North Sea Oil Development

For Brent Spar ep[isode see Environment

6 July 1988. 173 men died in an explosion on the Piper Alpha oilrig in the North Sea. Many more were injured as a series of explosions wrecked the rig whilst they slept. The 12-year-old rig was 120 miles off the Aberdeen coast. Flames shot 400 feet into the air and only 62 survived, many by jumping over 100 feet into the sea. The heat could be felt one mile away, and hampered rescue efforts. 165 oil workers and 2 rescue workers were killed.

1938, The first oil was found in Saudi Arabia, in commercial quaitities, a mile underground at Dhahran.

23 February 1938, Oil was discovered in Kuwait. This was the large Burgan oilfield. However exploitation was delayed until after World War Two. Then, oil rapidly displaced pearling and fishing as Kuwait�s main source of income.

1937, Shell-BP began prospecting for oil inNigeria. Oil was discovered during World War Two, and commercial exploitation began in 1946.

14 January 1935, The Iraq � Mediterranean (Kirkuk to Haifa)oil pipeline was inaugurated.

14 July 1934, The oil pipeline from Mosul, Iraq, to Tripoli, Lebanon, opened.

1931, First major oilfield found in Bahrain. Oil extraction began in 1932.

1922, Exploration for oil began in Saudi Arabia.

15 October 1918, Britain�s first oil well was sunk, at Hardstoft in Derbyshire.

18 June 1915, Red Adair, specialist oil well firefighter, was born.

1913, Global crude oil production reached 407.5 million barrels, up from 5.7 million barrels in 1870. The USA now accounted for two thirds of this production, with California producing around 40% of the US total.

26 May 1908. Significant oil fields were found in Persia (Iran), the first oil strike in the Middle East.

Texas oilfields

11 March 1901, The tanker ship Atlas departed from Port Arthur, Texas, with 3,000 barrels of crude oil from the Spindletop oil fields, bound for the Standard Oil refineries in Philadelphia, marking the first shipments of Texas oil.

10 January 1901, Major oil discovery in Texas, USA. The salt dome of Spindletop had been suspected of containing oil since 1865; this day oil was struck; a gush of oil 6 inches wide rose over 200 feet, and was visible for over 10 miles. The population of nearby Beaumont rapidly rose from 10,000 to over 50,000, as oil production at Spindletop reached 100,000 barrels per day. Oil production in the area lasted until 1950.

1894, Oil was discovered in Texas, at Corsicana.as a well being drilled for water suddenly produced oil.

 

Pennsylvania oilfields

1869, Pennsylvania oil wells were now producing 4.8 million barrels per annum of crude oil.

27 August 1859. The world�s first oil well was drilled at Titusville, Pennsylvania, by Edwin Drake of Seneca Oil. Oil had been known in this area for 300 years. It used to seep from the ground and was used for curing many ailments from blindness to rheumatism, colds, coughs, sprains, and baldness. It was also skimmed from creeks and used for lighting, although it gave off a foul smell when burned. Chemists turned the oil into a better lighting fuel. Drake drilled down 69 feet and got a steady flow of 25 barrels a day from his well. By the end of the year the well once called �Drake�s Folly� had produced 2,000 barrels, and other prospectors joined in the search for more oil.

 

1854, The first fractional distillation of crude oil was performed, by Yale chemistry professor Benjamin Silliman Junior, aged 38. He had been asked by George Henry Bissell, aged 33, to analyse a sample of Pennsylvania �rock oil�, which burnt better than coal oil obtained from asphalt.

29 March 1819, Edward Laurentine Drake was born in Greenville, New York, USA. On 28 August 1859 he drilled the world�s first oil well.

For UK Miner�s Strikes see Great Britain

 

16 December 2015, The UK�s last deep coal mine, Kellingley Colliery, near Wakefield, Yorkshire, closed. It once employed 3,000 workers.

1995, British Coal was privatised.

