Original oil and gas trade magazine vintage ad for HALLIBURTON OIL WELL CEMENTING COMPANY. Main office was located in Duncan, OK. Halliburtons Vis-O-Frac Treatment. Converts low cost crudes into highly effective fracturing fluids. Lease crudes are chemically converted into low-cost fracturing fluids with Halliburtons Vis-O-Frac process, and all types of oil and gas producing formations have been effectively fractured with this treatment. This unique 1957 old oilfield petroleum drilling magazine advertisement would display beautifully matted and framed. Nice graphics.
