Ending Oil Gushers – BOP

It took the ingenuity of a skilled machinist and a Texas wildcatter to invent a device to stop gushers.



Petroleum drilling and production technologies, among the most advanced of any industry, evolved as exploratory wells drilled deeper into highly pressurized geologic formations. One idea began with a sketch on the sawdust floor of a Texas machine shop.

In January 1922, James Abercrombie and Harry Cameron sought their first U.S. patent for the hydraulic ram-type blowout preventer. The invention would become a vital technology for ending dangerous oil and natural gushers. 

“The object of our invention is to provide a device designed to be secured to the top of the casing while the drilling is being done and which will be adapted to be closed tightly about the drill stem when necessary,” they noted in their patent application, which was finalized and approved four years later. The design revolutionized the petroleum industry. (more…)

Sweeny’s 1866 Rotary Rig

An innovative patent for “making holes in hard rock.”


An “Improvement in Rock Drills” patent issued after the Civil War included the basic elements of the modern petroleum industry’s rotary rig.  On January 2, 1866, Peter Sweeney of New York City was granted U.S. patent No. 51,902 for a drilling system with many innovative technologies. 

Sweeny’s 1866 rotary rig design, which improved upon an 1844 British patent by Robert Beart, applied rotary drilling’s “peculiar construction particularly adapted for boring deep wells.” More efficient than cable-tool percussion bits, the patent provided for a roller bit with replaceable cutting wheels such “that by giving the head a rapid rotary motion the wheels cut into the ground or rock and a clean hole is produced.”

Peter Sweeney’s innovative 1866 “Stone Drill” patent included a roller bit using “rapid rotary motion” similar to modern rotary drilling technologies.

Sweeney’s design utilized a roller bit with replaceable cutting wheels such “that by giving the head a rapid rotary motion the wheels cut into the ground or rock and a clean hole is produced.” In another innovation, the “drill-rod” was hollow and connected with a hose through which “a current of steam or water can be introduced in such a manner that the discharge of the dirt and dust from the bottom of the hole is facilitated.”

Better than commonly used steam-powered cable-tools, which used heavy rope to lift and drop iron chisel-like bits, Sweeney claimed his drilling apparatus could be used with great advantage for “making holes in hard rock in a horizontal, oblique, or vertical direction.”

Drilling operations could be continued without interruption, Sweeny explained in his patent application, “with the exception of the time required for adding new sections to the drill rod as the depth of the hole increases. The dirt is discharged during the operation of boring and a clean hole is obtained into which the tubing can be introduced without difficulty.”

Foreseeing the offshore exploration industry, Sweeney’s patent concluded with a note that “the apparatus can also be used with advantage for submarine operations.”

With the American oil industry booming, drilling contractors improved upon Sweeney’s idea. A new device was fitted to the rotary table that clamped around the drill pipe and turned. As this “kelly bushing” rotated, the pipe rotated – and with it the bit down hole. The torque of the rotary table was transmitted to the drill stem.

Thirty-five years after Sweeney’s patent, rotary drilling revolutionized the petroleum industry after a 1901 oil discovery by Capt. Anthony Lucas launched a drilling boom at Spindletop Hill near Beaumont, Texas. Learn more at Making Hole – Drilling Technology.

Fishing in Petroleum Wells

From the petroleum industry’s earliest days, when tools stuck downhole, drilling stopped. 


The challenge of retrieving broken (and often expensive) equipment obstructing a well — “fishing” — began tormenting oil and natural gas exploration companies since the first tool stuck irretrievably at 134 feet deep and ruined a Pennsylvania well.

Just four days after the August 27, 1859, first U.S. oil discovery by Edwin L. Drake in Pennsylvania’s “valley that changed the world,” a far less known driller began America’s second well to be drilled for petroleum. John Livingston Grandin drilled his well nearby using a simple spring pole — but soon wedged his iron chisel downhole. The 22-year-old Grandin improvised his own well fishing tools, but not only lost his drill bit (an industry first), he ended up with the America’s first dry hole.  

Searching for petroleum was less an earth science and more an art in the oil industry’s earliest days. Geologist knew far more about finding coal seams than characteristics of oil-bearing formations. Even as drilling technologies evolved from spring poles and cable tools to modern rotary rigs, downhole problems remained — especially as wells reached new depths (learn more about development of rotary rigs in Making Hole – Drilling Technology).

