Hartshead Resources NL (ASX:HHR) has successfully completed a geophysical survey across the Anning and Somerville fields in the UK and interfield pipeline locations using GEOxyz’s Geo Ocean III vessel.
The Geo Ocean III is a 77-metre second-generation Dynamic Positioning Multi-Disciplined Offshore Survey Vessel, with specialist deep-push Cone Penetration Testing and vibro-coring capability.
The main objectives of the geophysical survey were to provide Hartshead with an interpretation of the seabed geomechanical and engineering conditions at the Anning and Somerville field locations, as well as an environmental baseline survey and habitat assessment as Hartshead advances towards First Gas.
The survey consisted of the following components:
- A detailed analogue and 2D high resolution survey over a 1,000 metre by 1,000 metre square box centred on the Anning and Somerville jacket locations;
- A 400 metre X 400 metre more detailed analogue survey to inform the exact emplacement of the Anning and Somerville jackets; and
- Onshore and offshore laboratory testing of seabed samples taken during the sampling operations. Onshore laboratory testing is still to be completed.
The results of the geophysical survey will form part of the Environmental Statement which is a key component of the Field Development Plan submission and is also required for the Platform Front-End Engineering Design jacket design verification.
