Alba Mineral Resources reports an upgrade to the conventional stock tank oil initially in place (STOIIP) volumes estimated for the overall Upper Portland Sandstone conventional reservoir in the Horse Hill-1 and Collendean Farm-1 structure, in the PEDL137 licence area in the Weald Basin.
This revised STOIIP is separate to the oil-in-place volumes estimated for the argillaceous limestones and mudstones of the Kimmeridge, Oxford and Lias rock sections of the HH-1 well, as reported on 9 April and 15 April.
The company has a net attributable interest of 6.5% in PEDL137. An independent study of the Portland Sandstone reservoir was conducted by Xodus Group, an international energy consultancy based in the UK for the Horse Hill Developments Ltd (HHDL) main consortium partners UK Oil and Gas Investments PLC (UKOG).
The study is based on new petrophysical evaluations of both the HH-1 discovery and the older Collendean Farm-1 ("CF-1") well plus an updated interpretation of 2D seismic data across the Licence. The study report is available on UKOG's website (see www.ukogplc.com). The HH-1 and CF-1 discoveries lie within an approximately 100-foot thick, Upper Portland Sandstone gross reservoir interval, within a 6km by 3km tilted fault block structure as defined by 2D seismic. The crest of the Upper Portland conventional oil discovery lies at approximately 1,760ft TVDSS, and extends over a mapped maximum areal closure of approximately 2,000 acres. The Upper Portland reservoir is productive at the nearby Brockham field, some 9km NNW, in which UKOG has an indirect interest of 3.6%.
