Overview

Hartshead is 100% owner and operator of License P2607 which is comprised of five blocks in Quads 48 and 49 on the United Kingdom Continental Shelf, in the Southern Gas Basin. The License contains multiple gas fields, some of which have been only partially developed.  There are also several exploration prospects.

Operations

The gas fields and prospects are divided into three phases for workstreams and operations:

PHASE I
Comprises the Somerville and Anning Gas Fields. Both fields have historic production, multiple well penetrations, 3D seismic coverage and combined remaining resources of 324 Bcf of gas (2C contingent resources). Hartshead has commenced field development planning work on these two fields and intends to define the development concept and gas export route by 2022, Take Final Investment Decision (FID) on the development in 2023 and achieve first gas in 2024.

PHASE II 
Comprises the Hodgkin and Lovelace Gas Fields.  Similarly, these field have production, well penetrations and 3D seismic coverage.  Seismic imaging requires improvement by reprocessing of the data in order to move these fields into development planning.  Hartshead aims to complete seismic reprocessing by the end of 2021, prior to having the contingent resources in Phase II audited and moving these fields forward for development.

PHASE III 
Hartshead’s exploration portfolio has undergone a study by Xodus Group which has generated a new prospect inventory totalling 14 prospects and leads with unrisked 2U Prospective Resources of 344 Bcf. Additional work is planned to de-risk the prospects further, economically evaluate and rank the prospects prior to the short-listing of a preferred prospect for initial well planning and drilling.

1Hartshead Resources management estimates.

2Prospective resources are estimated quantities of petroleum that may potentially be recovered by the application of a future development project(s) and relate to undiscovered accumulations. These prospective resources estimates have both an associated risk of discovery and a risk of development. Further exploration appraisal and evaluation is required to determine the existence of a significant quantity of potentially moveable hydrocarbons.

P2607 Production and Development Area

The multi-phased development of Hartshead’s Seaward Production License P2607 has the potential to serve the UK Government’s Bacton Energy Hub initiative and potentially provide material volumes of natural gas feedstock for blue hydrogen generation as well as providing future offshore infrastructure potentially for use in Carbon Capture & Storage and electrification projects.
