Angus Energy plans to bring Kimmeridge into production at Brockham oil field, UK

Angus Energy has plans to bring Kimmeridge into production at its existing Brockham production facility in the UK, after an extensive analysis of the BRX4Z sidetrack well.

The company will commence production after securing necessary approval from OGA (Oil and Gas Authority).

Brockham X4Z well was drilled to a depth of 1,391m, with the objective to analyse Portland, Corallian and Kimmeridge formations at Brockham, including an evaluation of the Kimmeridge reservoir.

The well was intended to establish whether evidence of a potential reservoir reported at Horse Hill extended further north into the Brockham Licence. 

Angus Energy has revealed that the preliminary results from Brockham X4Z exhibited similar thickness of reservoir and properties to those reported at Horse Hill.

The gross thickness of Kimmeridge in Brockham X4Z is around 385m thick.

The two limestone intervals (each around 30m) tested in Horse Hill are also seen in the Brockham well. The reservoir properties appear to be similar to Horse Hill, based on electrical logging evidence.

Angus also conducted a search for natural fractures by using the Weatherford Ultra Wave Acoustic borehole imaging tool.

The tool enables the ability to see fractures in the borehole directly, thereby eradicating the need to infer them from logs.

The results confirmed natural fractures not only in the two main limestones intervals previously tested at Horse Hill, but also in abundant natural fractures in sections of interbedded shales and limestones between and below the two main limestones.

Angus procured samples during the drilling campaign for geochemical analysis.

In line with Angus’s measured approach to field development, operations are underway to install new production facilities for the well and to prepare for the production as soon as the necessary OGA approval has been received.
