China
China has made significant strides in onshore oil exploration in recent years, with a focus on increasing domestic oil production to reduce its reliance on imports. The country's onshore oil reserves are primarily located in the Ordos Basin in the north, the Tarim Basin in the northwest, and the Bohai Bay Basin in the east. The most notable onshore oil fields include the Daqing Oilfield, which is one of the largest onshore oilfields in China, and the Shengli Oilfield, which is one of the largest offshore oilfields in the world. The Chinese government has implemented various initiatives to boost onshore oil production, including increased investment in exploration and development, as well as the use of advanced technologies such as 3D seismic imaging and horizontal drilling. As a result, China's onshore oil production has been steadily increasing, with output reaching a record high in 2020.
