As announced on 8 June 2020, a Technical Committee of Hurricane’s Board was established to re-examine the full range of possible geological and reservoir models for the Lancaster field (the “Technical Review”).

The Technical Review is ongoing and final conclusions have not yet been made. However, as a result of the review and analysis performed to date, which has incorporated both existing and new data, Hurricane’s Technical Committee has concluded that there is a reasonable probability that the oil water contact in the Lancaster field is shallower than the range of oil water contacts envisaged in the 2017 Competent Person’s Report by RPS Energy.

Consequently, the Company believes there is a risk of a material downgrade to estimated reserves attributable to the Lancaster Early Production System, and that there will also be a material downgrade to estimated contingent resources across the West of Shetland portfolio. This assessment does not take into account any production enhancement options for the Lancaster field which are currently under evaluation.

Completion of the Technical Review is expected on or before the Company’s interim 2020 results on 11 September 2020, at which point the Company expects to be in a position to notify management estimates of reserves and resources for the Lancaster field, prepared in accordance with the Society of Petroleum Engineers’ Guidelines for the Evaluation of Petroleum Reserves and Resources.
