Downhole Bazooka

WWII anti-tank weapon helped improve technologies for perforating well casings.

Swiss inventor Henry Mohaupt used his experience from creating a World War II anti-tank weapon to develop a new technology for improving production of oil and natural gas wells. He used conically hollowed-out explosive charges to focus each detonation’s energy.

In 1951, Henry Mohaupt applied for a U.S. patent for his “Shaped Charge Assembly and Gun,” based on anti-tank technology he had patented a decade earlier – a conically hollowed out explosive fired from bazookas.

First Dry Hole

Unsuccessful 1859 Pennsylvania oil well achieved many U.S. petroleum industry “firsts.”

 

Oil and natural gas exploration and production technologies began with the earliest wells of the mid-19th century in northwestern Pennsylvania. Just four days after America’s first commercial oil well of August 27, 1859, a second attempt nearby resulted in the first “dry hole” for the new U.S. petroleum industry.

Edwin L. Drake drilled the first U.S. oil well specifically seeking oil at a creek near Titusville, Pennsylvania. His historic feat included inventing of a method of driving a pipe down to protect the integrity of the well bore. The former railroad conductor borrowed a kitchen water pump to produce the first barrel of oil.

In addition to finding the more visible Pennsylvania historical marker on U.S. 62 near Tidioute, Pennsylvania, dedicated oil historians can discover the well site of America’s first dry hole — and find a 1959 oil centennial monument to John L. Grandin’s effort. Photos from a 1996 field trip, courtesy William R. Brice.

Although Drake’s headline-making discovery at Oil Creek launched an industry, an August 31 well would achieve far lesser known milestones. It was on that day that 22-year-old John Livingston Grandin began drilling America’s second well to be drilled for petroleum.

Firsts of the Second U.S. Well

Despite not finding the oil-producing formation (later called the Vanango Sands), the Grandin well produced technology firsts for the young exploration and production industry, including:

♦ First dry hole,
♦ first well in which tools stuck,
♦ first well “shot” with an explosive charge. (more…)

Rocky Beginnings of Petroleum Geology

Petroleum pioneers who took earth science to a deeper level.

 

When oil burst onto western Pennsylvania’s marketplace as a major commercial opportunity following an 1859 well, drilled by a former railroad conductor, the art and science of petroleum geology was born.

The coal-mining industry had long provided employment for geologists and the oil boom presented a new kind of mineral wealth for America and a new challenge for geologists. But Pennsylvania’s first oilmen soon found that hiring geologists didn’t significantly improve their chances of success in an already risky business.

Henry D. Rogers, (1808 – 1866) was one of the first professional U.S. geologists.

Decades before the Civil War, the pursuit and mining of coal prompted many geological surveys, studies, and assessments of potential mineral resources. Railroads stretching westward needed good quality coal supplies and routes always considered the availability of nearby sources.

Searching for high-quality bituminous coal, geologists had often reported oil seeps and the associated landforms, but mostly as a curiosity and in relation to their proximity to coal beds. In Kentucky, Ohio, and the western part of what is now West Virginia, the salt business also gave geologists important insights into formations called “structural traps.”

Drilling commercial brine wells and salt manufacturing was a lucrative industry. Geologists’ surveys found that strata of sedimentary rock fractured, faulted, and folded, sometimes producing salt domes and brine deposits.

Geologists also noted that oil and natural gas was occasionally trapped in porous deposits sandwiched between impermeable rock layers. Such contamination fouled commercial brine wells and was an unwelcome intrusion, but cottage industry entrepreneurs skimmed it off and sold it for patent medicine, lubrication, and other novel purposes.

Illustration of oil and gas traps in petroleum geology.

In Kentucky, Ohio and West Virginia, geologists studied landforms associated with salt brine and coal “structural traps.” These anticlinal traps held oil and natural gas because the earth had been bent, deformed or fractured. Unsuccessfully applying structural trap theories to Pennsylvania’s differing geology undermined early petroleum geologists’ credibility.

A pioneering Ohio physician and natural scientist named Samuel Hildreth examined and recorded details of the salt business in southeastern Ohio, noting structural traps as a geologic feature associated with brine, coal, and oil. In 1836, he published his extensive “Observations on the Bituminous Coal Deposit for the Valley of the Ohio, and the Accompanying Rock Strata.” It was America’s first petroleum geology primer.

Hildreth was a strong advocate for Ohio’s first geological survey and later served as the state geologist. His observations of the structural trapping of petroleum were later affirmed by Pennsylvania’s state geologist, Henry D. Rogers, who erroneously declared that Pennsylvania’s oilfields were likewise based on structural trapping of petroleum in anticline formations.

