Erle Palmer Halliburton was an American businessman specializing in oil field services.

After his honorable discharge in 1915, he headed for the oilfields of California, where he was able to apply techniques analogous to the technology with which he had worked in the Navy.

Halliburton later quipped that getting hired and getting fired by the Perkins Oil Well Cementing Company were the two best opportunities he had ever received.

[2] Halliburton then moved to Duncan, Oklahoma, where he invented, perfected, and patented a new method of oil well cementing.

According to one of the inscriptions on the pictured monument, Halliburton's method "isolates the various downhole zones, guards against a collapse of the casing and permits control of the well during its producing life."
