“Wooden Walking Beam”

A wooden walking beam pumping unit in the Coalinga oil fields was one of the oldest and last remaining examples still in actual use there. Put into service in July 1918, it remained in continuous use until November 1979. Its initial production was 170 barrels per day, and its overall lifetime production reached 275,000 barrels of oil. Originally located about seven miles north of Coalinga, it was donated and relocated to this site by Chevron in September 1988. It honors the men and women of the oil industry whose work helped make the City of Coalinga a better place to live.
