Further Update on Horse Hill-1 Flow Test
Portland Zone Flows Oil at a Sustained Rate of 168 Barrels Per Day
Evocutis (AIM: EVO, ISDX: EVO) announces that Horse Hill Developments Limited ("HHDL") announces that Horse Hill Developments Limited ("HHDL") has informed the Company that 37-degree API, light, sweet, dry (99-100% oil) crude has flowed to surface, via rod pumping, at an average stabilised rate of 168 barrels per day over a continuous 9-hour period. The flow is from a 103-ft aggregate perforated zone within the Upper Portland sandstone interval at a depth of approximately 615 metres below ground level. Maximum flow during this test period was restricted by the initial rod pump configuration. The flow test will now continue with a pump configuration designed to permit optimal flow over a longer flow period.
The Horse Hill-1 ("HH-1") well has now produced at a combined average stable rate of over 1,528 bopd from the two Kimmeridge and Upper Portland zones.
Horse Hill-1 Discovery Well and Licence
The exploration drilling phase of the HH-1 discovery well was originally completed at the end of 2014. The well is located within onshore exploration Licence PEDL137, on the northern side of the Weald Basin near Gatwick Airport. Evocutis owns a 1.3% interest in PEDL137.
Hamish Harris, Executive Chairman, commented:
"These results provide additional validation to the board's decision to invest in this project and we remain very positive pending further news"
Interest in Horse Hill
Evocutis owns a 2% direct interest in HHDL. HHDL is a special purpose company that owns a 65% participating interest and operatorship of Licence PEDL137 and the adjacent Licence PEDL246 in the UK Weald Basin.

Glossary
choke | Device incorporating a fixed or variable orifice that is used to control fluid flow rate during testing of an exploratory discovery |
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 |
extended flow test | a flow test, as per the permission granted by the Oil and Gas Authority, with an aggregate flow period duration over all zones of greater than 96 hours and up to 90 days maximum. |
flow test | a flow test or well test involves testing a well by flowing hydrocarbons to surface, typically through a test separator. Key measured parameters are oil and gas flow rates, downhole pressure and surface pressure. The overall objective is to identify the well's capacity to produce hydrocarbons at a commercial flow rate |
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 |
sandstone | a clastic sedimentary rock whose grains are predominantly sand-sized. The term is commonly used to imply consolidated sand or a rock made of predominantly quartz sand. |
sweet oil or crude | A type of oil that contains less than 0.42% Sulphur |