A 19th century cable-tool rig, like its ancient predecessor the spring pole, utilized percussion drilling — the repeated lifting and dropping of a heavy chisel using hemp ropes. Drilling time and depth improved with the addition of steam power and tall, wooden derricks. As depths increased, frequent stops were needed to bail out water and cuttings — and sharpen the wedged drill bit made of iron. 

Expensive drilling tools also would get jammed deep in the borehole. Perhaps the rig’s manila rope or wire line would break. A pipe connection might bend or break. The increasingly heavy downhole tool assemblies could no longer be lifted and dropped. 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. Sometimes a wood, wax and nails “impression block” was first lowered to get an idea of what lay downhole.

Cable-Tool Fishing Equipment 

In percussion drilling, the heavy cable-tool assembly cwould get jammed in the borehole and could no longer be repeatedly lifted and dropped. In the foreground of the photograph below, the large wheel at right (with small, square hub) received the uppermost part of a fishing pole. A rope was wound around this wheel’s rim and led to the “bull wheel” shaft.

Circa 1880s wooden cable-tool derrick, bull wheel and workers.

The term fishing came from early percussion drilling using cable-tools. When the derrick’s manila rope or wire line rope broke, a crewman lowered a hook and attempted to pull out the well’s heavy iron bit. Photo courtesy Library of Congress.

Among the fishing tools at the man’s feet are 3.5-inch iron poles, each 20 feet in length and weighing 500 pounds. To fish for stuck tools, these were lowered in well, armed at their end with a “die” with a left-hand thread cut in it. This die fit over the end of the stuck tool, tapered inward slightly, and when turned to the left, cut a thread on the cable tool.

The bull wheel, driven by the well’s steam-powered drilling engine, exerted a tremendous strain on the assembled poles. Since that strain was always to the left, the die gradually cut a thread in the stuck cable tool. One of the cable tool sections would eventually yield, unscrew, and be removed. The operation repeated until the lowest piece was reached. A “spud” was then employed.

Hooks, Spears, Knives and Whipstocks

“Well fishing tools are constantly being improved and new ones introduced,” explained David T. Day in his A Handbook of the Petroleum Industry in 1922. Describing cable tool operations, he explained that the basic principle of well fishing tools often involved milled wedges — on a spear or in a cylinder — for recovering lost tubing or casing.

As drillers gained experience with deeper wells, patent applications included hundreds of designs for catching some tool or part that broken or lost in the borehole. Many of these “fishing tools” could be created on site since most cable-tool rigs already had a forge for sharpening bits on the derrick floor. Cable-tool rigs would drill at night too, thanks to two-wicked “yellow dog” lanterns.

Day noted that the simpler types of fishing tools comprised “horn sockets, corrugated friction sockets, rope grabs, rope spears, bit hooks, spuds, whipstocks, fluted wedges, rasps, bell sockets, rope knives, boot jacks, casing knives and die nipples.”

Basic fishing tools include the spear and socket, each with milled edges. Using nails and wax, an impression block helps determine what is stuck downhole. Image from A Handbook of the Petroleum Industry, 1922.

These and other devices, when used with an auger stem in various combinations called jars, can secure a powerful upward stroke or “jar” and thus dislodge and recover the tool being sought, Day explained in his 1922 book. “The jars, essentially and universally used in fishing with cable tools, consist off two heavy forged-steel links, interlocking as the links of a cable chain, but fitting together more snugly.”

“Many lost tools that cannot be recovered are drilled up or ‘side-tracked” (driven into or against the wall) and passed in drilling,” Day explained. Much depended upon “the skill and patience of the driller.” Once all well fishing tools failed, a final resort was a whipstock, which allowed the bit to angle off and actually bypass the fish but leaves the operator with a deviated hole. This was sometimes unpopular where wells were closely spaced.

By the early 1900s, rotary drilling introduced the hollow drill stem that enabled broken rock debris to be washed out of the borehole. It led to far deeper wells.

By the early 1900s, rotary drilling introduced the hollow drill stem that enabled broken rock debris to be washed out of the borehole. It led to far deeper wells.

As drilling with rotary rigs became more common in the early 1900s, fishing methods adapted. “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.”

Most rotary fishing jobs were caused by “twist offs” (broken drill pipe), although the bit, drill coupling or tool joints may break or unscrew. As in cable-tool fishing, an impression block often was needed to determine the proper fishing tool. But even back then — and especially now with wells miles deep and often turned horizontally — when a downhole problem occurred, the well could be lost for good.

