Highlights: 

• Adoption of a new field and prospect naming convention chosen to celebrate exceptional  British and Irish women in science, technology, engineering and medicine
• Commencement of the Phase II subsurface work programme covering the Hodgkin (formerly Audrey) and Lovelace (formerly Tethys) field developments targeting completion in Q2 2022   
• Receipt  of  pre‐stack  depth  processed  3D  seismic  dataset  covering Hodgkin and Lovelace fields from the previous Operator, Spirit Energy, achieves time and cost savings, associated  with the development of the Phase II assets
• Phase II workstreams will generate revised in place gas volumes, recoverable 2C contingent  resources and production profiles for the Hodgkin and Lovelace fields
• On completion of the Phase II workstreams, revised 2C Contingent Resources on Hodgkin  and Lovelace will be independently audited as part of an updated Competent Persons Report  (CPR) covering the Phase I and Phase II assets.   

Hartshead Resources today announced the commencement of the Phase II subsurface work programme covering the Hodgkin (block 48/15c) and Lovelace (block 49/6c, 49/11c) field developments as part of the multi‐phased development of Seaward Production License P2607 in the UK Southern Gas Basin. 

The Company recently received the pre‐stack depth processed Annabel, Audrey an Audrey Extension 3D seismic datasets from the previous Operator of the Audrey Field, Spirit  Energy. This data  was reprocessed between 2011 and 2013, incorporating six separate 3D seismic surveys and covers both the Hodgkin and Lovelace Fields.  

This new data enables the Company to finalised a new work programme & budget  for the Phase II subsurface workstreams, targeting completion in Q2 2022. The Phase II workstreams will encompass the construction of a new geological and geophysical database, detailed interpretation of the new 3D seismic data, petrophysical analysis and reservoir engineering to deliver revised in place gas volumes, recoverable 2C contingent resources and production profiles for both the Hodgkin and Lovelace gas fields.  

The Hodgkin and Lovelace fields are located in the north‐west part of License P2607 and are currently  estimated to contain a combined 139(1) Bcf of 2C Contingent Resources. Following completion the Phase II work programme contingent resources at Hodgkin and Lovelace will be independently audited and the results compiled and announced as part of an updated Competent Persons Report (CPR) covering both the Phase I and Phase II assets.    

Once revised production forecasts for Hodgkin and Lovelace are available a decision will be made to proceed with field development planning for the two fields. This will present the opportunity to utilise the Phase I infrastructure to monetise the Phase II gas production.  

Transmission of the Phase II gas flow stream through the Phase I pipeline may lead to a potentially enhanced economic performance of the Hodgkin and Lovelace fields given the upfront investment in Phase I infrastructure.   

HODGKIN FIELD 

The Hodgkin field has historically produced 26 Bcf of gas from a single well, is currently estimated to contain 100 Bcf(1) of 2C Contingent Resources and is an extension of the Audrey field. This estimate of in place and recoverable gas volumes and productivity of Hodgkin is already proven by previous drilling and production.  

Seismic imaging of the reservoir at Hodgkin is challenging in places due to a complex overburden containing  the Audrey Salt Wall. The recently received pre‐stacked depth migrated  (PSDM) seismic data significantly improves the seismic image, removing many of the effects of the overburden, and will improve the mapping of the Hodgkin gas field to generate a new structural map. This will assist with improved gas‐in‐place estimates and development well positioning.  

Petrophysical analysis of Hodgkin and Audrey wells plus analysis of production and pressure data from the historic field production will greatly improve confidence in production forecasts and contingent resource estimates for the field. 

LOVELACE FIELD  

The Lovelace field is an undrilled extension of the Tethys gas field and is currently estimated to contain 39 Bcf(1) of 2C contingent resources which is planned to be development via a single production well. This field is also covered by the PSDM seismic data and revised production forecasts and contingent resources will be part of the Phase II workscope.

Chris Lewis, CEO, commented, 
“I am delighted with the names of our Phase I and Phase II gas fields and how  this reflects our commitment  to diversity and inclusion as an organisation and support of women in science, technology, engineering and medicine. Also, I would like to thank Spirit Energy for their assistance in providing a large volume of 3D seismic data to Hartshead. This has, undoubtably, saved time, money and effort in the development of our Phase II assets. I look forward to the results of the Phase II work and being able to provide an update in due course”.
