Mosman confirms CGG Aviation for NT contract

Mosman Oil and Gas has awarded the contract for an airborne gravity and gradiometry survey over EP145 in the Amadeus Basin, Northern Territory, to CGG Aviation.

The acquisition of data is planned for mid-June and is a step in the exploration program for EP145.

The company advised that this is the first time data will be acquired across the while permit in order to identify where to focus the seismic program to enable Mosman to identify a drilling prospect.

The survey operation is subject to Northern Territory Government approval, which was applied for in May.

The gravity survey will provide valuable data regarding the subsurface geology across the entire 818km2 permit area.

Current subsurface seismic data is limited to the northwest and central part of the permit and existing regional gravity data is too sparse to provide sufficient detail of the complex salt related structures which have been identified as hydrocarbon and helium leads within the permit.

Mosman outlined that the survey will be acquired using the high resolution Falcon Airborne Gravity Gradiometry System which has the ability to image salt and subsalt geometry across a range of depths.

The technique measures the density contrast of the different rock layers with a higher level of resolution and sensitivity than standard gravity tools, improving confidence in the interpretation of high density and gravity features including salt related structures.

The Falcon system has been used to successfully interpret drill targets across a variety of geological settings around the world including the Canning Basin, Western Australia.

Mosman chairman John Barr said the company is delight to have awarded the contract.

“This allows Mosman to be able to use the Falcon gravity and gradiometry data to assist with refinement of the 2D seismic programme in order to focus on potential drill targets in the permit,” he said.
