GASCO was incorporated in (1383) (1963) via the merger of National Gas Company in DAMMAM and its two branches in Riyadh and Jeddah together with Saudi manufacturing and Gas Company in Riyadh and its branches in DAMMAM. In the beginning of the seventies, many companies and small firms were incorporated to fill and distribute the gas. However, the sever inter-competition led to low services levels and irregular continuity of gas provision which required the government to interfere and decide to merge the incorporating company with National manufacturing and Gas Company (GASCO) by the end of (1395H) (1975).
