Liao River oil field

The Liao River oil field, located in China's Liaoning province, is one of the country's largest onshore oil producers. It was initially developed in the late 1960s. The Liao River itself is a significant river system in southern Manchuria, draining a large plain area. While the river is not a major waterway due to silting at its mouth, the region is rich in mineral resources, including coal and iron ore, which contribute to the industrial strength of Liaoning province. The province also produces petroleum from oil shale, in addition to the output from the Liao River oil field.12
