HH-2/2z Drilling Update at Horse Hill Oil Field
UK Oil & Gas PLC (London AIM: UKOG) is pleased to announce that following the completion of the 12¼" diameter hole section in its Horse Hill-2 ("HH-2") Portland pilot well, 9⅝" casing has been set and cemented into position from surface to 2,019 ft below rig floor. After setting and testing blow out preventers, expected to be completed today, the well will drill a short section of 8½" diameter hole down to the coring point, where three 60 ft cores are planned through the oil bearing Portland reservoir.
Following the coring programme, designed primarily to acquire key technical data that will ensure the 1000m HH-2z horizontal section is correctly positioned within the Portland's most oil-productive zone, the well will drill ahead to total depth, be electric logged and then plugged back to the "kick-off" point, delineating the start of HH-2z's planned 1000m horizontal trajectory. HH-2z will follow directly afterwards.
UKOG holds a controlling 85.635% interest in the Horse Hill oil field and surrounding highly prospective PEDL137 and PEDL246 licences, which are operated by UKOG's subsidiary company, Horse Hill Developments Ltd.
About HH-2/2z:
HH-2/2z, the first of two new horizontal wells in the field's Portland oil pool, is designed to be retained as a future production well, capable of delivering flow rates significantly higher than the previously reported 362 barrels of oil per day ("bopd") from the HH-1 vertical Portland discovery well. Following a planned extensive HH-2z production flow-testing campaign, both HH-2z Portland and the HH-1 Kimmeridge well are expected to be put into long term production by the end of 2019.
Stephen Sanderson, UKOG's Chief Executive, commented:
"The HH-2 pilot continues on schedule and according to plan. We look forward to the imminent coring programme, the data from which will ensure the HH-2z horizontal is optimally positioned within the reservoir, a key step towards delivering flow rates significantly in excess of the HH-1 vertical discovery well."

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. |
