Australia-based Empyrean Energy has started a 3D seismic survey on its 100%-owned Block 29/11, offshore China. 

Situated nearly 200km from Hong Kong, Block 29/11 comprises an area of around 1,800km² and is located at water depths ranging from 340m-600m.

Empyrean can conduct exploration under a geophysical survey agreement and also has a subsequent right to enter into a pre-negotiated production sharing contract with China National Offshore Oil Corporation (CNOOC).

Empyrean CEO Tom Kelly said: “We are very excited to make further progress in collaboration with CNOOC on Block 29/11.

“The block has two material prospects, Jade and Topaz, mapped on good quality 2D seismic data and the 3D seismic survey, which is now underway, will hopefully enable Empyrean to mature these exciting prospects for drilling.”

"The 3D seismic survey is now underway and will hopefully enable Empyrean to mature these exciting prospects for drilling."

The survey will be carried out by China Oilfield Services (COSL) and cover an area of approximately 580km².

It is expected to be completed in nearly 40 days.

After completion, the acquired data will be processed and interpreted, which will take another 90 days to be completed.

The survey will cover several prospects that were earlier identified on 2D seismic by Ameco Corporation, which is now part of BP, and CNOOC on Block 29/11.

These prospects include Jade and Topaz, which will benefit from the current 3D seismic programme.

The 3D seismic data for the recent discoveries located immediately to the West of Block 29/11 will also be acquired.
