Original oil and gas trade magazine vintage ad for CHRISTENSEN DIAMOND PRODUCTS COMPANY. General offices were located at 1937 South Second West, Salt Lake City, UT. Turbo-Bits proving successful! The introduction of the turbodrill has provided the industry with a tool of great promise, However, the turbo demands a bit that can absorb and effectively utilize its increased downhole power, can withstand high rotational speeds and increased fluid volumes. This unique 1959 old oilfield petroleum drilling industry equipment magazine advertisement would display beautifully matted and framed. Wonderful graphics.
