The deepest oil well in Oklahoma is Rogers Well.
The GHK Co. 1-27 Bertha Rogers hole or well was an oil-exploratory hole drilled in Washita County, Oklahoma in 1974, and was formerly the world's deepest hole until surpassed by the Kola Superdeep Borehole, dug by the former USSR.It took GHK two years to reach 31,441 feet (9,583 m), a depth of almost six miles. During drilling, the well encountered enormous pressure - almost 25,000 psi (172,369 kPa). No commercial hydrocarbons were found before drilling hit a molten sulfur deposit (which melted the drill bit), and the well was plugged and abandoned.[1]
The oil well drilled under the Oklahoma state capitol building was called the "Capitol Well." Drilled in the early 20th century, it became a notable feature due to the unexpected discovery of oil beneath the state capitol. The well was capped in 1931 but remains a part of Oklahoma's history and oil heritage.
Exxon Mobil drilled an oil well in Russia to a depth of 37,016 feet or over seven miles.
The deepest well in Wyoming is the "East Kirtley Well," which was drilled by the U.S. Geological Survey (USGS) in the early 1970s. It reaches a depth of approximately 14,500 feet and is located in the Powder River Basin. This well was part of a research project to study the geology and hydrology of the region.
No, the Pennsylvania oil fields came much earlier.

The first gas well was drilled in Canada in 1883
In 1866, Lyne T. Barret drilled Texas' first oil producing well. This well was drilled at Melrose in Nacogdoches County.
