State-run China National Offshore Oil Corp. (CNOOC) issued an exploration tender inviting foreign oil companies to bid for 33 oil and gas blocks.
The gas blocks cover an area of 126,108sq km off east and southern China.
CNOOC says all qualified oil companies may apply for data room visit and data purchase. Data room locations are in Shanghai, Guangzhou and Zhanjiang.
Data rooms will close on 31 December and bidding closes on 30 April 2015.
Blocks are available in the East China Sea basin, South Yellow Sea basin, east Pearl River Mouth basin, Beibugulf basin, Yinggehai basin and Qiong Dongnan basin.
The largest amount of licenses available in one basin is 17 licenses in the east Pearl Mouth basin with water depths ranging from 50m to 3000m. A majority of which have 2D and/or 3D seismic surveys acquired.
The Qiong Dongnan basin has a total of five licenses with water depths ranging from 70m to 2500m. All have 2D seismic surveys and only four have 3D seismic surveys acquired.
Both the East China Sea and South Yellow Sea basins have four licenses. All have 2D seismic surveys and are shallow-water licenses ranging from 15m to 100m in water depth.
The Beibugulf has two licenses ranging from 40m to 80m water depth and the Yinggehai basin has one license at 70m to 90m water depth.
CNOOC began drilling offshore China this week in their operated Beibu Gulf Block 22/12 at the WZ 12-10-1 exploration well. The well is one of two exploration wells in the block. The drilling program in Beibu follows previous exploration discoveries and successful development of the WZ 6-12 and WZ 12-8W fields in 2012 and 2013, which have produced over 6MMbbl.
