Hurricane Energy PLC expects a material downgrade to Lancaster Early Production System estimated reserves and estimated contingent resources across the West of Shetland portfolio offshore UK based on re-examination of the range of possible geological and reservoir models.
Hurricane's technical committee concluded that there is a reasonable probability that the oil water contact in Lancaster field is shallower than the range of oil water contacts envisaged in the 2017 Competent Person's Report by RPS Energy.
The downgrade does not consider production enhancement options which are currently under evaluation (OGJ Online, Apr. 20, 2020).
Completion of the technical review is expected on or before Sept. 11, at which point the company expects to notify estimates of reserves and resources for Lancaster field, prepared in accordance with the Society of Petroleum Engineers' guidelines.
On Aug. 2, the Aoka Mizu FPSO underwent a controlled shutdown to undertake an inspection. The inspection identified necessary repairs which have been on going and production is expected to restart soon. The field was producing about 17,000 bo/d before shutdown (OGJ Online, July 27, 2020).
