The cost to drill a well is also much higher in real terms. It's especially expensive when you factor in all of the cost of deep-bore oil extraction, including the energy expended to do it and the amount of contaminated process water. Oil cracks when exposed to temperatures greater than about 300 F for an extended period of time. Dr. Bertha Alarcon Vargas, DDS, is a General Dentistry specialist practicing in Pomona, CA with 33 years of experience. Way out of my comfort zone and not trying to speak for DM, but cracking I think is an industry term for the breakdown of long petroleum hydrocarbon chains into smaller ones, I guess which occurs at higher temperatures. Rotten dinosaurs, honest! https://wattsupwiththat.com/2017/02/18/oil-where-did-it-come-from/. Its hard to believe there has been that much vertical movement in Earths surface (i.e., two miles subduction) over the last several hundred thousand to several hundred million years. Renewed assessment of some 22,000 cubic miles of deep sediments may carry over into the 21st Century. Sixty years ago, I worked as a floor hand on daylights when the worlds deepest well hit the bottom at 24,0002 feet in dark gray Hunton shale. Completion designs were optimized to successfully run an approximately 3,600-m open-hole completion, and the well was finished in approximately 70 days. I flamed out one engine in my F-4 at M1.6 (but very little indicated airspeed) at 65000ft on the TexArkana border. The trouble is the ambiguity of Measured Depth, which is really the length of the bore and only vaguely linked to actual depth. Key challenges included high torque and drag, wellbore positioning in a thin oil column, wellbore stability, long horizontal completions, and downhole tool telemetry. Those are remnants of the original pre-Oligocene land surface the Medicine Bow Peneplain. 1 rotary rig drill stem sheared, leaving 4,111 feet of pipe and the drill bit stuck downhole. This discovery has yet to be developed. This article takes us on a very interesting walk-about below ground. The deepest well ever drilled for any reason, the Kola Superdeep Borehole in Russia, only went down 40,230 feet. It has always been the case that some people take the newest research or hypothesis as more than just an idea or some guesswork, but instead see it as knowledge. Because it decomposes at or below that temp, to small chain alkanes, i.e. Ten wells in the Gulf of Mexico, drilled to true vertical depths greater than 20,000 have each produced more than 20 million barrels of oil. I know where oil does not come from, plants and dinosaurs at 40,000 feet. Water and halite (salt) are less dense than most rocks. But is the O-14 really 49,000 feet deep? Merchant of Record: A Media Solutions trading as Oilprice.com. Three of the project wells set ERD records for measured depth (MD). And its not like petroleum explorationists have had to look deeper for oil, well look wherever the technology allows us to go. After all, the purpose of Rosneft and Exxon was to pump oil, not see how far they can go into the ground: a feat in which serious challenges abound. Blasphemy! The measured depth (MD) of the worlds deepest oil well is over 40,000. Severe ones are typically 50,000. In 2008, an oil well was drilled to 40,318 feet in Qatar. Saint Helens, I say Saudia Arabia peninsula. Privacy Policy, Main Campus Its mind-boggling that you seem to think its clever. Despite drillers trying to avoid having expensive tools jammed deep in the well, accidents happened. For now, the deepest man-made hole in North America is the Bertha Rogers oil well in Oklahoma. Several sciencey websites also described it as the deepest oil well in the world and/or reposted the Fuel Fix infographic: And it generated hilarious comments like this: Remember folks: oil may be found 13 km deep but oil thats of biotic origin! And the ones over the ITCZ in the deep tropics can be 80,000. This is a Forest Gump breakthrough. Climate Activists Vow Huge Street Protests, Parliamentary Inquiry UK Green Jobs Narrative Unravelling, Wrong, Media and COP-27, Africa Is Not De-Carbonizing, Oil Exploration Is Expanding, Climate Czar John Kerry: We planet saviors had extraterrestrial influence., Surprise! As old ocean plates are subducted, sometimes islands, sediments, and anything else sitting on top of them is scraped off and accreted in the area adjacent to the subduction zone. As gas prices equate more closely to value, the nations needs may be met increasingly from this massive sedimentary basin, a focal point in drilling innovation and geological interpretation. (Hmmmshould I close with a sarc/tag or a smiley face?). Lindquist, Sandra J. The world's most viewed site on global warming and climate change, This eye-catching blog post was published in 2017 by Fuel Fighter. When controls on gas prices were lifted, Anadarko justified the faith and perseverance of The GHK Company and other operators who pioneered in deep drilling. After my first Physical Geology class in September 1976, I realized that I knew even less than I thought I did . However, valuable core samples were obtained and a lot was learned about deep sea drilling. She was born October 2, 1933 in English, West Virginia. The plate that North America sits on includes some sections that are very old, and some that are brand spanking new, and everything in between. Multiple sources say something to this effect: On November 26, 2005, Vijaypat Singhania set the world altitude record for highest hot-air-balloon flight, reaching 21,290 m (69,850 ft). Despite the record-setting Bertha Rogers and other deep wells in the Anadarko basin, the Permian basin currently There are some very interesting videos of large storms on you tube. Image from A Handbook of the Petroleum Industry, 1922. My quick Web search only turned up a reference to isotope dating Alberta oil sand deposits to 112 million years ago: https://phys.org/news/2005-05-world-age-oil.html . (2005). 