Hartshead Resources NL and joint venture partner RockRose Energy Ltd have completed a geotechnical survey to determine seabed conditions of the Anning and Somerville gas fields.

SUITABILITY
Soils information from the cores will feed into the engineering design of platform anchor points and location of the jack-up drilling rig over the platforms.
Analysis results of material recovered from the 12-day survey are expected this quarter.
Hartshead said an initial review of the data indicated that both locations were suitable for platform and drilling rig operations.
The partners used Geoquip Marine to recover a total four rock cores, one 30-metre core and one 50-metre core from each location.
The Geoquip Seehorn, an 83-metre Class 2 dynamic positioning (DP2) multi-disciplined offshore survey vessel operated in “unseasonably poor sea conditions” without any problems.
