Fracking operations in the UK remain suspended pending a technical review at the Preston New Road site operated by shale explorer Cuadrilla Resources, in northern England.

Hydraulic fracturing operations have been suspended since a 2.9 magnitude tremor last month.

Industry regulators launched the investigation into the induced seismic activity, which significantly exceeded the 0.5 magnitude on the Richter scale threshold.

If the threshold is crossed, operations must stop for 18 hours, however, work was suspended, according to the Oil & Gas Authority (OGA).

“Hydraulic fracturing operations will remain suspended until the OGA’s considerations are complete,” the industry body said.

“We are continuing programmed well operations at Preston New Road,” Cuadrilla said.

“This is not a resumption of hydraulic fracturing, which is currently subject to technical review by ourselves and our regulators. We are actively continuing to monitor and verify the integrity of the wells and continue sampling activities,” the company added.

The UK shale gas explorer is also visiting the homes of locals in northern England who were reportedly affected by seismic activity caused by the company’s fracking operations in the region.
