• Drilling at Ginny/Hermine (Company 9%) expected to commence in December

• Rig confirmed for Kveikje and Cambozola wells, to be drilled in 2022

• Copernicus well site survey to be acquired shortly, to facilitate 2022 drilling, following well commitment decision

• Executive team further strengthened through additional ex-Faroe appointment of Hilde Salthe as Managing Director, Norway

Rødhette exploration well spud

The drilling of the Rødhette prospect (Company 20%) has commenced using the deep water Scarabeo 8 semi-submersible drilling rig. This is a proven Jurassic play in the Hammerfest Basin with the potential for early monetisation through a 30km tie-back to the Goliat Field.

The well, operated by Vår Energi, is expected to take up to six weeks to drill with an estimated pre-carry net cost to Longboat of c.$7 million (c.$1.5 million post tax).

The Rødhette prospect is estimated to contain gross mean prospective resources of 41 mmboe with further potential upside to bring the total to 81 mmboe. The chance of success associated with this prospect is 41% with the key risk being related to fault seal and oil column thickness.

Drilling schedule 2021

The following three additional near-term wells are scheduled for drilling in 2021:

Drilling of the Egyptian Vulture prospect (Company 15%) is expected to commence towards the end of September using the West Hercules semi-submersible drilling rig, which is on a long-term contract with the operator, Equinor. The Egyptian Vulture well is targeting gross mean prospective resources of 103 mmboe with further potential upside to bring the total to 208 mmboe on a gross basis. The chance of success associated with this prospect is 25% with the key risk being related to reservoir quality and thickness.

Drilling of the Mugnetind prospect (Company 20%) is also scheduled to commence at the end of September using the Maersk Integrator jack-up drilling rig. The Mugnetind prospect, operated by AkerBP, is estimated to contain gross mean prospective resources of 24 mmboe with further potential upside estimated at 47 mmboe on a gross basis. The chance of success associated with the Mugnetind prospect is 51% with the key risks being reservoir presence/quality.

Drilling of the dual-target Ginny and Hermine prospects (Company 9%) is now scheduled to commence  in December 2021, using the West Hercules semi-submersible drilling rig operated by Equinor. These prospects have a combined target gross mean prospective resource of 68 mmboe with further potential upside estimated at 129 mmboe on a gross basis. The chance of success associated with these prospects are 27% and 22%, respectively, with the key risk being related to fault seal and phase risk.

2022 Drilling Programme

Longboat is pleased to confirm further details of its 2022 exploration drilling programme which will see the Company participate in three additional wells.

The Company has recently been informed by Equinor, the operator, that the Deep Sea Stavanger semisubmersible drilling rig has been contracted to drill the Kveikje (Company 10%) and Cambozola (Company 25%) exploration wells in H1 2022.

Kveikje is a low-risk, Paleocene injectite play located near the Fram infrastructure offering opportunities for rapid commercialisation. Cambozola is a significant, play-opening well located near some of the largest fields on the Norwegian Continental Shelf. Further details about both wells, including size and chance of success, can be found on the Company’s website.

Additionally, following the well commitment made on Copernicus (Company 10%) at the end of August, the acquisition of a site survey is anticipated to be acquired shortly which will facilitate the drilling of an exploration well during 2022 by operator PGNiG.
