The year 1921 marked the first drilling for oil at Dominguez Hill, on the northwest side of the Dominguez Rancho, site of the famous battle during the Mexican–American War called the Battle of Dominguez Rancho in 1846. The mineral rights to this property were owned by Carson Estate Company, the Hellman Family, the Dominguez Estate Company, and the Burnham Exploration Company of Frederick Russell Burnham. On September 7, 1923, Burnham Exploration partnering with Union Oil brought in the first producer on the site: Callender No. 1-A well at a depth of 4,068 feet (1,240 m) and 1,193 barrels per day (189.7 m3/d). Before long a number of refineries were up and running, with over 350 oil derricks, tank farms, and sprawling industrial complexes becoming a familiar part of the scenery. The principal leases were with Shell Oil Company and Union Oil of California and the first two wells were located west of Central Avenue and north of Victoria Street. Oil led to an increase in jobs in the community and a subsequent post-war population surge. An average of 300 barrels per day (48 m3/d) was produced from each of these wells through 1960.
