First gas from Tolmount field delayed

Published by , Editor

Harbour Energy has said that during final commissioning and testing of the HGS Tolmount platform in the Southern North Sea issues were identified in certain offshore electrical systems. These issues are now being investigated and rectification plans are being developed.

As a result, Tolmount first gas will be delayed beyond the end of July and is now likely to be around year-end. With expected plateau rates of 20-25 000 boe/d net to Harbour, Tolmount was expected to contribute just over 10 000 boe/d to Harbour’s 2021 production.

Due to the current uncertainty around the timing of Tolmount start-up, the company has revised its production guidance for the year to exclude volumes from the project. As a result, Harbour’s 2021 production guidance is now 185 to 195 000 boe/d on a proforma basis and 170 to 180 000 boe/d on a reported basis. This revised guidance also reflects actual proforma production to the end of June of 180 000 boe/d and a delayed restart of Elgin Franklin following the summer maintenance shutdown. Forecast full year operating costs of US$15-16/boe and total CAPEX of US$1.1 billion are unchanged.
