The East China Sea Basin is located on the shelf of the East China Sea with an area of about 250,000 square kilometers. It is the largest sedimentary basin offshore China (see photo), which is equivalent to four sedimentary basins in the Pearl River Estuary, Qiongdongnan, Yinggehai and Beibu Gulf in the northern part of South China Sea Sum. Here, oil and gas exploration is still in the stage of regional census. In the recent five years, a large-scale geophysical survey and drilling work has been carried out with the Bureau of Geology and Mineral Resources, Ministry of Geology and Mineral Resources and the former Offshore Petroleum Exploration Bureau of the Ministry of Petroleum Industry.
