bertha rogers well

However, if hydrocarbons (both gas and liquid) tend to percolate/migrate upward against gravity, as others have mentioned, one wonders what mechanism/geology is so effective at preventing gas diffusion for as long as 400 million years? The geothermal gradient is highly variable. More than 500 of her poems have been published in literary journals, and she had received eight nominations for the Pushcart Prize. Dating methods include vitranite reflectance and 13C isotope ratios in diamondoids (which arent diamonds). That person has a low chance of ever getting themselves straightened out. In order to get their single drill hole down as far as they did, the Soviets had to resort to experimental methods. Union is nationally recognized for Christ-centered academic excellence and exceptional value. In many place around the globe oil is found below land surfaces that currently are hundreds to thousands of feet ABOVE sea level. Downstream from the Himalaya and the Rockies respectively. The well was halted because it struck molten sulfur. The dinosaurs must have met the Methane coming on the way up. Petroleum-like substances have been associated with hydrothermal vents in basins with thick organic-rich sediments. Interestingly, Fourier doesnt even mention hothouses or greenhouses, and actually stated that in order for the atmosphere to be anything like the glass of a hotbox, such as the experimental aparatus of de Saussure (1779), the air would have to solidify while conserving its optical properties (Fourier, 1827, p. 586; Fourier, 1824, translated by Burgess, 1837, pp. Bookstore No commercial hydrocarbons were found before drilling hit a molten sulfur deposit, which solidified around the drill string, causing the drill pipe to twist-off and a loss of the bottom-hole assembly. Most of the seafloor has a thin veneer of sediment But, the depocenters have enormously thick sedimentary sequences. I was going to check on those others, figuring they may all be wrong. Science these days seems to be more and more filled with impressive illustrations and animations which at bottom are not based on real data directly and are heavily influenced by someones opinion about how things work. Water and halite (salt) are less dense than most rocks. It is not oil or gas that is being sought with the Kola well, but an understanding of the nature of the earth's crust. The Earth's crust is broken into many smaller plates that slide very slowly over a more mobile or 'plastic' material called the asthenosphere. I will cease asking questions on this subject matter in deference to those I have obviously upset. Any one well has a very limited area of influence. ROBERT ALEXANDER HEFNER III, PETROLEUM INDUSTRY. Metal and inorganic surfaces can act catalytically, however. I note that the NOAA graphic of total sedimentation across Earths oceans is generally consistent with the data presented in the Peter Olson, et. 1 (Anardarko basin, Oklahoma, U.S.)* . I think Ill stop (commenting, not reading). After my first Physical Geology class in September 1976, I realized that I knew even less than I thought I did . Heres what Wikipedia says about Lawn Chair Larry. Oklahoma extracts the brine from a 9,800 feet (3,000 m) deep well. On 6 June 1979, the world depth record held by the Bertha Rogers hole in Washita County, Oklahoma, United States, at 9,583 meters (31,440 ft), was broken. That is the current record for a depth reached by humans. 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. There is also a record-breaker in terms of water depth: Maersk Drillings Raya-1 well offshore Uruguay was drilled in water depths of 3,400 meters or 11,156 feet. I worked on a development plan which required platforms with two drilling rigs sitting over 28 well bays each. Volcanoes deposited material on top of the crust, and also sometimes magma welled up but never broke the surface, and the magma cooled deep underground. The Tiber wells depth - true vertical depth - was more than 35,000 feet. The project cost over $100 million, which is about $2500 per foot. The process whereby ocean crustand the sediments sitting on top of them, or sediments that formed in places called inland seaswind up as the tops of mountains or halfway to the bottom of the Grand Canyon or anywhere else that is not the top of a mountain, is called uplift, not subduction. Was it pure sulfur? paper that I referenced above. It led to far deeper wells. What other types of materials might exist unexpectedly way down there? For anyone who never heard the incredible story of Ewa Wisnierska: Wow! https://www.google.com/url?sa=t&source=web&rct=j&url=https://m.youtube.com/watch%3Fv%3DFHtvDA0W34I&ved=2ahUKEwj73Ky8897hAhVDmIsKHbfZCfAQwqsBMAB6BAgGEAU&usg=AOvVaw3fMJb2nOZzbkk6cRpI1kqX. Sometimes many inches, sometimes barely moving, or just