Activity Description

Esso plans to continue to undertake Geophysical and Geotechnical investigations within existing production licence and retention lease areas. The investigations will consist of a number of individual campaigns to inform a number of prospective future activities in the Gippsland basin. These include: • development of new and existing gas fields • development around existing facilities • plug and abandonment • decommissioning; and • drilling. The activity will take place in Production Licences VIC/L01, VIC/RL1, VIC/L02, VIC/L03, VIC/L04, VIC/L05, VIC/L06, VIC/L07, VIC/L08, VIC/L09, VIC/L10, VIC/L11, VIC/L13, VIC/L14, VIC/L15, VIC/L16, VIC/L17, VIC/L18, VIC/L19, VIC/L20, and VIC/L25, located in the Gippsland Basin of the eastern Bass Strait. The proposed seabed surveys will be carried out during the life of the EP 5 years from the date of accepted EP. The G&G surveys are estimated to take up to a maximum of 180 days per year. Geophysical investigations are proposed to be undertaken using the following conventional techniques: • single beam echo sounder (SBES) • multi beam echo sounder (MBES) • side scan sonar (SSS) • sub bottom profiler (SBP) including Ultra high resolution (UHR) • magnetometer • sound velocity profiler (SVP) • pipe tracking system (PTS) • subsea photogrammetry. Geotechnical sampling proposed are: • Cone penetrometer testing (CPT) • Drop coring or vibrocore • Borehole sampling/coring • In situ thermal conductivity tests In addition, seabed imagery, and sediment and water samples will be undertaken at representative locations to collect baseline data. Seismic surveys are not included in the activity scope.
