Drilling Activity Update - Jocelyn South

Ithaca Energy today announces the results of recent exploration drilling at the Jocelyn South prospect (P032) in Block 30/07a, located in the Central North Sea of the UK Continental Shelf.

Upon entering the reservoir, Harbour Energy (as "Operator") informed Ithaca EF Limited, a subsidiary of Ithaca Energy plc, holding a 33% working interest in the prospect that signs of hydrocarbons were present. The top of the Joanne Reservoir was encountered in the well at the depth of 12,620ft TVDSS (17,763ft MD). Gas condensate (not sampled) was encountered in the Joanne sandstone reservoir, with a provisional net pay thickness in the well of 434ft MD (or 307.6ft TVT). 

Logging while drilling data, cuttings and pressures were recorded during drilling to establish reservoir quality and fluid parameters. The Operator intends to complete data gathering and evaluate the drilling results to establish commerciality of the reservoir.

Jocelyn South forms part of the Harbour Energy operated J-Area, where Ithaca Energy is a partner in the Jade field (32.5% working interest), Judy field (33.0% working interest), Jasmine field (33.0% working interest) and the Talbot field (33.0% working interest) which recently achieved first production in November 2024.
