Brockham regional location within the Weald Basin, southern UK

Angus Energy is the operator and majority partner of production licence PL235 located in the Weald Basin, onshore UK. Angus currently holds a 65% interest in the Brockham field.

The Brockham field was first discovered by BP in the late 1980’s and since then has a long history of production from the Portland Sandstone, a conventional sandstone oil reservoir. Production from the Portland Sandstone has continued since discovery in the 1980’s right up to the last few years. The field has undergone a steady and predictable decline in production rate as the asset has matured.

In February 2017 Angus Energy drilled the BRX4Z sidetrack to assess the prospectivity of oil production in the Kimmeridge Clay formation, a formation that had flowed oil from the Angus Energy drilled Horse Hill-1 well only a few miles away. Following drilling and testing it was confirmed that the Kimmeridge would not flow commercial volumes of oil and the well is now suspended.

Currently the site has a water replacement pressure support well (BR3), a Portland Sandstone production well (BRX2Y) and the BRX4Z sidetrack. Angus Energy still see’s significant value in the Brockham field and intends to continue production from the Portland Sandstone via the BRX2Y well, while also injecting produced water in the BR3 well to maintain pressure support in the reservoir and to increase oil production. The company is also evaluating the potential to perforate the BRX4Z sidetrack in the Portland Sandstone and isolate the Kimmeridge section to further increase the recovery of the remaining Portland oil pool. Angus Energy hopes to have all regulatory permissions to produce, inject, and perforate effectively in the near future and maximise recovery from the mature Brockham asset.