Pennsylvania’s oilfields were in fact found predominantly in another kind of formation altogether, the “sandstone stratigraphic trap,” but Rogers’ prestigious endorsement, circulated widely in an 1863 Harper’s Magazine article, convinced geologists to the contrary. The frenzied search for oil prompted the first petroleum geologists to impose Hildreth and Rogers’ structural trapping theory on Pennsylvania’s differing geology. It didn’t work and their failures in Pennsylvania hindered the acceptance of petroleum geologists for decades.

Although structural trapping remains a dominant characteristic for many of America’s most prolific oil and natural gas fields, ironically it wasn’t so in Pennsylvania’s Oil Creek region, where the petroleum industry was born. As noted by author and geologist Ray Sorenson, “theories of trapping did not work in the absence of anticlines.”

Pennsylvania sedimentary geologic formation known as a “stratigraphic trap.”

The dominant oil bearing feature in Pennsylvania’s oil region is a sedimentary geologic formation known as a “stratigraphic trap” and differs significantly from a structural trap. It is formed in place by erosion, usually in porous sandstone enclosed in shale. The impermeable shale keeps the oil and gas from escaping.

It took until the turn of the century before successful geologically driven discoveries in the Mid-Continent and Gulf regions encouraged exploration companies to use petroleum geologists.

Although the science of geology had revealed the 34-square-mile El Dorado oilfield in central Kansas in 1915, many companies still had little confidence in geologists.

James C. Donnell, president of the Ohio Oil Company (later Marathon Oil) proclaimed, “The day The Ohio has to rely on geologists, I’ll get into another line of work.” But after the company’s first geologist, C.J. “Charlie” Hares found 19 oil and natural gas fields, Donnell changed his mind and declared Hares to be “the greatest geologist in the world.”

AAPG inspires professional conduct amongst its more than 30,000 members.

Increasing understanding and acceptance of petroleum geology as a valued tool in exploration led to the 1917 formation of the Southwestern Association of Petroleum Geologists, precursor to today’s American Association of Petroleum Geologists. Since then, AAPG has fostered scientific research, advanced the science of geology, and promoted new technologies.  

Father of Petroleum Engineering

John Franklin Carll, a geologist born in Bushwick, New York, on May 7, 1828, could be considered the world’s first petroleum engineer. He developed many of the exploration and production industry’s geological methods — and helped pioneering oil driller Lyne Taliaferro Barret drill the first Texas oil well.

In 1875, Carll published strip logs from nine Pennsylvania wells, and he used them for correlation purposes in much the same manner as they are employed today,” noted the Society of Petroleum Engineers (SPE). “His work also confirmed the theory that oil sands lie in lens-shaped masses, not in continuous belts, and that oil does not occur in underground pools or lakes, but in pores of sandstone.” 

“More than a century ago, he expressed the principles of expressed the principles of petroleum engineering and geology that established much of the framework for the development of petroleum engineering technology,” proclaimed SPE, which established the John Franklin Carll Award in 1958.

The earth sciences of petroleum geology and engineering have come a long way since pioneering steps and stumbles in the Ohio River Valley and Pennsylvania’s early oilfields. Geologists today grapple with enormous amounts of data and technological innovations in pursuit of petroleum.

Making Hole – Drilling Technology

Petroleum industry answers to necessity and opportunity for finding oil and natural gas at greater depths.

 

“A good cable-tool man is just about the most highly skilled worker you’ll find,” one historian noted. “Besides having a feel for the job, knowing what’s going on thousands of feet under the ground just from the movement of the cable, he’s got to be something of a carpenter, a steam-fitter, an electrician, and a damned good mechanic.” – A 1939 interview in “Voices from the Oil Fields” by Paul Lambert and Kenny Franks.

Petroleum exploration technologies have evolved from ancient “spring poles,” to steam-powered percussion cable-tools, to modern rotary rigs with diamond bits that can drill miles into the earth.

“A cable tool driller knows more knots and splices than any six sailors you can find,” noted historians Lambert and Franks in their 1984 book, a collection of 1930s Federal Writers Project interviews  about oilfield life. The stories — featuring cable-tool rigs with giant “bull wheels” spinning off manila rope — reported firsthand accounts of the “grueling toil, primitive living and working conditions, and ever-present danger in a time when life was cheap and oil was gold.”

Drilling or “making hole” began long before crude oil or natural gas were anything more than flammable curiosities found seeping from the ground. For centuries, digging by hand or shovel was the best technologies that existed to pry into the earth’s secrets. Oil seeps provided a balm for injuries. Natural gas seeps – when ignited – created folklore and places called “burning springs.” (more…)

Exploring Seismic Waves

Oklahoma scientists first used reflection and refraction technologies in the 1920s.

 

Exploring seismic waves is all about a vital earth science technology — reflection seismography — which first revolutionized petroleum exploration in the 1920s. Seismic waves have led to oilfield discoveries worldwide and billions of barrels of oil. 

Seismic technologies evolved from efforts to locate enemy artillery during World War I.

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…)