13 October 1992. British Coal announced 31 pit closures and the loss of 31,000 jobs. This would leave just 19 pits in operation.

20 December 1990. The last coal mine in the Rhondda closed. Once 40,000 men worked at 56 pits here, and over 100 died in the mines. This day Maerdy Colliery closed, 300 were made redundant. Only 17 miners stayed in the industry, moving to other pits.

30 December 1986, The use of canaries in UK coal mines was discontinued.

31 March 1985, In Britain, the National Coal Board announced a record loss of �2,225 million.

13 March 1974, Britain�s newly-elected Labour Government wrote off the National Coal Board�s �105 million debt.

1966, The Lancashire coalfield now had eleven collieries, down from 363 in 1854. The South Wales coalfield had 63 collieries employing 48,000 men, down from 500 collieries and 250,000 men at its peak in 1913.

18 November 1965, The UK�s National Coal Board announced that 150 pits were to close over the next thre years, with some 120,000 job losses.

1 July 1965, The UK Government decided to write off $450 million of the National Coal Board�s capital debt and to start a programme to close uneconomic pits.

6 May 1965, The new modern mechanised colliery officially opened at Kellingly, Yorkshire, UK. It was already producing 3,000 tons of coal a week.

14 November 1950, Britain�s National Coal Board published the Plan For Coal. Demand was assumed to rise over the next 10-15 years and production would be expanded by 20%; some 250 of Britain�s 900 collieries would be comprehensively modernised. By the 1960s some 20 new super-collieries would be opened, and some 350-400 smaller ones closed, mainly in central Scotland, west Durham, Lancashire, Cannock Chase and the Forest of Dean.

30 June 1950, It was announced that the National Coal Board made a profit of �9.5 million in 1949.

13 July 1948, It was announced that the UK coal industry lost �13 million in its first year of nationalisation.

7 May 1947, Explosion at a coal mine in Barnsley, Yorkshire, UK, killed 9 miners.

1 January 1947. Britain�s coal industry was nationalised under the Coal industry Nationalisation Act, 1946. The National Coal Board (NCB) was set up, to control 1,647 mines, 100,000 miners homes and over a million acres of land. The NCB was chaired by Lord Hyndley.

3 June 1942, The UK Government announced plans to nationalise the coal mines.

19 December 1929, UK Parliament passed the Coal Mines Bill, It allocated quotas and provided for a 7 �hour day.

1 March 1927, Coal mine explosion in Ebbw Vale, Glamorgan, killed 50 and trapped 150 miners.

30 June 1925. The British mining industry faced a crisis. During 1923 and 1924 German coal exports had been halved because of French occupation of the Ruhr following a reparations dispute between France and Germany. Settlement of this, and a return to the Gold Standard by Britain at a rate which effectively raised UK export prices by 10% meant that in the first 6 months of 1925 the UK coal industry made a loss of �2.1 million. On 30 June 1925 the mine workers were given a month�s notice of the cancellation of a pay award made in 1924 and the option of returning to an 8 hour day or further wage cuts ranging from 13% to 38%. Even after the 1924 pay rise, miners� wages were very low, in real terms lower than they had been in 1914. The Miners Union rejected the pay cut and the longer hours. See 25 July 1925.

30 December 1913, Colliery explosion in South Wales, UK, killed 439 miners.

1920, The Cornish tin mining industry had almost vanished. In 1872 gunpowder had been replaced by dynamite, greatly increasing safety in the mines, and there was a Cornish tin mining boom in 1881, Nevertheless the world share of tin provided by Cornish mines had shrunk from 37% in 1860 to just 1.5% in 1920. Cheaper sources of tin had become available, first from Malaysia and Indonesia, then Australia, and finally Bolivia.

11 May 1910, An explosion at a coal mine in Whitehaven cut off 132 men underground. They had to be abandoned; in fact none of them probably survived the explosion anyway.

