Greater Lancaster Area

It is Hurricane’s view that Lancaster and Halifax have the potential to be part of a single, large accumulation, the Greater Lancaster Area (GLA). Hurricane owns 100% of the licences covering this accumulation, P1368 Central and P2308.

P1368 Central – Lancaster

The Lancaster Field is located in blocks 205/21a, 205/22a and 205/26b, licence P1368 Central. Hurricane has a 100% interest in this licence.

The Lancaster Field was discovered by Hurricane in 2009. It sits in relatively shallow water of around 160m. Hurricane is implementing a phased development on Lancaster using the two horizontal wells drilled on the structure. The first phase of the development, the Early Production System (EPS), came on stream in June 2019. The data acquired during the EPS phase of production will help optimise future development phases in order to maximise production from the field.

The UK’s first ever exploration well targeted at a basement reservoir was drilled by Hurricane in 2009 on Lancaster. The well, 205/21a-4, discovered a pervasive fracture network and flowed light (38° API) oil to surface, demonstrating the viability of the Rona Ridge basement play.

Lancaster has been further appraised by inclined wells 205/21a-4Z (2010) and 205/21a-7 (2016) and two horizontal producers, 205/21a-6 (2014) and 205/21a-7Z (2016). Both horizontal wells have demonstrated that the reservoir is highly productive with PIs in excess of 140 stb/psi/d. 205/21a-6 flowed at 9,800 bopd using an electrical submersible pump (ESP) and 205/21a-7Z flowed at 15,375 bopd using an ESP. Both rates were constrained by the rig rather than the reservoir. 

P2308 – Halifax

The Halifax structure is located in blocks 205/22b, 205/23 and 205/24, Licence P2308. Hurricane has a 100% interest in this licence.

Greater Warwick Area

The Greater Warwick Area comprises licences P2294 and P1368 South and is being appraised/developed through a joint venture between Hurricane energy (50%) and Spirit Energy (50%). The joint venture believes that the Greater Warwick Area (GWA) is a single hydrocarbon accumulation comprising the Lincoln discovery and the yet to be drilled Warwick prospect. The joint venture undertook a three well drilling program on the GWA during 2019 and is currently evaluating the results.

P2294 – Warwick / Lincoln

Located in Blocks 204/30b and 205/26d (Licence P2294). Hurricane has a 50% interest in this licence following Spirit Energy's farm-in to 50% in September 2018.

P1368 South – Lincoln

Located in Block 205/26b, Hurricane has a 50% interest in this licence following Spirit Energy's farm-in to 50% in September 2018.

P1368 North – Whirlwind

Located in Blocks 205/21a and 205/22a (Licence P1368 North). As part of the extension of licence P1368 granted in December 2019, the subarea covering Whirlwind will be relinquished.

Whirlwind is a large, low-relief structure approximately 10km north of Lancaster, and was the second basement prospect to be drilled by Hurricane, proving to be another large discovery. 

The 205/21a-5 well was drilled in 2010 and re-entered for testing in 2011, flowing a light oil/gas condensate from an openhole test conducted over a combined Lower Cretaceous limestone and underlying fractured basement interval.

The source of the hydrocarbon is the same as for Lancaster, though the precise composition of the fluid at reservoir conditions remains ambiguous. This well is currently suspended for future appraisal, with options including re-entry for testing or a possible sidetrack being considered.

The Whirlwind structure is approximately 2,000 metres deeper than Lancaster, representing a downthrown terrace from the Rona Ridge. As such, the reservoir properties are broadly consistent with Lancaster, and should a gas export route become readily available then Whirlwind represents an excellent incremental project to the development of the area.

In their 2017 CPR that covers the Rona Ridge assets excluding Lancaster, RPS Energy reconfirmed their earlier assessment of recoverable volumes on the Whirlwind Discovery. Depending on the fluid type (which may be a light oil or gas condensate fluid type due to current sampling uncertainty), RPS attribute 205 MMboe of 2C Contingent Resources in the oil case and 179 MMboe 2C Contingent Resources in the gas condensate case.
