INPEX Browse E&P Pty Ltd on behalf of the Bonaparte Carbon Capture and Storage Assessment Joint Operating Agreement participants was successfully awarded GHG assessment permit G-7-AP, located offshore in the Bonaparte Basin off northern Australia. The G-7-AP permit area is wholly located within Commonwealth waters to the north of the Joseph Bonaparte Gulf and approximately 100 km west of Darwin Harbour. The proposed GHG activity covered by this EP will consist of a pre-drill geophysical and geotechnical site survey. The pre-drill site survey activities are provisionally expected to be conducted in the second half of 2023. However, for contingency purposes this EP allows for the activities to occur anytime in the calendar years 2023 and 2024.

The pre-drill site survey, lasting up to approximately 30 days, will be undertaken at proposed well locations within the boundaries of the proposed project area, a small section of the broader GHG assessment permit where water depths range from approximately 75 m to 100 m.

The objective of the pre-drill site survey is to obtain a range of geophysical and geotechnical data for the proposed well locations to enable the identification of any geohazards and allow completion of the required assessments for the selection of a suitable mobile offshore drilling unit (MODU). The survey activities may be performed across an area of up to approximately 50 km2 centred on the proposed well locations and will include multibeam echo sounder, side-scan sonar, magnetometer, sub-bottom profiling, seabed grab sampling and one geotechnical borehole/or several piezo-cone penetrometer tests at each proposed well location. Operations will occur 24 hours a day.
