The International Petroleum Exposition (IPE) was a specialized trade fair held in Tulsa, Oklahoma, at varying intervals from 1923 to 1979. Its main purposes were to display the latest oil industry technology, sell equipment and services, and to educate industry workers and the general public about the production of oil. History William G. Skelly, a leading Tulsa oilman and entrepreneur, is credited with conceiving the International Petroleum Exposition in 1923, while he was serving as president of the Tulsa Chamber of Commerce. He became president of the IPE in 1925 and held that position for the rest of his life. The first show was held in Tulsa on October 8–14, 1923. The city had been dubbed "Oil Capital of the World" and headquarters of many major oil companies and suppliers, so it seemed a logical choice. The venue was vacant ground downtown between Main to Cheyenne streets and from Archer to Cameron streets.

The Great Depression reduced the frequency of the event after 1930. Thereafter it was held in 1934, 1936, 1938 and 1940. It was completely suspended until 1948 because of World War II. When it reopened in 1948, over 300,000 people visited the show. However, there was competition from other events and the event had become very costly to produce, so the directors voted to hold the exhibition every five years. The next exposition was held in 1953. The Mid-Continent Supply Company commissioned the now-famous Golden Driller statue and displayed it at the entrance to the exhibition grounds. It drew so much favorable comment that the owner re-erected it in the next exposition in 1959. In 1966, all of
