Rig Arrival at Horse Hill: HH-2 Operations Commence
UK Oil & Gas PLC (London AIM: UKOG) is pleased to announce that operations for the new Horse Hill-2/2z ("HH-2/2z") Portland horizontal well, in which the Company has an 85.635% controlling interest, have commenced. The start of physical drilling operations or "spud" is expected shortly following completion of the rig-up process and will be reported in due course.
Drilling will commence with the HH-2 vertical pilot programme and will be followed directly by the horizontal well section, HH-2z, with a planned trajectory of around 1000m wholly within the Portland reservoir. Drilling operations are expected to be completed in approximately 60 days. The HH-2z horizontal will then be tested using a bespoke downhole electric pump, or ESP.
Immediately prior to rig arrival, test production from the HH-1 Kimmeridge oil pool was temporarily shut-in to permit a safe rig-up process and will be resumed prior to the pilot hole spud. Kimmeridge test production is planned to continue throughout the drilling campaign.
Before the current shut-in, Kimmeridge test production totalled 39,205 barrels ("bbl") of dry Brent quality crude, with average daily rates of up to 307 bbl of oil per day recorded following the resumption of production on 12 September 2019. Total aggregate Portland and Kimmeridge test production now stands at over 68,773 bbl.
Following UKOG's recent acquisition of Tellurian's 35% interest in Horse Hill, the Company now holds a controlling 85.635% interest in the field and surrounding highly prospective PEDL137 and PEDL246 licences, which continue to be operated by UKOG's subsidiary company, Horse Hill Developments Ltd, in which UKOG holds a 77.9% direct controlling interest.
Stephen Sanderson, UKOG's Chief Executive, commented:
"The journey to long-term oil production at Horse Hill has now begun. We look forward to a safe and successful drilling campaign at our flagship asset."

Glossary
horizontal well | a well that during drilling is steered so as to follow and remain within a particular geological stratum or reservoir unit having a trajectory that runs approximately parallel to the top and or base of the target horizon |
oil field | an accumulation, pool or group of pools of oil in the subsurface that produces oil to surface |
well test | or flow 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. |
