Brockham Oil Watch is a non-political group of local residents concerned about the threat of unconventional hydrocarbon extraction from the Kimmeridge Clay Formation (or other unconventional reservoirs) at Brockham, and gaps in the current legislative/regulatory framework.
We are also concerned about the level of competence of Angus Energy (current operator) given its track record around the drilling of sidetrack BRX4Z, which Surrey County Council said was unauthorised.
Your Questions Answered
Why did we form a group? Because we feel that people need to know more. Everyone is busy and doesn’t have the time to dig out information. And the information can be very complicated.
What’s the website for? To present issues in a clear and reliable way, putting both sides of the argument so that people can make up their own minds. We provide links to other sites and media, including those coming from Angus and other firms in the industry.
What’s the issue? There were a number of worrying events during recent works the main offence being unauthorised drilling of a sidetrack well. The bigger issue is that Angus are currently targeting the Kimmeridge Clay Formation – unconventional, shale-dominated stratum of very low permeability.
Commercial production of oil from the Kimmeridge layers will almost certainly require well stimulation treatments such as acidisation or hydraulic fracturing, as well as drilling of multiple, back-to-back wells. Potential risks include pollution of air, ground and surface waters, increased traffic and stress for the local community.
Brockham is in a vulnerable position because some wells at the site are permitted for production until 2036 and Angus are aiming to exploit that to skip the exploration and appraisal stages of planning.