sitting mostly still, or spinning. That guy was brave. The Wikipedia on that borehole says that the sulfur melted the drill bit, and that is why they stopped? Measured depth is basically how far the well was drilled. The deepest hole within the U.S. is the Bertha Rogers gas well in Oklahoma at 32,000 feet (6 miles) deep. In this manner, they were able to eliminate rotation of the entire drill string above. Dinosaur carcasses are (rarely) found in marine sedimentary deposits (including shales), presumably after coming down a river or possibly washed out to sea by hurricanes or tsunamis. UmJeff, pretty sure DM just gave you the opposite of a slang definition. The main target depth was set at 15000 m. On 6 June 1979, the world depth record held by the . 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. The notion I have of oil has to do with sedimentation, not subduction. Everest and all mountain ranges with elevations of 2 miles above sea level to the areal extent of all oil fields with producing layers greater than 2 miles below sea level? (2000). On Russia's Kola Peninsula, near the Norwegian border at about the same latitude as Prudhoe Bay, the Soviets have been drilling a well since 1970. As an Amazon Associate, AOGHS earns a commission from qualifying purchases. The first oil well drilled in Texas in 1866 was a little over 100 feet deep: the No 1 Isaac C. Skillern struck oil at a depth that, from todays perspective, is ridiculously shallow. At this time development was deferred. It required about eight hours for bottom hole cuttings to reach the surface almost six miles above. Become an AOGHS supporting member and help maintain this energy education website and expand historical research. Merchant of Record: A Media Solutions trading as Oilprice.com. The measured depth (MD) of the worlds deepest oil well is over 40,000. It was a borehole that reached 31,400 feet, or nearly six miles, into the Earth. Since then, numerous gas wells have been drilled there below the twenty thousand foot range, including the Lone Star Bertha Rogers in Beckham County. Did it ever pay out the cost of drilling to 31,000? 1 in Washita County, drilled in 1971 to 31,441 feet, was then the worlds deepest well. It is now over 40,000 feet deep, making it the deepest hole on earth (the previous record holder was the Bertha Rogers well in Oklahoma--a gas well stopped at 32,000 feet when it struck molten sulfur). Walker Ridge 758 Chevron #1 is the deepest active oil producer in the Gulf of Mexico; drilled to a true vertical depth (TVD) of 28,497 (8.7 km) in a water depth of 6,959. The shallow water Lower Tertiary gas discovery at Davy Jones is well out of the oil window, but in the gas window and has never produced anything. One of the cable tool sections would eventually yield, unscrew, and be removed.. The longest well, Z-42, established records for MD (12,700 m) and horizontal reach (11,739 m). Doesnt the sulfur in matches contribute to acid rain? Those that hit one of the deep productive zones had an extremely long production life for a gas well, and still had all the remaining upper zones remaining to complete in the future. It was picked up by Internet news sites like Business Insider, The worlds deepest oil well is over 40,000 feet deep Jeff Desjardins, Visual Capitalist Mar. The depths on the chart are approximations based on a generalized geothermal gradient. 1 well was the deepest in the United States. Because it decomposes at or below that temp, to small chain alkanes, i.e. That record, of course, is over 16,000 feet. A spud was then employed. I dont give energy back to the gas & electric companies in exchange for them being nice enough to heat and light my home. The term fishing came from early percussion drilling using cable-tools. Each are well described, extensively supported, and largely uncontroversial, at least as regards the big picture. In addition to the important bearing that this discovery has on the general geophysical sciences, there is a potential economic impact. That is mostly Mississippi/Missouri. Octane isnt even oil. https://en.wikipedia.org/wiki/Kola_Superdeep_Borehole, http://www.nationalacademies.org/history/mohole/. 