Historic Bertha Rogers No. 1

The Anadarko Basin extends across western Oklahoma into the Texas Panhandle and into southwestern Kansas and southeastern Colorado. It includes the Hugoton-Panhandle field, the Union City field and the Elk City field and is among the most prolific natural gas producing areas in North America.

In 1980, the Oklahoma Historical Society and Oklahoma Petroleum Council dedicated a granite monument at Third and Pioneer streets in Elk City, Oklahoma. The Washita County marker notes:

The Deep Anadarko Basin of Western Oklahoma is one of the most prolific gas provinces of North America. Wells drilled here have been among the world’s deepest.

Ad link to join AOGHS in 2020

The Bertha Rogers No. 1 in Washita County, drilled in 1971 to 31,441 feet, was then the world’s deepest well. In 1979 the No. 1 Sanders well near Sayre became Oklahoma’s deepest gas producer at 24,996 feet.

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.

The shallow horizons of Greater Anadarko account for much of this nation’s proved gas reserves. Deeper sediments below 15,000 feet remain virtually unexplored. Renewed assessment of some 22,000 cubic miles of deep sediments may carry over into the 21st Century.

For 20th Century’s final quarter the Basin remains the frontier of deep drilling technology centered on Elk City, “Deep Gas Capital of the World”. As gas prices equate more closely to value, the nation’s needs may be met increasingly from this massive sedimentary basin, a focal point in drilling innovation and geological interpretation.

In re-energizing America, Anadarko will not yield its gas easily or briefly. Promised rewards lying beyond the threshold of drilling techniques demand massive investment. In challenging the inventive enterprise of America’s energy industry, this Basin will remain the heartland of technology in penetrating the earth’s crust.


A 1974 souvenir of the Bertha Roger No. 1 well, which sought natural gas almost six miles deep in Oklahoma’s Anadarko Basin.

Until the 1960s, few companies could risk millions of dollars and push rotary rig drilling technology to reach beyond the 13,000-foot level in what geologists called “the deep gas play.”

The great expense and technological expertise necessary to complete ultra-deep natural gas wells at these depths made the Anadarko Basin “the domain of the major petroleum corporations,” explained Bobby Weaver, oil historian and frequent article contributor to the Oklahoma Historical Society.

GHK Company and partner Lone Star Producing Company believed ultra-deep wells in Oklahoma’s Anadarko Basin could produce massive amounts of natural gas. They began drilling wells more than three miles deep in the late 1960s. South of Burns Flat in Washita County, their Bertha Rogers No.1 would reach almost six miles deep in 1974 — after a deep fishing trip.

Deep Fishing in Oklahoma 

In March 1974 in far western Oklahoma, after 16-months of drilling and almost six miles deep, the Bertha Rogers No. 1 rotary rig drill stem sheared, leaving 4,111 feet of pipe and the drill bit stuck downhole. Spudded in November 1972 and averaging about 60 feet per day, the Bertha Rogers had been heading for the history books as the world’s deepest well at the time.

It was March 1974 and the enormous investment of Lone Star Producing Company of Dallas, and partner GHK Company of Oklahoma City, was about to be lost. Desperate GHK executives called a Houston fishing company. Millions of dollars hung in
the balance when Houston-based Wilson Downhole Service Company, Houston, was called and “fishing” expert Mack Ponder sent to the rescue.

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 Oklahoma’s Anadarko Basin, at a site about 12 miles west of Cordell.

Although the remarkable deep fishing achievement was celebrated, the Bertha Rogers No. 1 had to be completed at just 14,000 feet after striking molten sulfur at 31,441 feet. The equipment could not take the abuse at total depth. The well set a world record and remains one of the deepest ever drilled. In 1979, the No. 1 Sanders well near Sayre in Beckham County became Oklahoma’s deepest natural gas producer at 24,996 feet.

Oilfield Artillery fights Fires

“Small cannons throwing a three-inch solid shot are kept at various stations throughout the region…”


Early petroleum technologies included cannons for fighting oil-tank storage fires, especially in the great plains where lightning strikes often ignited derricks and tanks. Shooting cannon balls into the base of a burning tank allowed oil to drain into a holding pit until fire died.

“Oil Fires, like battles, are fought by artillery,” proclaimed a December 1884 article from the Massachusetts Institute of Technology. (more…)

Project Gasbuggy tests Nuclear “Fracking”

Government scientists blast deep natural gas wells trying to increase production.


