Resumption of shale gas exploration
Hydraulic fracturing operations for shale gas in the UK have been suspended since May 2011, pending the investigation of two seismic tremors experienced near Preese Hall, Lancashire during fracking operations.
In the light of the recommendations of a panel of independent experts, of comments received in response to a public consultation, and of the recommendations of an authoritative review of the scientific and engineering evidence on shale gas extraction made by the UK’s science and engineering academies, the Royal Society and the Royal Academy of Engineering, the Secretary of State for Energy has announced the introduction of new regulatory requirements to ensure that seismic risks are effectively mitigated.
Read the Secretary of State’s statement to Parliament . Subject to these new requirements, DECC is prepared in principle to consider new applications for consent to such operations, and the suspension is therefore lifted. As before, final consent to any well or well operations is dependent on confirmation that all other necessary permits and consents have been obtained. A wide range of other issues were raised in the responses to the public consultation, and DECC together with other relevant bodies has prepared a full Q&A brief on these issues, which can be found below.
The full Government response to the recommendations made on the scientific and engineering evidence by the Royal Society and the Royal Academy of Engineering can be found below:

On 1 April and 27 May 2011 two earthquakes with magnitudes 2.3 and 1.5 were felt in the Blackpool area. These earthquakes were suspected to be linked to hydraulic fracture treatments at the Preese Hall well operated by Cuadrilla Resources Ltd. The hydraulic fracture treatments were carried out during exploration of a shale gas reservoir in the Bowland basin. As a result of the earthquakes, operations were suspended at Preese Hall and Cuadrilla Resources Ltd were requested to undertake a full technical study into the relationship between the earthquakes and their operations.
Cuadrilla submitted to DECC a synthesis report with a number of technical appendices on 2 November 2011, and published this material on their website. These reports examine seismological and geomechanical aspects of the seismicity in relation to the hydraulic fracture treatments, along with detailed background material on the regional geology and rock physics. They also estimated future seismic hazard and proposed recommendations for future operations to mitigate seismic risk.
To assist DECC in evaluating these studies and recommendations, DECC asked three leading experts in the fields of seismology, induced seismicity and hydraulic fracturing to make an independent assessment of the Cuadrilla-funded studies; Dr Brian Baptie, BGS; Professor Peter Styles, Keele University and Dr Christopher A. Green, GFRAC.

Further information supplied by Cuadrilla in the course of this assessment is available as Annexes below. The independent experts have now made recommendations to DECC for mitigating the risk of induced seismicity resulting from continued hydraulic fracturing at Preese Hall, Lancashire and elsewhere in Great Britain.