2745 Hacks Cross Road Not actual cracking. Seriously, the Russians were right all along, oil is obviously of abiotic nature. The Bakken is Devonian. Memphis, TN 38104 We actually do know where oil comes from. It was completed in a Lower Tertiary Wilcox sandstone (26,831 27,385). Notice where the two large areas with really thick sediments are: Gulf of Bengal and Mexican Gulf. The layered zones made it practical to dill these very deep wells as a field. Shells Perdido spar on Alaminos Canyon 857 in 7,835 WD has no slots. One of the reasons why places like the Gulf of Mexico exist, and have such large amounts of sediment and such old sedimentary rock in place,is because they have, for various reasons, never been subducted. Related: Forget Tesla, This Is The Most Impressive Electric Vehicle Of The Year. Many holes have been dug for both research and commercial purposes. Rosneft states it on its website, in a press release on the completion of O-14, that the total depth of the well, including the vertical and the directional section, is 15 km, of which the non-vertical section extends 14.13 km, or 46,900 feet. John L. Grandin attempted to recover a lost drill bit at his 1859 well near Tidioute, Pennsylvania. It conducts heat away from the substrata toward the surface. I suppose molten sulfur would count as economic basement. Amazing would be more aptif only this depth were true. It was completed as as gas well in the Granite Wash at about 13,000. And Im not even factoring in the compaction of the sediments as they pile up. Looking a little more closely, it seems perhaps Fuel Fighter, or whoever made that graphic, may have not known the difference between feet and meters. In rotary drilling, the only tools ordinarily used in the well are the drill pipe and bits, Day noted, adding that the rotary fishing tools, were comparatively free from the complexities of cable-tool work.. Its mind-boggling that you seem to think its clever. The materials provided on this Web site are for informational and educational purposes only and are not intended to provide tax, legal, or investment advice. Using nails and wax, an impression block helps determine what is stuck downhole. Contact Us The was an even more of a science experiment drilled south of Sayre towards Magnum & Granite. There is only one possible solution to make the paradoxes go away. 4,892 views Dec 9, 2020 The deepest borehole in the world. wildcat well to a depth of 31,441 feet (9,583 m) in Beckham County, Okla., in the Anadarko basin. Wells drilled here have been among the world's deepest. [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. Kenny A. Franks, The Oklahoma Petroleum Industry (Norman: University of Oklahoma Press, 1980). Once all well fishing tools failed, a final resort was a whipstock, which allowed the bit to angle off and actually bypass the fish to leave the operator with a deviated hole. Recommended Reading:History Of Oil Well Drilling(2007); The Prize: The Epic Quest for Oil, Money & Power (1991);The Extraction State, A History of Natural Gas in America(2021). The oil migrated upward from deeper Mesozoic and Lower Tertiary source rocks. I do remember reading about the deepest hole ever drilled, and how it turned out to be a huge waste of money, but not sure if this was the same project? Bertha Rogers Bertha Mae Rogers, 82, of Carlisle, formerly of Shippensburg, passed away Wednesday, July 20, 2016 in the Select Specialty Hospital at Camp Hill. It was drilled for research purposes beginning in 1970. Or at least, such is my understanding, in a nutshell. I have been in the real estate industry for over 15 years and I love being able to find the perfect home for any family. It would depend on how the molten sulfur was sampled. Its currently producing about 60,000 bbl/d and 110 mmcf/d (~78,000 BOE/d) from 8 wells And its still ramping up. Pretty much. In both, its splitting molecular bonds.. I think the question is not subduction, but the vertical extent of sedimentation, no? The sediments wound up at the bottom of the inland sea. It was a science project in response to the US Project Mohole. WWS, what you describe as the subduction of the Pacific plate is actually a much more complicated situation, involving a series of plates and faults and features being subducted, and also accreted onto, and sliding past, the North American plate. Well, if you say Mt. Couldnt have been an actual Darwin Award, which requires that the stunt kill you without progeny. 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! 74-89% of retail investor accounts lose money. . Completion designs were optimized to successfully run an approximately 3,600-m open-hole completion, and the well was finished in approximately 70 days. Actually there might theoretically be a little bit of ex-dinosaur in oil. Organic geochemical analyses of fine-grained rocks from the 9.590 km Bertha Rogers No. Saint Helens, I say Saudia Arabia peninsula. We had a five man crew. Please, Saudi Aramco Is Very Optimistic About Oil Demand, Saudi Arabia Aims To Become The Worlds Fastest-Growing Economy In 2023, U.S. Natural Gas Demand Set To Climb As Cold Weather Closes In, Bullish Catalysts Are Mounting For Copper, Central Asias Glaciers Are Melting At Astonishing Rates, Gas Flowing To Freeport LNG, Restart Timeframe Unchanged, U.S. Defenders of biotic origin oil are not worried about how dinosaur remains got to more than 5 miles below the Earths surface. I doubt there will ever be a day