more exact locations of the seismic events inclusive and in excess of 0.0 and the locations, times, volumes and pressures of the fracture injections of all the operations conducted at PNR in August 2019.

Yours faithfully,

richard parker

Dear Oil and Gas Authority,

Please could you advise on the progress of my request.

Yours faithfully,
