In December 1963, an industrial oil flow was discovered in Huanghua County, Hebei Province. The Ministry of Petroleum of the People's Republic of China decided to organize the North China Oil Campaign. On December 20, 1964, a blowout occurred in Gang 5 well, announcing the birth of Dagang Oilfield. Following the Gang 5 well, the Gang 7 well and the Gang 3 well also began to produce oil, with daily oil production exceeding hundreds of tons. Subsequently, three oil fields in the east, middle and west of Dagang were discovered one after another. In 1999, the Dagang Oilfield Branch of PetroChina was established.