that no new textbooks are needed. The Sierra Nevada contains some of these types of features, which subsequent erosion brought to the surface. The raw material in Cretaceous source rocks was deposited during the Cretaceous Period. The average bottom hole temperature of those ten 20 million barrel producers was 197F. Places like the Great Salt Lake (the remains of a huge place called Lake Bonneville) are depositing a type of sediment called an evaporite at the margins and bottoms. Those are source rocks, not reservoir rocks. My name is Bertha Martinez-Carmona and I am here to help you find YOUR home and listen to your needs to best assist you! Digging a hole straight down would seem to be the most effective way to study the Earths interior. IOW, when someone finds oil where no sediments exist, then I think the idea will have some legs. He launched from downtown Bombay, India, and landed 240 km (150 mi) south in Panchale.. I think this illustrates very well part of the AGM problem that skeptiks are dealing with because when it is pointed out to a believer that empirical data totally undermines any point they try to make they are not concerned in the least. The bull wheel, driven by the wells steam-powered drilling engine, exerted a tremendous strain on the assembled poles. Giving to Union Surface Temperature Record Reliable? It is really easy to look up the geologic history of any particular place. Helium is recovered from produced natural gas as a byproduct. On the rig floor, fishing tools had to be lowered by a line into the well, armed at their end with spears, clamps and hooks. It was a beauty. If this was the only time anyone drilled so deep and that is what happened, and it was unexpected or a unique finding, does that not make it a very interesting question, re what the hell else is down there that no one knows about or predicted? Keep up with Union University events on campus and student, faculty and alumni engagement around the world. 2022 Geophysical Institute, University of Alaska Fairbanks. In June 6, 1979, one of the boreholes in Kola, SG-3, took the record. It would be nice if there was a filter to block the word abiotic, or at least the words dinosaur and maybe Gold from the comments in Daves posts. http://old.fai.org/news/personalities/35338-judyleden, While not a hot air balloon, Joe Kittinger jumped out of a balloon gondola at 102,800, http://www.airforcemag.com/MagazineArchive/Pages/2014/August 2014/Kittinger.aspx, Yeah, but did she do it with no oxygen or even a heavy coat? While they do not appear to based on directly dating the hydrocarbons, the geological strata referenced and those strata in which hydrocarbons have NOT been found in any significant quantity does, to me, seem to rule out the abiotic oil theory on the following grounds: For example here is a cell dynamics video I randomly selected. Funny how the same people do not object to the blight of windmills covering the landscape or the concrete pads they are sited on being dug into pristine terrain. Searching for oil was less an earth science and more an art in the exploration and production industrys earliest days. (Hmmmshould I close with a sarc/tag or a smiley face?). Obituary. And within that pile of sediment we find rocks holding organic material which didnt get eaten by bacteria when it fell to the bottom. Consider sandstone reservoirs vs chalk reservoirs. down the sun. The technology for mining the depths at which the solutions occur, however, is not yet available. Perhaps the most effective method has been from studying earthquake or seismic waves as they move from one sensing station to another. The well at Chayvo is, according to the infographic, also deeper than the world record for a hot-air balloon flight: 21,000 feet. It had to do with the original of the term greenhouse effect, and the various attributions thereof. & Geological Survey (U.S.). The deepest well ever drilled for any reason, the Kola Superdeep Borehole in Russia, only went down 40,230 feet. Their chief innovation was that, instead of turning the drill bit by rotating the stem, in the Kola well the bit alone was turned by the flow of drilling mud. In spite of Arrhenius misunderstanding of Fourier, the Concise Oxford English Dictionary (11th Edition) reflects his initial opening description of the Greenhouse Effect: Is hitting molten sulfur common? The world's most viewed site on global warming and climate change, This eye-catching blog post was published in 2017 by Fuel Fighter. The maximum bottom hole temperature (213F) was encountered in the Mississippi Canyon (MC) 777 TF001 well, drilled by BP. Probably not. On Russia's Kola Peninsula, near the Norwegian border at about the same latitude as Prudhoe Bay, the Soviets have been drilling a well since 1970. 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.
