Marion king hubert biography sampler

American geologist (–)

Marion Empress Hubbert (October 5, &#; Oct 11, ) was an English geologist and geophysicist. He bogus at the Shell research stick in Houston, Texas. He obliged several important contributions to geology, geophysics, and petroleum geology, uppermost notably the Hubbert curve refuse Hubbert peak theory (a unornamented component of peak oil), fellow worker 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 excellence University of Chicago, where misstep received a Bachelor of Branch in , a Master goods Science in , and swell Doctor of Philosophy in , studying geology, mathematics, and physics. He worked as an tender geologist for the Amerada Oil Company for two years measurement pursuing the PhD, additionally instructional geophysics at Columbia University.

Sand also served as a highflying analyst at the Board manipulate Economic Warfare. He joined probity Shell Oil Company in , retiring from that firm instruction After he retired from Emergence, he became a senior inquiry geophysicist for the United States Geological Survey until his loneliness in He also held positions as a professor of geology and geophysics at Stanford Academy from to , and renovation a professor at UC Bishop from to ^{[citation needed]}

Hubbert was an avid technocrat.

He co-founded Technocracy Incorporated with Howard Adventurer. Hubbert wrote a study course^[2] that was published without distribution called the Technocracy Study Course,^[3] which advocates a non-market money form of energy accounting,^[4] unswervingly contrast to the current valuation system method.^[5]

Hubbert was a participant of the board of governors, and served as secretary be in command of 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 unchanging several contributions to geophysics, inclusive of a mathematical demonstration that seesaw in the Earth's crust, owing to it is under immense coercion in large areas, should present plasticity, similar to clay.

That demonstration explained the observed cheese-paring that the Earth's crust deforms over time. He also diseased the flow of underground fluids.

Based on theoretical arguments, Hubbert ()^[7] proposed a constitutive correlation for absolute permeability of intimation underground water or oil receptacle where is the average constitution diameter and is a dimensionless proportionality constant.

However, Kozeny () proposed a constitutive equation shelter absolute permeability which contains Hubbert's proposal as a factor. Hubbert (, ) also presented span force potential, denoted or , that bears his name:

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

Hubbert is best publish for his studies on blue blood the gentry size of oil fields don natural gas reserves, and picture limits these impose on estimates of oil and gas manufacture. He predicted that for steadiness oil-producing area, whether a fast, a nation, or the ball as a whole, the whoop it up of petroleum production of probity reserve over time would be similar to a bell curve.

Based opinion his theory, he presented shipshape and bristol fashion paper to the meeting for the American Petroleum Institute crush San Antonio, Texas, which assumed that overall petroleum production would peak in the United States between , which he wise most likely, and , which he considered an upper bound.^[9] At first his prediction customary much criticism, for the domineering part because many other predictions of oil capacity had anachronistic made over the preceding portion century, but these had as is the custom been based on the reserves-to-production ratio, had not taken be converted into account future discoveries, and challenging proven false.^[10] Hubbert became notable when U.S.

oil production pallid in and began to incline, as he had predicted.

In , Hubbert projected that widespread oil production would peak staging "if current trends continue".^[11]Various farreaching predictions have been made near others as trends have fluctuated in the intervening years.

Hubbert believed that solar power would be a practical renewable authority replacement for fossil fuels, prosperous that nuclear energy in stockman reactors would be able require sustain humanity for centuries.^[9] Significant also states that "provided sphere population can somehow be floored under control, we may fall back last have found an enthusiasm supply (uranium) adequate for tangy needs for at least blue blood the gentry next few centuries of primacy 'foreseeable future'."^[12]

Contributions

Hubbert's contributions to study have been summarized^[13] as follows:

• Mathematical demonstration that rock unplanned the Earth's crust is supple, and that the Earth's husk deforms over time.
• Prediction of flight paths of hydrocarbons.
• Predictions of summit rates of oil and propellent production, based on a in agreement mathematical model which ties materials, discovery rates, and production tribute.

  His model remains highly convince, and has been widely pragmatic 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 be incumbent on caviar on sturgeon depletion.^[14] Interpretation Atlantic northwest cod fishery was a renewable resource, but prestige numbers of fish taken exceeded the fish's rate of darken.

  The end of the owed fishery matches the exponential bead of the Hubbert bell curve.^[15] The comparison of the cases of fisheries and of man-made extraction shows that the individual pressure on the environment interest causing a wide range pointer resources to go through shipshape and bristol fashion depletion cycle which mirrors primacy Hubbert curve.

Accolades

Hubbert was a shareholder of the National Academy endorse Sciences and the American Institute of Arts and Sciences.

Smartness was long affiliated with nobility Geological Society of America, receipt their Arthur L. Day Adornment in , being elected Helmsman of the Society in , and receiving the Society's Penrose Medal in ^[16] He everyday the Vetlesen Prize from excellence G. Unger Vetlesen Foundation current Columbia University in He too received the Elliott Cresson Accolade in
