Operations on the 205/23-3A well (the «Halifax Well») are complete.
The Company can confirm that the well is an oil discovery with initial data analysis indicating Halifax is linked to the Lancaster field forming a single large hydrocarbon accumulation.
The principal purpose of the Halifax Well was to support the Company’s view that the Lancaster Field and the Halifax prospect are one large connected structure. Well results support the Company’s opinion. The Halifax Well has successfully identified an extensive oil column, significantly below local structural closure. The reservoir interval encountered is pervasively fractured with porosities similar to those at Lancaster. The Company believes that the deeper oil down to («ODT») at 1,846m true vertical depth subsea («TVDSS») identified in the Halifax Well, compared with an oil water contact («OWC») at Lancaster at 1,678m TVDSS, is most likely caused by a tilted OWC.
Preliminary third party analysis from the Halifax Well indicates:
– a very significant hydrocarbon column of at least 1,156 metres is present within the basement extending well below local structural closure (which is at 1,040 metres TVDSS);
– that the basement reservoir below the final casing point (1,179m TVDSS) is pervasively fractured (based on initial analysis of borehole image logs processing); and
– that porosity is consistent with that at Lancaster (based on initial petrophysical analysis.
Dr Robert Trice, Hurricane’s CEO, commented:
«This is a highly significant moment for Hurricane and I am delighted that the Halifax Well results support the Company’s view that its substantial Lancaster discovery has been extended to include the Halifax licence. We believe that the GLA is a single hydrocarbon accumulation, making it the largest undeveloped discovery on the UKContinental Shelf.
The discovery of a 1km hydrocarbon column at Halifax validates the efforts the Company undertook to acquire the licence and drill, test and log the Halifax Well through the winter months. Given the positive well results, the Halifax Well has been suspended to provide the Company the option to return to undertake further testing as well as provide the option to deepen the well and thereby establish a definitive oil water contact.
