UK Oil & Gas PLC (London AIM: UKOG) is pleased to announce that its Horse Hill-2z ("HH-2z") Portland horizontal well (UKOG 85.635% net controlling interest) has, to date, successfully drilled 2,016 ft wholly within the Portland reservoir's most oil productive zone or "sweet spot", the presence and quality of which was defined by the HH-2 pilot well's successful coring and electric logging programmes.
Following the fitting of a new rig engine, expected to be completed over the coming days, the remaining 1,200 ft of the planned circa 3,200 ft horizontal section within the "sweet-spot" will be drilled. Horizontal drilling is expected to be completed by mid-November.
Drilling data indicates that sections of possible increased reservoir quality over that seen in HH-1 and HH-2 have been encountered within the sweet-spot. Furthermore, mud weights indicate that the horizontal may lie within a reservoir zone that is less pressure depleted by HH-1 oil production than expected. A comprehensive electric logging and extended well test ("EWT") programme will further clarify these potentially positive outcomes.
HH-2/2z, the first horizontal well 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 from the HH-1 vertical Portland discovery well.
