Seismic Monitoring and Hydraulic Fracture Plan for Cuadrilla site at Preston New Road

richard parker made this Freedom of Information request to Oil and Gas Authority

This request has been closed to new correspondence from the public body. Contact us if you think it ought be re-opened.

The request was successful.

Dear Oil and Gas Authority,

I am confused as to the role and responsibility of your department in regulating the seismicity and hydraulic fracture plans generally, in particular this site that is local to myself.

I understand that from UKOOG that your department are responsible for approving and regulating plans to frack and monitor the induced seismicity, but I can find no remit of this duty on your website.

In addition, information on the hydraulic fracture plan for the above site appears to be resident via the environment agency.

Do you have any expertise/experience/input into the approval and monitoring of hydraulic fracturing and induced seismicity of unconventional oil and gas sites? Are you responsible for approval of hydraulic fracture plans? Is this role effectively passed onto the EA? Do you have any role in any environmental and public safety aspects concerned with hydrocarbon extraction? Your website indicates that your department/company is primarily, maybe solely concerned with maximising the return/output of oil and gas. Is this correct?

Yours faithfully,

richard parker

Dear Oil and Gas Authority,

On the assumption that you are responsible for approval of hydraulic track plans and the regulation and monitoring of the ensuing seismic monitoring, could you please advise on how and who approved thehydraulic fracture plan for well one of the Cuadrilla fracking site on Preston New Road. Please advise as to the procedures followed and make available to the public the technical contents of the report for us to review, in a similar manner to the way the details of the fracture plan was submitted.

In addition, could you please advise as to the review of the operation ability of the surface seismic monitoring array. Has this been checked by a government body or independent third party and why has the number of geophones been reduced from 10 to 8? Please again provide details of this anticipated inspection occurrence.

Yours faithfully,

richard parker

Thankyou for the provided information.

You have mentioned that the BGS provided a consultancy role on the trafiic light seismic monitoring array but did they provide any role in the review of the Hydraulic Fracture Plan especially with regard to the induced seismicity?

Yours sincerely,
