Horse Hill Oil Field: HH-2 Pilot Completed, HH-2z Horizontal Trajectory Underway
Alba Mineral Resources plc (AIM: ALBA), the diversified mineral exploration and development company, is pleased to announce that it has received the following update from UK Oil & Gas Plc ("UKOG"), the majority owner of Horse Hill Developments Limited ("HHDL"), the operator of Horse Hill licences PEDL 137 and PEDL 246 in which Alba has an 11.765% interest:
- Following the successful completion of the Horse Hill-2 ("HH-2") Portland pilot well, Horse Hill-2z ("HH-2z") horizontal drilling operations are now underway. HH-2z aims to deliver a circa 3,200 ft horizontal section wholly within the Portland reservoir's most oil productive zone, the presence and quality of which has been further defined by the pilot well's coring and electric logging programmes as reported by UKOG.
- HH-2/2z, the first horizontal well in the field's Portland oil pool, is designed to be retained as a future production well and to deliver flow rates significantly higher than the rates achieved from the HH-1 vertical Portland discovery well. Following a planned extensive HH-2z EWT 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.
- HH-2z operations:
o HH-2z operations were initiated through the pilot well's 9⅝" casing at the planned "kick-off" point 1320 ft below rig floor, immediately above cement plugs isolating the Portland reservoir below. The well is now building angle towards the horizontal within 8½" diameter hole and will continue down to a drilled depth of around 2300 ft, just above the Portland target zone. This section will then be cased and cemented with a 7" liner.
o The well's trajectory will then continue within 6" diameter hole, entering the Portland target zone approximately 850 ft to the southeast of the HH-2 surface location. HH-2z's expected total measured depth is around 5900 ft from rig floor, of which c. 3200 ft is planned within the reservoir's sweet-spot. The well is expected to reach its total depth around mid-November.
o To ensure the borehole remains wholly within the Portland sweet spot, HH-2z will be actively "geo-steered" during drilling to keep within a series of core and electric log-derived diagnostic geological markers delineating the zone's upper and lower boundaries.
