Harbour has announced that during final commissioning and testing of the HGS Tolmount platform – situated in Block 42/28d, in the UK 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 kboepd net to Harbour, Tolmount was expected to contribute just over 10 kboepd to Harbour’s 2021 production.
Due to the current uncertainty around the timing of Tolmount start-up, the Harbour 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 kboepd on a proforma basis and 170 to 180 kboepd on a reported basis.
This revised guidance also reflects actual proforma production to the end of June of 180 kboepd and a delayed restart of Elgin Franklin following the summer maintenance shutdown. Forecast full year operating costs of USD 15-16/boe and total capex of USD 1.1 billion are unchanged.
