Dear Oil and Gas Authority,

I am referring to the following report in the Times on 30 June:
https://www.thetimes.co.uk/article/earth...

Where the OGA is quoted as follows:
"The OGA said it was aware that UKOG made an announcement about flow testing but understood it had not taken place at the time of the earthquake."

Various other reports quoted OGA as saying that flow testing had not started before the earthquakes on 27th and 29th June.

Can the OGA clarify the basis on which these statements were made ?

Can the OGA clarify whether any activity on the borehole had started before or on 27th June (such as well cleaning, stimulation, etc)?

Yours faithfully,

Ada Zaffina

Dear Oil and Gas Authority,

You have not replied to my FOI request "Horse Hill request for information" promptly, as normally required by law.

Can you please provide an answer to my questions today.

Yours faithfully,

Ada Zaffina

Dear Oil and Gas Authority,

I note your response contained within a response (https://www.whatdotheyknow.com/request/5...) to a related FOI (https://www.whatdotheyknow.com/request/h...)

The response reads:
"In relation to your second email of 26 August, the OGA has been in regular
discussions with HHDL on this matter and was aware that the EWT commenced on 9
July 2018, nearly two weeks after the seismic events in Newdigate. In addition, the
OGA had been informed that no activity on the borehole had started before or on 27
June 2018."

The related FOI asked for copies of communications between OGA and Horse Hill Developments Limited or UK Oil & Gas Plc for periods: 1st March to 15 April and 1st June to 15 July 2018. No communication about the commencement of EWT on 9 July 2018 was provided.

Shall I take this that there is no documentary evidence at all of the start date of the EWT being 9 July 2018?

Yours faithfully,

Ada Zaffina

OGA FOI requests, Oil and Gas Authority

Dear Ms Zaffina,

Thank you for the follow up to your FOI request FOI-2018-0046.

The date of the 9 July start of the EWT was not held, in recorded form, during the time periods specified in your request.

It may also be helpful for you to know, if you were not already aware, that the Oil and Gas Authority recently published a summary and conclusion of the workshop held on the 3rd October 2018 to investigate the recent Newdigate seismic events.
Information and evidence presented at this workshop have also now been made publicly available, this includes an Operational summary of activity at the Horse Hill 1 wellsite.
This summary is directly available here: https://editor.ogauthority.co.uk/media/5...

You can find further information on the Newdigate Seismicity Workshop that you may find useful from the link below:

I hope that this is helpful.

Yours sincerely,

FOI Officer.
