The discovery of oil in Texas had a negative impact on Oklahoma, as the new oil fields in Texas were too close to those in Oklahoma.
With respect to Oklahoma, oil was discovered in Bartlesville and Burbank around 1897, but the initial discoveries did not create any expectation until the discovery of the great oil jet in Glenpool in 1905. The discovery of the Glenn deposit occurred when the production of the Gulf Coast declined rapidly, at which point operators were already eager to find new areas to drill. The increase of the perforation areas resulted in important discoveries in Cushing in 1912 and Healdton in 1913.
