Timeline Of The Deepwater Horizon Oil Spill
The following is a timeline of the Deepwater Horizon oil spill, ''Deepwater Horizon'' oil spill (also referred to as the BP oil spill, the Gulf of Mexico oil spill or the Macondo blowout). It was a massive oil spill in the Gulf of Mexico, the largest offshore spill in U.S. history. It was a result of the well blowout that began with the Deepwater Horizon drilling rig explosion, ''Deepwater Horizon'' drilling rig explosion on April 20, 2010. Background 2008 *March 2008 – The mineral rights to drill for oil at the Macondo Prospect, Macondo well, located in Mississippi Canyon Block 252 in the United States sector of the Gulf of Mexico about off the Louisiana coast, were purchased by BP at the Minerals Management Service's (MMS) Lease Sale No. 206, held in New Orleans. 2009 *February – BP files a 52-page exploration and environmental impact plan for the Macondo Prospect, Macondo well with the MMS. The plan stated that it was "unlikely that an accidental surface or subsurface oi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deepwater Horizon Oil Spill
The ''Deepwater Horizon'' oil spill (also referred to as the "BP oil spill") was an industrial disaster that began on 20 April 2010 off of the coast of the United States in the Gulf of Mexico on the BP-operated Macondo Prospect, considered to be the largest marine oil spill in the history of the petroleum industry and estimated to be 8 to 31 percent larger in volume than the previous largest, the Ixtoc I oil spill, also in the Gulf of Mexico. The United States federal government estimated the total discharge at . After several failed efforts to contain the flow, the well was declared sealed on 19 September 2010. Reports in early 2012 indicated that the well site was still leaking. The ''Deepwater Horizon'' oil spill is regarded as one of the largest environmental disasters in world history. A massive response ensued to protect beaches, wetlands and estuaries from the spreading oil utilizing skimmer ships, floating booms, controlled burns and of oil dispersant. Due to ...

Subsea (technology)
Subsea technology involves fully submerged ocean equipment, operations, or applications, especially when some distance offshore, in deep ocean waters, or on the seabed. The term ''subsea'' is frequently used in connection with oceanography, marine or ocean engineering, ocean exploration, remotely operated vehicle (ROVs) autonomous underwater vehicles (AUVs), submarine communications or power cables, seafloor mineral mining, oil and gas, and offshore wind power. Oil and gas Oil and gas fields reside beneath many inland waters and offshore areas around the world, and in the oil and gas industry the term ''subsea'' relates to the exploration, drilling and development of oil and gas fields in these underwater locations. Under water oil fields and facilities are generically referred to using a ''subsea'' prefix, such as ''subsea well'', ''subsea field'', ''subsea project'', and ''subsea developments.'' Subsea oil field developments are usually split into ''Shallow water'' and ''Deep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oil Sheen
An oil is any nonpolar chemical substance that is composed primarily of hydrocarbons and is hydrophobic (does not mix with water) & lipophilic (mixes with other oils). Oils are usually flammable and surface active. Most oils are unsaturated lipids that are liquid at room temperature. The general definition of oil includes classes of chemical compounds that may be otherwise unrelated in structure, properties, and uses. Oils may be animal, vegetable, or petrochemical in origin, and may be volatile or non-volatile. They are used for food (e.g., olive oil), fuel (e.g., heating oil), medical purposes (e.g., mineral oil), lubrication (e.g. motor oil), and the manufacture of many types of paints, plastics, and other materials. Specially prepared oils are used in some religious ceremonies and rituals as purifying agents. Etymology First attested in English 1176, the word ''oil'' comes from Old French ''oile'', from Latin ''oleum'', which in turn comes from the Greek (''elaion'') ...

Cement Bond Log
A cement bond log documents the evaluation of the integrity of cement work performed on an oil well. In the process of drilling and completing a well, cement is injected through the wellbore and rises up the annulus between the steel casing and the formation. A sonic tool is typically run on wireline by a service company that detects the bond of the cement to the casing and formation via a principle based on resonance. Casing that is not bound has a higher resonant vibration than that which is bound, causing the imparted energy from the sonic signal to be transferred to the formation. In this sense, the amplitude The amplitude of a periodic variable is a measure of its change in a single period (such as time or spatial period). The amplitude of a non-periodic signal is its magnitude compared with a reference value. There are various definitions of ampl ... of the waveform received is the basic measurement that is evaluated.

Drilling Mud
In geotechnical engineering, drilling fluid, also called drilling mud, is used to aid the drilling of boreholes into the earth. Often used while drilling oil and natural gas wells and on exploration drilling rigs, drilling fluids are also used for much simpler boreholes, such as water wells. One of the functions of drilling mud is to carry cuttings out of the hole. The three main categories of drilling fluids are: water-based muds (WBs), which can be dispersed and non-dispersed; non-aqueous muds, usually called oil-based muds (OBs); and gaseous drilling fluid, in which a wide range of gases can be used. Along with their formatives, these are used along with appropriate polymer and clay additives for drilling various oil and gas formations. The main functions of drilling fluids include providing hydrostatic pressure to prevent formation fluids from entering into the well bore, keeping the drill bit cool and clean during drilling, carrying out drill cuttings, and susp ...

Cementing Equipment
Oil Well Cementing Equipment are essential for the Oil/Gas exploration or production wells and are must used oilfield equipments while drilling a well. Casing pipe will be installed at various depths while drilling. It is held in place by cement, which also provides zone isolation. Casing is run to protect the wellbore A borehole is a narrow shaft bored in the ground, either vertically or horizontally. A borehole may be constructed for many different purposes, including the extraction of water ( drilled water well and tube well), other liquids (such as petr ... from fluids, pressures and wellbore stability problems. Down-hole equipment such as Centralizers and Turbolizers are used to ensure obtaining satisfactory zone isolation. Float Shoes and Collars ( float valves) prevent backflow after the cement has been pumped into place.

Casing (borehole)
Casing is a large diameter pipe that is assembled and inserted into a recently drilled section of a borehole. Similar to the bones of a spine protecting the spinal cord, casing is set inside the drilled borehole to protect and support the wellstream. The lower portion (and sometimes the entirety) is typically held in place with cement. Deeper strings usually are not cemented all the way to the surface, so the weight of the pipe must be partially supported by a casing hanger in the wellhead. Casing that is cemented in place aids the drilling process in several ways: * Prevents contamination of fresh water well zones. * Prevents unstable upper formations from caving in and sticking the drill string or forming large caverns. * Provides a strong upper foundation to allow use of high-density drilling fluid to continue drilling deeper. * Isolates various zones, which may have different pressures or fluids, in the drilled formations from one another. * Seals off high pressure zone ...
