OGA Agrees Work Programme and Extends Retention Area Periods for Horse Hill Licenses, Weald Basin, SE UK
The Company announces that it has been informed by the operator, Horse Hill Developments Limited ("HHDL"), that the Oil and Gas Authority ("OGA") has consented to extend the current PEDL137 and PEDL246 Retention Areas ("RAs") until 2021. The PEDL137 and PEDL246 RAs, which cover the entirety of the licences, will now expire on 30th September and 30th June, 2021, respectively. The Company holds a 6.5% net interest in the licences via its 10.0% ownership of the licence's operator HHDL.
The RA work programmes, now agreed with OGA, comprise; the planned Horse Hill-1 ("HH-1") Kimmeridge and Portland production tests, HH-1z Kimmeridge Limestone ("KL") and HH-2 Portland appraisal wells, 50 km² of 3D seismic, 25 km of 2D seismic in PEDL246 and a PEDL246 exploration step-out well. The RAs for each licence can be further extended or modified subject to an ongoing minimum work programme agreed by the OGA.
HH-1 Oil Discovery
The HH-1 Kimmeridge Limestone and Portland oil discovery well is located within onshore exploration Licence PEDL137, on the northern side of the Weald Basin, 3 km north of Gatwick Airport. As previously reported in February and March 2016, two naturally-fractured limestone members within the Kimmeridge section, known as KL3 and KL4, flowed dry, 40-degree API oil, at an aggregate stabilised natural flow rate of 1,365 barrels per day ("bopd") with no clear indication of depletion. The overlying Portland flowed dry, 35-37 API gravity crude at a stable pumped rate of 323 bopd. The Portland was produced at the rod-pump's maximum achievable rate and thus flow was constrained by the pump's mechanical capacity.
As previously reported in October 2016 and March 2016, an application for long term production testing and further appraisal drilling was submitted to Surrey County Council in October 2016, and is now scheduled to be decided at the Council's planning committee meeting in July 2017. The Company therefore envisages that these operations will commence in the second half of 2017 upon grant of the necessary remaining regulatory permissions.

Glossary:
degree API | a measure of the density of crude oil, as defined by the American Petroleum Institute |
discovery | a discovery is a petroleum accumulation for which one or several exploratory wells have established through testing, sampling and/or logging the existence of a significant quantity of potentially moveable hydrocarbons |
limestone | a sedimentary rock predominantly composed of calcite (a crystalline mineral form of calcium carbonate) of organic, chemical or detrital origin. Minor amounts of dolomite, chert and clay are common in limestones. Chalk is a form of fine-grained limestone |
Retention Area ("RA") | An area covering all or part of an onshore UK "14th Round New Model" Licence that can be retained until the expiry date without any relinquishment and subject to a work programme agreed by the OGA. Usually, as in the case of PEDL137 and PEDL246, the Retention Area covers the entire Licensed area |
seismic | use of reflected and refracted sound waves generated at the surface to ascertain the nature of subsurface geological structure. 2D seismic records a two-dimensional cross-section through the subsurface collected using the two-dimensional common mid-point method. 3D seismic records a three-dimensional image through the subsurface using the common depth-point method. |
step-out | a well designed to determine the lateral extent of a discovered hydrocarbon accumulation or play |
