Doriemus PLC - Planning Application for Appraisal and Drilling

“Doriemus is excited that the Horse Hill oil play at Gatwick Airport is finally, subject to planning approval, moving further along the path to appraisal and development, with this important submission of the necessary planning applications to the Surrey County Council. The planned long term flow testing and the drilling of 2 new wells, including one low cost sidetrack well, should significantly enhance Horse Hill’s value to shareholders and stakeholders’ and assist Doriemus towards near term oil production and oil revenues from this important onshore UK oil discovery. It is also an important step in furthering our knowledge of the Kimmeridge limestone plays beneath our acreage in the Weald, especially our interests in the Brockham and Lidsey production fields.”

Subject to the required regulatory approvals, the first phase of the proposed development is planned to consist of the extended production testing of four zones, designed to confirm the commerciality of the discovery, and to examine a previously untested Kimmeridge limestone.

The planning application also seeks permission for a two-well drilling phase, which contingent upon successful testing, will further appraise the extent of the oil accumulations and the field’s production capabilities. The proposed drilling phase includes plans for a deviated sidetrack, HH-1z, to be drilled from the existing HH-1 borehole, together with a new well, Horse Hill-2 (“HH-2”). On completion of drilling, both the HH-1z and HH-2 are planned to be long-term production tested.

In order to minimise the impact to the locality, feedback from both a public consultation and engagement process, undertaken in July, and subsequent meetings with local residents’ representatives, was incorporated into the envisaged development design and planning application. The normal local planning authority cycle for an application not requiring an Environmental Impact Assessment such as at Horse Hill, takes approximately 13 weeks.
