Louann Salt
The Louann Salt is a widespread evaporite formation that formed in the Gulf of Mexico during the Callovian in the mid Jurassic. The Louann formed in a rift as the South American and North American Plates separated, from an embayment of the Pacific Ocean. The Louann underlies much of the northern Gulf coast from Texas to the Florida panhandle and extends beneath large areas of the Gulf coastal plain of Mississippi, Louisiana and Texas.Hyne, Norman J., ''Nontechnical guide to petroleum geology, exploration, drilling, and production,'' Pennwell Books, 2nd ed. p. 193 The Campeche Salt or Isthmian Salt is the contemporaneous salt layer that developed on the south margin of the Gulf rift. It extends from Campeche, Mexico north along the west margin of the Campeche Bank north of the Yucatan Peninsula. The Orca Basin is a distinctive brine pool on the Louisiana continental shelf. One of the many salt domes derived from the Louann was the site of the Spindletop oil strike near Beaumo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Campeche
Campeche (; yua, Kaampech ), officially the Free and Sovereign State of Campeche ( es, Estado Libre y Soberano de Campeche), is one of the 31 states which make up the 32 Federal Entities of Mexico. Located in southeast Mexico, it is bordered by the states of Tabasco to the southwest, Yucatán to the northeast, and Quintana Roo to the east; to the southeast by the Orange Walk district of Belize, and by the Petén department of Guatemala to the south. It has a coastline to the west with the Gulf of Mexico. The state capital, also called Campeche, was declared a World Heritage Site in 1997. The formation of the state began with the city, which was founded in 1540 as the Spanish began the conquest of the Yucatán Peninsula. The city was a rich and important port during the colonial period, but it declined after Mexico's independence. Campeche was part of the province of Yucatán but split off in the mid-19th century, mostly due to political friction with the city of Mérida. Much ...

Petroleum Geology
Petroleum geology is the study of origin, occurrence, movement, accumulation, and exploration of hydrocarbon fuels. It refers to the specific set of geological disciplines that are applied to the search for hydrocarbons (oil exploration). Sedimentary basin analysis Petroleum geology is principally concerned with the evaluation of seven key elements in sedimentary basins: * Source * Reservoir * Seal * Trap * Timing * Maturation * Migration In general, all these elements must be assessed via a limited 'window' into the subsurface world, provided by one (or possibly more) exploration wells. These wells present only a 1-dimensional segment through the Earth, and the skill of inferring 3-dimensional characteristics from them is one of the most fundamental in petroleum geology. Recently, the availability of inexpensive, high quality 3D seismic data (from reflection seismology) and data from various electromagnetic geophysical techniques (such as magnetotellurics) has greatly aide ...

Petroleum
Petroleum, also known as crude oil, or simply oil, is a naturally occurring yellowish-black liquid mixture of mainly hydrocarbons, and is found in geological formations. The name ''petroleum'' covers both naturally occurring unprocessed crude oil and petroleum products that consist of refined crude oil. A fossil fuel, petroleum is formed when large quantities of dead organisms, mostly zooplankton and algae, are buried underneath sedimentary rock and subjected to both prolonged heat and pressure. Petroleum is primarily recovered by oil drilling. Drilling is carried out after studies of structural geology, sedimentary basin analysis, and reservoir characterisation. Recent developments in technologies have also led to exploitation of other unconventional reserves such as oil sands and oil shale. Once extracted, oil is refined and separated, most easily by distillation, into innumerable products for direct use or use in manufacturing. Products include fuels such as gasol ...

Spindletop
Spindletop is an oil field located in the southern portion of Beaumont, Texas, in the United States. The Spindletop dome was derived from the Louann Salt evaporite layer of the Jurassic geologic period. On January 10, 1901, a well at Spindletop struck oil ("came in"). The Spindletop gusher blew for 9 days at a rate estimated at of oil per day., Texas State Historical Association Gulf Oil and Texaco, now part of Chevron Corporation, were formed to develop production at Spindletop. The Spindletop discovery led the United States into the oil age. Prior to Spindletop, oil was primarily used for lighting and as a lubricant. Because of the quantity of oil discovered, burning petroleum as a fuel for mass consumption suddenly became economically feasible. The frenzy of oil exploration and the economic development it generated in the state became known as the Texas oil boom. The United States soon became the world's leading oil producer. __TOC__ History Pattillo Higgins sought a so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salt Dome
A salt dome is a type of structural dome formed when salt (or other evaporite minerals) intrudes into overlying rocks in a process known as diapirism. Salt domes can have unique surface and subsurface structures, and they can be discovered using techniques such as seismic reflection. They are important in petroleum geology as they can function as petroleum traps. Formation Stratigraphically, salt basins developed periodically from the Proterozoic to the Neogene. The formation of a salt dome begins with the deposition of salt in a restricted basin. In these basins, the outflow of water exceeds inflow. More concretely, the basin loses water through evaporation, resulting in the precipitation and deposition of salt. While the rate of sedimentation of salt is significantly larger than the rate of sedimentation of clastics, it is recognized that a single evaporation event is rarely enough to produce the vast quantities of salt needed to form a layer thick enough for the formation ...

Continental Shelf
A continental shelf is a portion of a continent that is submerged under an area of relatively shallow water, known as a shelf sea. Much of these shelves were exposed by drops in sea level during glacial periods. The shelf surrounding an island is known as an ''insular shelf''. The continental margin, between the continental shelf and the abyssal plain, comprises a steep continental slope, surrounded by the flatter continental rise, in which sediment from the continent above cascades down the slope and accumulates as a pile of sediment at the base of the slope. Extending as far as 500 km (310 mi) from the slope, it consists of thick sediments deposited by turbidity currents from the shelf and slope. The continental rise's gradient is intermediate between the gradients of the slope and the shelf. Under the United Nations Convention on the Law of the Sea, the name continental shelf was given a legal definition as the stretch of the seabed adjacent to the shores of a par ...

Brine Pool
A brine pool, sometimes called an underwater lake, deepwater or brine lake, is a volume of brine collected in a seafloor depression. The pools are dense bodies of water that have a salinity that is three to eight times greater than the surrounding ocean. Brine pools are commonly found below polar sea ice and in the deep ocean. Those below sea ice form through a process called brine rejection. For deep-sea brine pools, salt is necessary to increase the salinity gradient. The salt can come from one of two processes: the dissolution of large salt deposits through salt tectonics or geothermally heated brine issued from tectonic spreading centers. The brine often contains high concentrations of hydrogen sulfide and methane, which provide energy to chemosynthetic organisms that live near the pool. These creatures are often extremophiles and symbionts. Deep-sea and polar brine pools are toxic to marine animals due to their high salinity and anoxic properties, which can ultimately lead ...
