The discovery of the Glenn Pool Oil Reserve in 1905 brought the first major oil pipelines into Oklahoma, and instigated the first large scale oil boom in the state. Located near what was—at the time—the small town of Tulsa, Oklahoma, the resultant establishment of the oil fields in the area contributed greatly to the early growth and success of the city, as Tulsa became the petroleum and transportation center of the state, and the world. Several Creek Indian land allotment owners became millionaires; Oklahoma became the world's largest oil producer for years; and the area benefited from the generation of more wealth than the California Gold Rush and Nevada Silver Rush combined, as well as the increased investment capital and industrial infrastructure the boom brought with it. The town of Glenpool, Oklahoma was founded in 1906 as a direct result of the oil reserve's discovery.
History
Background
At the turn of the 20th century, the federal government dissolved tribal land claims of the Indian Territory in favor of a distribution of parcels to private owners. Robert Galbreath, a speculator and wildcatter, began prospecting in the area in 1901, and made an initial agreement that year with the recipient of one of these land allotments, Ida Glenn and her husband, Robert, to drill for oil on their farmland. Due to federal regulations of the time, however, it would be years before such drilling commenced. Following the change of oil leasing regulations affecting Native American land allotments enacted due to Oklahoma's pending statehood, Galbreath and a partner, Frank Chesley, finally began drilling on the Ida E. Glenn Number One drill-site in autumn of 1905.
Discovery
After almost giving up and conceding the well to probably be a "dry hole", Galbreath noticed signs of gas flow in early November and continued drilling. Due to the depth they had drilled by mid-November, the success of the well was doubtful. After seeing signs of oil in the well debris, however, the pair were encouraged and, once more, continued on. On November 22, at 5am, with the well deep into the layer of Bartlesville sandstone of the Boggy Formation, the two struck oil at a depth of. The "gusher" marked the discovery of what was eventually named the Glenn Pool Oil Reserve. The Ida E. Glenn Number One soon regularly produced 75–85 barrels of light, sweet crude oila day. Gilbreath, a veteran of the earlier Red Fork boom, wished to avoid the chaos which had followed that prior discovery and attempted to keep the drilling and subsequent discovery a secret, but to no avail. Several other speculators operating in the area noticed the activity at the farm. The area was immediately swarmed by oil and land speculators. Within a year, the approximately Glenn Pool held over 125 oil or gas producing wells.
Characteristics
Wildcat drilling took place over a wide area, which had the effect of quickly defining the core lay-out of the reserve, an area roughly four miles by two miles with a slope of about 40 feet per mile, and an average field thickness of 100 feet. The Glenn Pool Oil Reserve held an estimated 1 billion bbls of oil in place, with ultimate recoverable reserves of 400+ million bbls. The field grew from 80 acres to 8,000 acres during the first year. By 1907, natural flowing oil production ranged from to per year. Gas depletion caused by massive venting, however, decreased the gas pressure over the same period and the pumping for oil collection then became necessary. Total field production by 1907 exceeded, making Oklahoma that year the leading producer of oil, not only in the US, but any country in the world. The area experienced a huge economic boom. Prices for basic goods and services, however, soared in the area.
Consequences
Oil spills, due to a lack of storage facilities, were common early on. Often, open pits were dug and filled with the oil, forming huge "oil lakes" which sometimes escaped their banks and flooded the countryside. During thunderstorms, these "lakes" sometimes caught fire following lightning strikes. Due to this unclean method of storage, the product from the reserve often sold for as little as 25 cents per barrel. Oklahoma Natural Gas, Prairie Oil and Gas Company, Gulf Oil Company, and the Texas Company quickly built large-diameter pipelines into the area which by 1908 alleviated much of the infrastructure problems the rapid boom had caused. The Oklahoma oil boom created more wealth for speculators than the California gold rush and Colorado silver rush combined. Several of the Creek Nation land allotment owners in the vicinity became rich, almost overnight, and received regular royalty payments of over a million dollars a year following the discovery. One next-door neighbor of the Glenns, Thomas Gilcrease, became a multi-millionaire as a result of the oil production, and had 32 producing wells on his farm by 1917.
Aftermath
and J. Paul Getty both got their start during the Glenn Pool boom. The town of Glenpool, Oklahoma, was founded in 1906 as support for the fledgling oil industry in the area, and had over 500 inhabitants by 1910. Glenpool today calls itself "...the town that made Tulsa famous..." The Glenns sold their farm and moved to California. Galbreath and Chesley sold their interests in their original wells to an oilman, Charles Colcord, and continued looking for oil elsewhere. The original well, the Ida E. Pool #1, was abandoned and filled in 1964 by Texaco.
In the 21st century
As of 2019, the field has produced more than of oil. The Glenn Pool Oil Reserve boundaries have shifted about one mile to the west of the original perimeter. The reserve is still producing flow from legacy wells, although at a significantly lesser volume. Newer tight oil wells, especially since the introduction of "fracking" and "flooding" techniques for oil extraction, continue to regularly produce oil to this day.