1 well have been carried out: total organic carbon, Soxhlet extraction and silica gel chromatography, C15+ saturated and aromatic hydrocarbon gas chromatography and mass spectrometry, pyrolysis, kerogen analysis, X-ray diffraction and visual kerogen analysis. Am I still allowed to use a lighter to light my cigarette or do I need to go back to matches? And just as compression can uplift the land, at other times this compression may slacked, and the uplifted terrain then gets stretched out and drops. The operation repeated until the lowest piece was reached. Much of which wound up under the Gulf of Mexico as beautiful 30% porosity, 1,000 milidarcy permeability reservoir rock. . So, the deepest oil well in the world is not actually the worlds longest, and thats fine. My apologies to all. OH NO!!!! Funny story I knew nothing about geology when I decided to major in Earth Science. In terms of true vertical depth, the Bertha Rogers No 1 natural gas well in the Anadarko Basin used to be the deepest in the world, at over 31,400 feet. The well was halted because it struck molten sulfur. Its safe to assume that over these past ten years, the average well depth has only increased from there. This is the essence of the shale revolution.. Unfortunately, at this depth the. The drilling was started October 25, 1972 and it took Lone Star a little over a year and a half to reach 31,441 feet (9,583 m) on April 13, 1974. Here is a link to the site of a geologist who appears to have researched it carefully, and gives references, etc, including details of how one person giving a misattribution can lead to others repeating things that are not true, over a century later. Work continued until the project was abandoned in 1989 because the drill became stuck in rock at a little over 12km (almost 40,000ft or 8 miles) deep. The greater the hole angle, the bigger the difference. Science is the looking at and re-looking at theories and observations. If we assume the field has two target layers, and want to be reasonable, its better to plan on 16 wells per pad, wells drilled in four forks with four tines each, set in a skinny rectangular shape. In other words, the true vertical depth of the well is less than 1 km or 3,280 feet. And why is it. Long wells arent deep wells. Most of the sedimentary column is composed of thick, organic-rich shale. Perhaps the most effective method has been from studying earthquake or seismic waves as they move from one sensing station to another. [4], Oil-exploratory borehole in Washita County, Oklahoma, United States, "Summary of Deep Oil and Gas Wells and Reservoirs in the U.S.", "Oklahoma Corporation Commission completion report (form 1002A) dated September 3, 1974", https://en.wikipedia.org/w/index.php?title=Bertha_Rogers&oldid=1071960965, Buildings and structures in Washita County, Oklahoma, Creative Commons Attribution-ShareAlike License 3.0, This page was last edited on 15 February 2022, at 07:42. This process requires high temperatures and high pressure.[1]. They couldnt drill any deeper, the well was unstable They shouldnt have drilled that deep. IOW, whether or not such a material exists, and if it is occurring at a large volume, will not likely be settled by looking at sediments, but rather, IMO, by looking at where there are none. Notice where the two large areas with really thick sediments are: Gulf of Bengal and Mexican Gulf. I seem to have come in late and may be way down the totem pole here, but your fundamental problem is trying to evaluate or estimate local processes based on some global average.. The Chayvo wells were impressive accomplishments, Apr 22, 2014 Extended-reach drilling project from onshore rig surpasses previous Sakhalin campaigns, sets world records for MD, By Vishwas P. Gupta, ExxonMobil Development Co; Angel H.P. These are generally erosional surfaces that formed during the periods of uplift. A subject explored in some depth in my ebook The Arts of Truth. Organic geochemical analyses of fine-grained rocks from the 9.590 km Bertha Rogers No. Several different times for some of these rocks. In both cases, the crust overlies a mantle which can be detected because it transmits seismic waves at a distinctly higher velocity than does the crust, although there are also velocity variations within the crust itself. The Bakken shale members were deposited in a shallow marine environment under anoxic conditions. UmJeff, pretty sure DM just gave you the opposite of a slang definition. Against all odds and employing the latest 1970s technology, Ponder was able to retrieve the pipe sections and drill bit from 30,019 feet down, bringing operations back on line and enabling drilling to continue even deeper into Oklahomas Anadarko Basin, at a site about 12 miles west of Cordell. The typical person believes in PR.. Even deeper oil reservoirs have been discovered in the oil window, many of these will be coming on production over the next few years. And within that pile of sediment we find rocks holding organic material which didnt get eaten by bacteria when it fell to the bottom. I saw this after posting. Mud log from Well: BERTHA ROGERS 1 (2 LOGS) Operator: LONE STAR PRODUCING CO. hard to believe there has been that much vertical movement in Earths surface? Thanks for this precautionary tale of internet inaccuracies, illustrating succinctly why skepticism is an intrinsic part of a rational mind. In October 1982, the first hole reached 11,662 metres (38,261 ft), [5] and the second hole was started in January 1983 from a 9,300 metres (30,500 ft) depth of the first hole.