Project Gasbuggy was the first in a series of Atomic Energy Commission downhole nuclear detonations to release natural gas trapped in shale. This was “fracking” late 1960s style.

In December 1967, government scientists – exploring the peacetime use of controlled atomic explosions – detonated Gasbuggy, a 29-kiloton nuclear device they had lowered into an experimental well in rural New Mexico. The Hiroshima bomb of 1945 was about 15 kilotons.

Scientists lowered a 13-foot by 18-inches diameter nuclear device into a New Mexico gas well. The experimental 29-kiloton Project Gasbuggy bomb was detonated at a depth of 4,240 feet. Los Alamos Lab photo.

Project Gasbuggy’s team included experts from the Atomic Energy Commission, the U.S. Bureau of Mines and El Paso Natural Gas Company. They sought a new, powerful method for fracturing petroleum-bearing formations. Near three low-production natural gas wells, the team drilled to a depth of 4,240 feet – and lowered a 13-foot-long by 18-inch-wide nuclear device into the borehole.

Plowshare Program: Peaceful use of Nukes

The 1967 experimental explosion in New Mexico was part of a wider set of experiments known as Plowshare, a program established by the Atomic Energy Commission in 1957 to explore the constructive use of nuclear explosive devices.

project gasbuggy geology diagram

The 1967 nuclear detonation produced 295 million cubic feet of natural gas – and Tritium radiation.

“The reasoning was that the relatively inexpensive energy available from nuclear explosions could prove useful for a wide variety of peaceful purposes,” noted a report later prepared for the U.S. Department of Energy. From 1961 to 1973, researchers carried out dozens of separate experiments under the Plowshare program – setting off 29 nuclear detonations.

Most of the experiments focused on creating craters and canals. Among other goals, it was hoped the Panama Canal could be inexpensively widened. “In the end, although less dramatic than nuclear excavation, the most promising use for nuclear explosions proved to be for stimulation of natural gas production,” explains the September 2011 government report.

Tests, mostly conducted in Nevada, also took place in the petroleum fields of New Mexico and Colorado. Project Gasbuggy was the first of three nuclear fracturing experiments that focused on stimulating natural gas production. Two later tests took place in Colorado.

Atomic Energy Commission scientists worked with experts from the Astral Oil Company of Houston, with engineering support from CER Geonuclear Corporation of Las Vegas. The experimental wells, which required custom drill bits to meet the hole diameter and narrow hole deviation requirements, were drilled by Denver-based Signal Drilling Company or its affiliate, Superior Drilling Company. Project Rulison was the second of the three nuclear gas well stimulation projects.

Gasbuggy: “Site of the first United States underground nuclear experiment for the stimulation of low-productivity gas reservoirs.”

In 1969, Project Rulison – at a site near Rulison, Colorado – detonated a 43-kiloton nuclear device almost 8,500 feet underground to produce commercially viable amounts of natural gas. A few years later, project Rio Blanco, northwest of Rifle, Colorado, was designed to increase natural gas production from low-permeability sandstone.

The May 1973 Rio Blanco test consisted of the nearly simultaneous detonation of three 33-kiloton devices in a single well, according to the Office of Environmental Management. The explosions occurred at depths of 5,838, 6,230, and 6,689 feet below ground level. It would prove to be the last experiment of the Plowshare program.

Although a 50-kiloton nuclear explosion to fracture deep oil shale deposits – Project Bronco – was proposed, it never took place. Growing knowledge (and concern) about radioactivity ended these tests for the peaceful use of nuclear explosions. The Plowshare program was canceled in 1975. In its September 2011 report on all the nuclear test projects, the U.S. Department of Energy concluded:

By 1974, approximately 82 million dollars had been invested in the nuclear gas stimulation technology program (i.e., nuclear tests Gasbuggy, Rulison, and Rio Blanco). It was estimated that even after 25 years of gas production of all the natural gas deemed recoverable, that only 15 to 40 percent of the investment could be recovered. At the same time, alternative, non-nuclear technologies were being developed, such as hydrofracturing. Consequently, under the pressure of economic and environmental concerns, the Plowshare Program was discontinued at the end of FY 1975.

Project Gasbuggy: Nuclear Fracking

“There was no mushroom cloud, but on December 10, 1967, a nuclear bomb exploded less than 60 miles from Farmington,” explained historian Wade Nelson in an article written three decades later, “Nuclear explosion shook Farmington.”

project gasbuggy government fracturing illustration

Government scientists believed a nuclear device would provide “a bigger bang for the buck than nitroglycerin” for fracturing dense shales and releasing natural gas. Los Alamos Lab photo.