1906, The UK Coal Mines Regulation Act limited coal miners working day to 8 hoiurs.

11 July 1905, 124 miners died in a pit disaster in Glamorgan, south Wales.

19 May 1902, A coal mine explosion killed 216 miners at the Coal Creek Company, Fraterville, Tennessee.

24 May 1901, 78 miners died ina pit disaster in Caerphilly, Wales.

4 July 1893, 139 died in a colliery disaster at Thornhill, Dewsbuty, Yorkdshire.

1887, In Britain the Mines Act regulated blasting procedures and stipulated the provision of first aid and ambulance facilities for mines.

1882, Coal was proving hazardous to carry by ship; some 100 British ships with coal cargoes were being lost each year, up from around 70 in 1776. Some coal, especially from south Wales, gave off methane which could be ignited by ships lanterns. All coal, if loaded wet, could absorb moisture and oxygen and form unstable peroxides, which then broke down in exothermic reactions to cause spontaneous ignition.

1872, In Britain the Coal Mines Regulation Act made compulsory the use of fan ventilators, stronger timbering, wire ropes, improved winding machinery and better safety lamps.

1862, Mining legislation in Britain stipulated that every mine must have at least two shafts, to increase the chances of escape in an accident.

1851, In Britain the Royal School of Mines opened. By the 1860s it was also training mine inspectors and raising safety standards in the mining industry.

1850, In Britain, the Coal Mines Inspection Act provided for increased inspectors to report on safety and work conditions in mines. The Mines Regulation and Inspection Act 1860 increased further the number of inspectors and forbade children aged under 12 from working underground. See Child Welfare for more legislation curbing childrens� work in mines and factories.

29 May 1829, Sir Humphrey Davy, born 17 December 1778, inventor of the safety lamp (see 9 January 1816) died in Geneva.

9 January 1816. Sir Humphrey Davy�s safety lamp used in a coal mine for the first time.

31 October 1815, Sir Humphrey Davy patented the miner�s safety lamp. The metal gauze surrounding the flame dissipated heat and prevented the ignition of inflammable gases.

10 May 1815, John Nixon, English mining engineer who developed the coal trade between south Wales and the French navy, was born in Barlow, Durham (died 3 June 1899 in London).

1 October 1813, Following the explosion at Brandling Main colliery (15 May 1812) the Sunderland Society was formed, to promote mine safety.

15 May 1812, Mine explosion at Brandling Main (Felling) colliery, Sunderland. See 1 October 1813.

17 December 1778, Sir Humphrey Davy, inventor of the miner�s safety lamp, was born in Penzance (died 1829).He was the son of a woodcarver. He also discovered the elements sodium, calcium, barium, magnesium, potassium and strontium by passing electricity through molten metal compounds.

15 May 1765, James Watt invented the condenser, effectively trebling the energy output of the existing Newcomen steam pumps. The earlier Newcomen steam engine pumped steam into a cylinder, forcing back a piston; the cylinder was then sprayed with cool water, condensing the steam and creating a vacuum that pulled the piston back. Alternately heating and cooling the cylinder was inefficient. Watt�s idea was to attach a separate chamber off the main cylinder into which the steam could be allowed to enter, and cooled there by water, again creating the vacuum that pulled the piston back again. The main cylinder could be kept hot, saving considerable energy. The energy content of Britain�s coal reserves was effectively trebled.

1763, Pit ponies coming into use in British coal mines.

1712, The Newcomen steam engine began to be used to pump water out of mines (see 1698, 15 May 1765).

1700, To manufacture 1 tonne of iron, in pre-industrial times, required 10 hectares of forest to produce enough charcoal. The same amount of iron could be made with 5 tonnes of coal.

1698, An early steam pump, known as the �miner�s friend�, was designed by Thomas Newcomen to pump water out of mines. See 1712.

1658, Coal production at Newcastle on Tyne reached 529,000 tons a year, up from 33,000 tons in 1564. Much of England had been deforested by the use of wood as fuel, and now coal was the main substitute.

