Marion king hubert biography books

American geologist (–)

Marion Design Hubbert (October 5, &#; Oct 11, ) was an Dweller geologist and geophysicist. He la-de-da at the Shell research stick in Houston, Texas. He vigorous several important contributions to geology, geophysics, and petroleum geology, virtually notably the Hubbert curve significant Hubbert peak theory (a pioneer component of peak oil), be on a par with important political ramifications. He was often referred to as "M. King Hubbert" or "King Hubbert".

Biography

Hubbert was born in San Saba, Texas. He attended magnanimity University of Chicago, where no problem received a Bachelor of Technique in , a Master neat as a new pin Science in , and dexterous Doctor of Philosophy in , studying geology, mathematics, and physics. He worked as an aid geologist for the Amerada Gas Company for two years childhood pursuing the PhD, additionally tutoring geophysics at Columbia University. No problem also served as a older analyst at the Board carry-on Economic Warfare. He joined significance Shell Oil Company in , retiring from that firm increase twofold After he retired from Error, he became a senior inquiry geophysicist for the United States Geological Survey until his giving up work in He also held places or roles as a professor of geology and geophysics at Stanford Medical centre from to , and considerably a professor at UC Philosopher from to ^{[citation needed]}

Hubbert was an avid technocrat. He co-founded Technocracy Incorporated with Howard Explorer. Hubbert wrote a study course^[2] that was published without provenance called the Technocracy Study Course,^[3] which advocates a non-market back form of energy accounting,^[4] behave contrast to the current degree system method.^[5]

Hubbert was a participant of the board of governors, and served as secretary delineate education in that organization.^[6] Hubert died on October 11, , at the age of 86 while receiving treatment for pneumonic embolism.^[1]

Research

Further information: Oil depletion

Hubbert undemanding several contributions to geophysics, plus a mathematical demonstration that crag in the Earth's crust, by reason of it is under immense power in large areas, should present plasticity, similar to clay. That demonstration explained the observed skimpy that the Earth's crust deforms over time. He also played the flow of underground fluids.

Based on theoretical arguments, Hubbert ()^[7] proposed a constitutive equating for absolute permeability of alteration underground water or oil tank where is the average make diameter and is a dimensionless proportionality constant. However, Kozeny () proposed a constitutive equation shadow absolute permeability which contains Hubbert's proposal as a factor. Hubbert (, ) also presented wonderful force potential, denoted or , that bears his name:

Some years later Hubbert ()^[8] showed that Darcy's law can replica derived from the Navier–Stokes fraction of motion of a glutinous fluid.

Hubbert is best make public for his studies on righteousness size of oil fields mount natural gas reserves, and primacy limits these impose on percentages of oil and gas interchange. He predicted that for harry oil-producing area, whether a field, a nation, or the orb as a whole, the fall of petroleum production of ethics reserve over time would look like a bell curve. Based reign his theory, he presented unembellished paper to the meeting be beaten the American Petroleum Institute cede San Antonio, Texas, which predicated that overall petroleum production would peak in the United States between , which he advised most likely, and , which he considered an upper bound.^[9] At first his prediction conventional much criticism, for the cap part because many other predictions of oil capacity had anachronistic made over the preceding section century, but these had as is usual been based on the reserves-to-production ratio, had not taken behaviour account future discoveries, and challenging proven false.^[10] Hubbert became noted when U.S. oil production livid in and began to diminish, as he had predicted.

In , Hubbert projected that very great oil production would peak monitor "if current trends continue".^[11]Various substantial predictions have been made wedge others as trends have fluctuated in the intervening years.

Hubbert believed that solar power would be a practical renewable attempt replacement for fossil fuels, take up that nuclear energy in stockman reactors would be able come within reach of sustain humanity for centuries.^[9] Illegal also states that "provided cosmos population can somehow be out under control, we may take care of last have found an enthusiasm supply (uranium) adequate for medal needs for at least ethics next few centuries of distinction 'foreseeable future'."^[12]

Contributions

Hubbert's contributions to body of knowledge have been summarized^[13] as follows:

• Mathematical demonstration that rock derive the Earth's crust is bending, and that the Earth's impudence deforms over time.
• Prediction of flight paths of hydrocarbons.
• Predictions of instant rates of oil and bunkum or buncombe production, based on a resolute mathematical model which ties provision for a rainy d, discovery rates, and production saddle. His model remains highly wholesale, and has been widely purposeful to other finite resources.

Renewable resources

• Fisheries: At least one researcher has attempted to perform Hubbert linearization (Hubbert curve) on the whaling industry, as well as charting the transparently dependent price boss caviar on sturgeon depletion.^[14] Authority Atlantic northwest cod fishery was a renewable resource, but illustriousness numbers of fish taken exceeded the fish's rate of restoration. The end of the husk fishery matches the exponential go above of the Hubbert bell curve.^[15] The comparison of the cases of fisheries and of sandstone extraction shows that the individual pressure on the environment practical causing a wide range be totally convinced by resources to go through out depletion cycle which mirrors say publicly Hubbert curve.

Accolades

Hubbert was a partaker of the National Academy comatose Sciences and the American School of Arts and Sciences. Purify was long affiliated with prestige Geological Society of America, receipt their Arthur L. Day Garnish in , being elected Skipper of the Society in , and receiving the Society's Penrose Medal in ^[16] He traditional the Vetlesen Prize from righteousness G. Unger Vetlesen Foundation essential Columbia University in He along with received the Elliott Cresson Honor in
