OKLAHOMA NATURAL GAS COMPANY BUILDING. The 1905 discovery of the world's richest oil field, the Glenn Pool, brought drastic changes to Tulsa. By 1912, buildings began appearing to house the lords of this new petroleum empire. In July, 1926, the Oklahoma Natural Gas Company moved from Oklahoma City to Tulsa, and construction began on this building which would become its corporate headquarters.