1640, Annual UK coal output was 2 million tons. Wood had become much scarcer since 1540, and coal was being substituted as a fuel. Wood was also more needed for the building of ships. However Britain�s road system was very poor and it cost as much to move a quantity of coal 3 miles as it did to mine it.However the cost of water transport was far less and coal could be moved 30 miles by sea for the cost of 1 mile by road. These economics had a big impact on Tyneside coal, which was sent by sea in large quantities south to London. As mining progressed, less accessible seams needed to be worked, and close to the River Tyne there was a limit imposed by water ingress. Mines needed to move away from the River, but then the high costs of road transport down to the docks came into play. However see 1882, hazards of shipping coal.

1598, 163,000 tons of coal a year were being shipped from Newcastle on Tyne to London.

1590, First recorded use of �dramways�, two parralell lines of wooden planks from a mine pithead to the nreast waterway, to ease the passage of ore or coal (see also Railways GB)

1564, 33,000 tons of coal were being shipped from Newcastle on Tyne to London

1 July 1507, The earliest records of coal-mining at Nailsea, near Bristol. Coal was being transported to Yatton for household fireplaces. By the late 19th century coal mining had died out south of Bristol as the industry migrated to the richer seams of south Wales.

1400, Coal was an unpopular domestic fuel, used only by those who lived close to a coal mine and were too poor to afford an alternatiuve fuel.

1259, The first(?) historical record of mining in England. King Henry III granted the freemen of Newcastle on Tyne a licence to dig for coals.

1183, A coal mine was recorded as existing at Escomb, near Durham.

Famous geologists, geological societies, geological theories

30 September 1985, Charles Richter, the US seismologist who devised the Richter Scale, died.

24 February 1978, Mary Leakey reported the discovery of fossil footprints made by bipedal hominids 3.6 million years ago.

28 October 1977, Elso Barghoorn and Andrew Knoll announced the discovery of 3.4 billion year old fossils of bacteria.

21 June 1977, Bruce Charles Heezen, US oceanographer and geologist, died near Reykjanes, Iceland.

17 February 1977, Scientists discovered thermal vents near the Galapagos Ridge, east Pacific.

1967, US and British geologists William Morgan, Dan McKenzie and Robert Parker combined Wegener�s 1912 theory of continental drift and the 1961 theory of ocean spreading to create a theory of plate tectonics, explaining mountain ranges, volcanoes, and earthquakes. The theory gained universal acceptance in the 1970s.

20 September 1965, Arthur Holmes, English geologist, died in London.

7 September 1963, Fred Vine and Drummond Matthews confirmed Harry Hess�s theory of sea floor spreading.

1961, US geologists Robert Dietz and Harry Hess independently theorised that sea floors spread apart as magma oozed up at central ridges. This went some way to explaining Wegener�s 1912 theory of continental drift. See 1967.

17 February 1942, Augusto Ponzio, semiologist was born in San Pietro Vernotico, Italy

18 December 1936, Andrija Mohorovicic, Croatian geologist, died in Zagreb.

16 October 1927, The first remnant of Peking Man, a tooth, was found by paleontologist Anders Birger Bohlin at Chou K'ou Tien (Zhoukoudian), under sponsorship of Davidson Black, who gave it the scientific name Sinanthropus pekinensis. More remains would be discovered over the next ten years, and reclassified as Homo erectus pekinensis, estimated to be more than 300,000 years old.

12 May 1913, William Maurice Ewing was born in Lockney, Texas. In 1935 he began a seismic study of the seabed using refractions of waves from explosions.

1912, German scientist Alfred Wegener proposed that all of the earth�s continents once formed one giant landmass. He based this on how they seemed to fit together like a jigsaw puzzle, and how similar fossil species could be observed on land,masses now far apart.however no-one could explain how the continents could actiually move.See 1961.
