Horse Hill: Alba Mineral Resources announces completion of planned high rate Portland test sequence

Alba Mineral Resources has announced that it has been informed by Horse Hill Developments Ltd, the operator of the Horse Hill-1 Kimmeridge and Portland oil discovery, located in licence PEDL137, in which Alba holds an 11.765% beneficial interest, that the planned high rate Portland test sequence, designed to assess the reservoir's maximum short-term flow capacity, has been successfully completed.

Stable implied daily pumped rates of 401 and 414 bpd of dry 36 API oil were recorded over two periods of 6 and 2 hours respectively, with associated maximum half-hourly pumped rates of 441 and 470 bpd. Metered solution gas rates of around 41 000 ft3 per day were recorded through the test separator over the two maximum rate periods.

Highlights:

  • Portland short-term high rate tests achieve stable implied equivalent daily pumped rates of 401 and 414 bpd of dry 36 API oil over two periods of 6 and 2 hours, respectively. Maximum instantaneous half-hourly pumped rates of 441 and 470 bpd.
  • The maximum rate recorded was limited by the rod pump's maximum rate capacity of approximately 470 bpd. Higher capacity rod pump sourced and mobilised for use at HH-1.
  • Metered daily oil rates and recovered Portland volumes, to date, exceed 2016 test values.
  • Associated solution gas rates of around 41 000 ft3/day.
  • Forward extended well test (EWT) programme includes flow optimisation necessary to determine the maximum sustainable long-term flow rate and a lengthy stabilised flow period to test whether the well accesses a commercially viable oil volume.
  • The further EWT objective, to establish the commerciality of the Kimmeridge Limestone 3 & 4 oil pools, will follow directly after the completion of the Portland test sequence.

George Frangeskides, Alba's Executive Chairman, commented:

"These latest positive Portland results continue to build on the Portland tests conducted in 2016. It should be stressed, however, that these short-term, high rate test results are not the long-term sustainable rates of production from the well on which the assessment of commerciality will be based and that Portland testing operations are continuing. Following the completion of the Portland test programme, the Operator will move directly onto the long-term Kimmeridge test programme, with the objective being to establish the commerciality of the Kimmeridge Limestone 3 & 4 oil pools. We look forward to providing further updates on progress as we move through the programme.”
