Talbot Field Development

Chrysaor Petroleum Company U.K. Limited, (a Harbour Energy company), as operator of the Talbot field development, acting for and on behalf of the Talbot field development owners (Harbour Energy and Eni) has made an application for consent to the Oil and Gas Authority (“the OGA”) in relation to
the above project. The OGA now operates under the business name of the North Sea Transition Authority (NSTA).

Summary of Project

The Talbot field lies within UKCS Block 30/13e, in the central North Sea region of the United Kingdom Continental Shelf and is a discovered light-oil and associated gas resource opportunity with a life expectancy of up to 16 years. The proposed development is situated in a water depth of 75 metres with the nearest coastline (Scotland) located approximately 278 kilometres to the west thereof. The proposed development lies 7 kilometres west of the UK/Norway transboundary line.

The proposed development comprises a subsea drilling template and manifold with associated infrastructure and a pipeline connecting the Talbot field subsea facilities to the Judy platform. The Judy platform operated by Harbour Energy is located in Block 30/07 approximately 16 kilometres north of the Talbot field. Hydrocarbons produced from the Talbot field will be processed on the Judy platform before being transported back to the UK mainland at Teesside. Subsea installation activities are currently planned to commence at the Talbot field in 2023, with first development drilling operations currently planned from late 2022. First oil is expected in 2024.

Proposed activities

The Talbot Field Development is a new development and meets the extraction of oil and natural gas for commercial purposes thresholds listed in paragraph 1 of schedule 1 to the 2020 Regulations. The key elements of this project include the following:

(a) Three development wells will be drilled within a four-slot subsea drilling template with three subsea production systems installed within the drilling template.

(b) A four-slot subsea manifold will be installed using spools to connect the three subsea production systems. The Talbot subsea manifold will be tied-back to the existing Judy infrastructure via a subsea multiphase pipe-in-pipe production flowline and umbilical with an approximate length of 16 km. The umbilical will provide power, communications, hydraulic supply, methanol and other chemicals from the Judy platform to the Talbot subsea facilities.

(c) The Talbot production flowline will tie-in to the existing Joanne South 12” production pipeline (PL1000) at a point upstream of the Judy platform.

(d) Talbot produced fluids will comingle with Joanne and Judy field fluids on the Judy topsides, prior to entering the Judy-Joanne high-pressure production separator for onward processing on the Judy platform. At Judy, Talbot produced fluids will be separated into gas and liquids streams and
commingled with other J-Block area fields’ (Jade, Jasmine, Joanne and Judy) production.

(e) Talbot gas will be transported as part of a commingled stream from the Judy platform, via the below noted 20” gas export line PL977, to the CATS pipeline system and thereon to Teesside, UK for processing. Talbot liquids will be sent, via the below noted 24” oil export line PL978, to the Norpipe liquids pipeline and thereon to the Norsea terminal at Teesside, UK for processing.

(f) The host Judy platform is part of the J-Block area. The J-Block area is comprised of the following existing fields and facilities:

(i) the J-Block producing fields (comprised of the Jasmine, Joanne and Judy fields);
(ii) the Jade field;
(iii) the Judy platform, located in Block 30/7a and is bridge linked to the Judy riser platform;
(iv) the Joanne subsea manifold, located in Block 30/7a and is tied back to the Judy platform;
(v) the Jasmine Accommodation and Utility platform, located in Block 30/7a and is bridge linked to the Jasmine Wellhead platform, which in turn is tied back to the Judy platform;
(vi) the Jade platform, located in Block 30/2c Jade Field Area, is tied back to the Judy platform;
(vii) the 20” gas export line (PL977) which connects the Judy platform to the CATS pipeline system ‘T6 entry point’; and
(viii) the 24” oil export line (PL978) which connnects the Judy platform to the Norpipe oil pipeline at the Norpipe ‘main wye’ piece.

Timeline

The proposed timeline for the main project elements are:

(a) Development drilling from Q4 2022 (potentially Q3);
(b) Subsea infrastructure and pipelines laid 2023/2024; and
(c) First oil from Q3 2024