The 4,042-foot-deep detonation created a molten glass-lined cavern about 160 feet in diameter and 333 feet tall. It collapsed within seconds. Subsequent measurements indicated fractures extended more than 200 feet in all directions — and significantly increased natural gas production.

A September 1967 Popular Mechanics article had described how nuclear explosives could improve previous fracturing technologies, including gunpowder, dynamite, TNT – and fractures “made by forcing down liquids at high pressure.” (Erle Halliburton had tested hydraulic fracturing in the late 1940s.)

An illustration from Popular Mechanics shows how a nuclear explosive would improve earlier technologies by creating bigger fractures and a “huge cavity that will serve as a reservoir for the natural gas.”

Scientists predicted that nuclear explosives would create more and bigger fractures “and hollow out a huge cavity that will serve as a reservoir for the natural gas” released from the fractures.

“Geologists had discovered years before that setting off explosives at the bottom of a well would shatter the surrounding rock and could stimulate the flow of oil and gas,” Nelson explained. “It was believed a nuclear device would simply provide a bigger bang for the buck than nitroglycerin, up to 3,500 quarts of which would be used in a single shot.”

The underground detonation was part of a bigger program begun in the late 1950s to explore peaceful uses of nuclear explosions.

“Today, all that remains at the site is a plaque warning against excavation and perhaps a trace of tritium in your milk,” Nelson added in his 1999 article. He quoted James Holcomb, the site foreman for El Paso Natural Gas, who saw a pair of white vans that delivered pieces of the disassembled nuclear bomb.

“They put the pieces inside this lead box, this big lead box…I (had) shot a lot of wells with nitroglycerin and I thought, ‘That’s not going to do anything,” reported Holcomb. A series of three production tests, each lasting 30 days, was completed during the first half of 1969. Government records indicated the Gasbuggy well produced 295 million cubic feet of natural gas.

“Nuclear Energy: Good Start for Gasbuggy,” proclaimed the December 22, 1967, TIME magazine. The Department of Energy, which had hoped for much higher production, determined that Tritium radiation contaminated the gas. It  flared – burned off – the gas during production tests that lasted until 1973. Tritium is a naturally occurring radioactive form of hydrogen. A 2012 the Nuclear Regulatory Commission report noted, “Tritium emits a weak form of radiation, a low-energy beta particle similar to an electron. The tritium radiation does not travel very far in air and cannot penetrate the skin.”

project gasbuggy marker

A plaque marks the site of Project Gasbuggy in the Carson National Forest, 90 miles northwest of Santa Fe, New Mexico.

According to Nelson, radioactive contamination from the flaring “was miniscule compared to the fallout produced by atmospheric weapons tests in the early 1960s.” From the well site, Holcomb called the test a success. “The well produced more gas in the year after the shot than it had in all of the seven years prior,” he said.

Parker Drilling Rig No. 114

In 1969, Parker Drilling Company signed a contract with the U.S. Atomic Energy Commission to drill a series of holes up to 120 inches in diameter and 6,500 feet in depth in Alaska and Nevada for additional nuclear bomb tests. Parker Drilling’s Rig No. 114 was one of three special rigs built to drill the wells.

Parker Drilling Rig No. 114 – among those used to drill wells for nuclear detonations, was later modified to drill conventual wells. Since 1991 the 17-story rig has welcomed visitors to Elk City, Oklahoma, and the now shuttered Anadarko Museum of Natural History. Photo by Bruce Wells.

Founded in Tulsa in 1934 by Gifford C. Parker, by the 1960s Parker Drilling had set numerous world records for deep and extended-reach drilling. According to the Baker Library at the Harvard Business School, the company “created its own niche by developing new deep-drilling technology that has since become the industry standard.”

Following completion of the nuclear-test wells, Parker Drilling modified Rig No. 114 and its two sister rigs to drill conventual wells at record-breaking depths. After retiring Rig No. 114 from service, Parker Drilling loaned the giant to Elk City, Oklahoma, as an energy education exhibit next to the Anadarko Museum of Natural History. Since 1991 the has welcomed visitors to traveling on Route 66 or I-40 and the now closed oil museum. Learn more about deep drilling in Anadarko Basin in Depth.
