Beehive 3D Seismic Survey – Contract Awarded
Friday 8 June 2018
Melbana Energy Limited advised that Polarcus has been awarded the contract to undertake the Beehive 3D Seismic Survey over the Beehive Prospect, which is one of the largest undrilled hydrocarbon structures in Australia.
The Beehive 3D Seismic Survey is being operated by Australian energy company Santos pursuant to an Operations Services Agreement and is fully funded by French major Total and Santos.
The Beehive 3D survey is expected to be commenced in July and completed before the end of August 2018. The survey is an typical 3D survey using methods and procedures similar to others conducted in Australian waters.
The survey acquisition area is approximately 600 km2 with a larger operational area around it to allow for vessel turns and testing of equipment. The operational area is located in the Joseph Bonaparte Gulf, approximately 225 km west-southwest from Darwin.
The acquisition of a new 3D seismic survey over Beehive will provide potential for further de-risking of the prospect and will facilitate consideration of a preferred location for the Beehive-1 exploration well.
WA-488-P Background
Commercial
Total and Santos have an option (exerciseable together or individually) to acquire a direct 80% participating interest in the permit in return for fully funding the costs of all activities until completion of the first well in the WA-488-P
permit. In the event of a commercial discovery, Melbana will repay carried funding from its share of cash flow from the Beehive field. Melbana will have no re-payment obligations for such carried funding in the event there is no commercial discovery and development in WA-488-P.
Technical
The Beehive prospect is potentially the largest undrilled hydrocarbon prospect in Australia. It is a Carboniferous age 180km2 isolated carbonate build up with 400m of mapped vertical relief, analogous to the giant Tengiz field in the Caspian
Basin. It is located in 40m water depth suitable for a jack up rig, within ~75km of shore and developable by either FPSO or pipeline to existing infrastructure. This play type is new and undrilled in the Bonaparte Basin with no wells having been drilled to this depth in the basin.
The carbonate reservoir is also interpreted to be the same age as the 2011 Ungani-1 oil discovery in the Canning basin, which tested at 1,600 bopd demonstrating a high quality reservoir. Beehive is a much larger build up than Ungani and has excellent access to the Lower Carboniferous source rock in adjacent depocentres.
Beehive is currently defined by a tight grid of 2D seismic data. Melbana has recently undertaken a reprocessing and inversion study of selected 2D seismic lines across Beehive with very encouraging results. The seismic inversion results
combined with the results of the reprocessing have enhanced the understanding of the Beehive reservoir and seal units. The acquisition of a new 3D seismic survey over Beehive will provide potential for further de-risking of the prospect and facilitate consideration of a preferred location for the Beehive-1 exploration well.
