Angus Energy oil production plans for Brockham wellsite

Angus Energy has revealed plans to produce oil from an existing well at its Brockham site near Dorking in Surrey.

It also proposes to plug and abandon part of a sidetrack at the centre of a planning dispute more than four years ago.

In leaflets distributed to homes near the site, Angus said it wanted to reperforate the upper section of the BRX4 well to reach oil in the Portland sandstone:

“The perforation of the Portland Sandstone reservoir would target a new zone in an existing well, avoiding the need to drill a new well and improving the potential to enhance recovery of hydrocarbons from an existing wellsite.”

According to the Oil & Gas Authority, no oil has been produced from any of the wells at Brockham between November 2018 and June 2021, the most recent date for which figures are available.

Angus Energy has posted a formal notice that it intends to apply for planning permission to reperforate, retain and produce from the BRX4 well.

The notice, required under planning regulations, is official notification to owners or tenants of land to which an application for mineral working relates.

Under Article 13 of the Town and Country Planning (Development Management Procedure) Order 2015, the notice must be displayed for not less than seven days in the period of 21 days immediately before the application is made to the local planning authority.

Any representations about the plans must be made by 4 November 2021 to Surrey County Council’s planning department.

This period does not replace any public consultation period when the planning application has been submitted and published.

The application must be validated by Surrey planners before it is posted online and opens for public comments. DrillOrDrop will report on the application when it is published.

Plugging and abandon

Angus Energy also said in its leaflet that it intended to plug and abandon part of the controversial BRX4z borehole, part of which targeted the Kimmeridge formation.

This sidetrack well was drilled in January 2017, without planning permission, according to Surrey County Council.

Angus Energy disputed this but was granted retrospective planning permission in August 2018.

It later said it believed the Kimmeridge reservoir at Brockham was unviable. The leaflet said Angus did not “intend to attempt further work on this formation from the BRX4z well.”

Plugging and abandonment of the Kimmeridge section would be covered under an existing previous planning permission, the company said.
