In 1930, about 20 miles from where I am, the Daisy Bradford #3 was drilled at a depth of 1530 feet. The Daisy Bradford is still in production, almost 80 years later.
Daisy Bradford No. 3, the rank wildcat well that discovered the giant East Texas oil field which, with an estimated recovery of 6 billion barrels of oil, became the largest oil field in the world at that time.
Prior to this, the Beaumont area (Spindletop) brought in heavy production in 1901.
The Lucas geyser, found at a depth of 1,139 feet, blew a stream of oil over 100 feet high until it was capped nine days later and flowed an estimated 100,000 barrels a day.
That's two areas, about 200 miles apart, that were producing at 1500 feet or less.
When the initial flow from Spindletop dwindled from overproduction, a deeper probe was made.
on November 13, 1925, the Yount-Lee Oil Company brought in a flank well drilled to 5,400 feet.
Things still weren't finished for Spindletop as it went even deeper.
In 1963-66 even deeper oil production was achieved with an average depth of 9,000 feet.
To put that into perspective, the production began about 1/4 mile deep, then it went down to about 1.0 mile deep and finally to about 1.8 miles deep.
Locally, we've experienced much the same in the East Texas field. The shallow oil and gas production has been pushed deeper, while the shallow lignite (a low grade coal that's isn't too much more than black dirt) is also being exploited, like this Texas Utility dragline in operation.
We are currently receiving royalties from the Cotton Valley formation in the Carthage field similar to this report.
That's million cubic feet per day in production.
Devon Energy Production Company has completed the Fender, H.R. Well No. 19 in the Carthage Field. This well was completed to a depth of 9,591-feet 5.7 miles southwest from Carthage. This well showed a potential of 1.591 million cubic feet of gas when gauged on an adjustable choke. Production is in the Cotton Valley formation.
The latest "find" is the Bossier/Haynesville shale formation or Barnett shale around the Dallas area, that's even deeper than the Cotton Valley, like in this report.
XTO Energy Inc. has completed the Harris-Drummond Gas Unit II Well No. 3H in the Carthage, North Field. This well is located 6.9 miles southeast of DeBerry with a depth of 15,500-feet. The well was gauged on a 16/64-inch choke and showed a potential of 3.682 million cubic feet of gas. Production is in the Bossier Shale formation.
So, we're down to 15,000 feet now, almost 3 miles deep or 10 times as deep as the Daisy Bradford #3, and still finding gas and liquid hydrocarbons. While the formations do undulate, which makes their depth vary, the depth is ever increasing.
With the increase in depth over wide areas, the layering at vastly differing depths would seem to indicate there is no connection to it being a "fossil fuel" or the Flood. It's quite possible it's still being made today.
Although accidents and hurricane damage to infrastructure are often to blame for oil spills and the resulting pollution in coastal Gulf of Mexico waters, natural seepage from the ocean floor introduces a significant amount of oil to ocean environments as well. source
Using a technique they developed in the early 1990s to help explore for oil in the deep ocean, Earth Satellite Corporation scientists found that there are over 600 different areas where oil oozes from rocks underlying the Gulf of Mexico. The oil bubbles up from a cracks in ocean bottom sediments and spreads out with the wind to an area covering about 4 square miles. source
Recent measurements in a major oil field show "that the fluids were changing over time; that very light oil and gas were being injected from below, even as the producing [oil pumping] was going on," said chemical oceanographer Mahlon "Chuck" Kennicutt. "They are refilling as we speak. But whether this is a worldwide phenomenon, we don't know."
Kennicutt, a faculty member at Texas A&M University, said it is now clear that gas and oil are coming into the known reservoirs very rapidly in terms of geologic time. The inflow of new gas, and some oil, has been detectable in as little as three to 10 years. In the past, it was not suspected that oil fields can refill because it was assumed the oil formed in place, or nearby, rather than far below. source
