Wellheads control the production of oil or gas from the well, and can be used for water injection. They are mounted on production guidebases, which are the upper endpoint of the well casing at the seabed. A well head can be directly connected to a subsea manifold or indirectly via other wellheads, which may be arranged in groups called a subsea template. Most diving work on wellheads and manifolds is installation and maintenance.
|
|
Wellheads usually have a pressure rating of 5000 psi, 10,000 psi or 15,000 psi. These are far in excess of the other limits.
|
|
Subsea manifolds are structures mounted on the seabed where pipelines and connections to wellheads are connected to control the flow of product from the wells to their next destination. They will include valves and control mechanisms for the valves, and diving work mostly involves inspection and maintenance work, but can also include installation and repair, and connecting in new wellheads.

The resulting glory hole can be either open or cased. A cased glory hole utilizes steel casing as a retaining wall while an open glory hole is simply an excavation. Due to the cost of excavating individual glory holes, typically each glory hole will contain several wellheads. Locating multiple wellheads within a single glory hole is made possible by the use of directional drilling.

The importance of DHSVs is undisputed. Graphic images of oil wells in Kuwait on fire after the First Gulf War after their wellheads were removed, demonstrate the perils of not using the components (at the time, they were deemed unnecessary because they were onshore wells). It is, however, not a direct legal requirement in many places. In the United Kingdom, no law mandates the use of DHSVs.

The classical puteal is made of carved stone, often marble in Europe. They are frequently decorated with bas- reliefs of classical Greek and Roman themes around their outer faces. An Ancient Roman one was in the Puteal Scribonianum structure in the Roman Forum, nothing remains. The term is also used for circular classical remains (spolia) recycled after antiquity into wellheads, such as the Guildford Puteal at the British Museum.

22 The former is an intrafield pipeline, in the sense that it is used to connect subsea wellheads, manifolds and the platform within a particular development field. The latter, sometimes referred to as an "export pipeline", is used to bring the resource to shore. The construction and maintenance of marine pipelines imply logistical challenges that are different from those onland, mainly because of wave and current dynamics, along with other geohazards.

There are several methods used to detect fugitive gas emissions. Often, measurements are taken at wellheads, but it is also possible to measure emissions using an aircraft with specialized instruments on board. An aircraft survey in northeastern British Columbia indicated emissions emanating from approximately 47% of active wells in the area. The same study suggests that actual methane emissions may be much higher than what is being reported by industry or estimated by government.

These fires constituted approximately 50% of the total number of oil well fires in the history of the petroleum industry, and temporarily damaged or destroyed approximately 85% of the wells in every major Kuwaiti oil field. Concerted efforts to bring the fires and other damage under control began in April 1991. During the uncontrolled burning phase from February to April, various sources estimated that the ignited wellheads burnt through between four and six million barrels of crude oil, and between seventy and one hundred million cubic meters of natural gas per day.

Flooding in Kinshasa In many areas of the DRC, land use changes are associated with degradation of drinking water sources. The main threat to drinking water sources poses the unregulated growth of urban and rural areas. The nonexistence of drinking water protection zones results in the exposure of vulnerable source areas to pollution and land degradation. Springs, river intake zones, wellheads, priority lake and reservoir segments as well as aquifer recharge areas comprise the most endangered water source areas, which typically lack any form of identifiable demarcation and protection.

There are a wide range of production platforms which are chosen to suit the water depth, expected sea conditions and other constraints. Diving work will depend on the details, but will generally involve inspection, maintenance and repair of the structure, wellheads, manifolds, risers, associated pipelines and mooring systems. Divers may work on marine risers (conduits that extend a subsea oil well to a surface facility) and blowout prevention stacks on all production rig types if the depth is within diving range. Work may be surface oriented or in saturation depending on depth and duration.

MGE can trace its roots back to 1867 with the formation of the Kansas City Gas Light & Coke Company. Before pipeline technology was developed to deliver natural gas from wellheads to distant cities, gas was manufactured primarily from coal in a process that produced coal gas, more commonly known as coke, for lighting, cooking and heating. In 1895, the company was reorganized and became the Kansas City Gas Company. In 1897, the company merged with its chief competitor, the Missouri Gas Company, and became the Kansas City Missouri Gas Company, though it was still commonly called by its former name.

In 2006 Bluegrass created an underwater saw and had it patented for its use of hydraulic motors in combination with diamond wire to create a new sawing platform which was operational underwater. The continuous loop, four wheel drive diamond wire saw reduced cut times by providing greater torque and consistent wire grip. These improvements reduced slippage and subsequent wire breaks. Since then the patented underwater saw has been used domestically and globally on offshore decommissioning jobs including cutting single- and multi-string conductors, pipelines, seabed umbilicals, pilings, mooring chains, wellheads, risers, slot recovery and jacket lets.

When the well has been drilled, it is completed to provide an interface with the reservoir rock and a tubular conduit for the well fluids. The surface pressure control is provided by a Christmas tree, which is installed on top of the wellhead, with isolation valves and choke equipment to control the flow of well fluids during production. Wellheads are typically welded onto the first string of casing, which has been cemented in place during drilling operations, to form an integral structure of the well. In exploration wells that are later abandoned, the wellhead may be recovered for refurbishment and re-use.

Measurement and interpretation of 2 and 3 phase multiphase flow can also be achieved by using alternative flow measurement technologies such as SONAR. SONAR meters apply the principles of underwater acoustics to measure flow regimes and; can be clamped on to wellheads and flow lines to measure the bulk (mean) fluid velocity of the total mixture which is then post-processed and analyzed along with wellbore compositional information and process conditions to infer the flow rates of each individual phase. This approached can be used in various applications such as black oil, gas condensate and wet gas.

A glory hole in the context of the offshore petroleum industry is an excavation into the sea floor designed to protect the wellhead equipment installed at the surface of a petroleum well from icebergs or pack ice. An economically attractive alternative for exploiting offshore petroleum resources is a floating platform; however, ice can pose a serious hazard to this solution. While floating platforms can be built to withstand ice loading up to a design threshold, for the largest icebergs or the thickest pack ice the only sensible alternative is to move out of the way. Floating platforms can be disconnected from the wellheads in order to allow them to be moved away from threatening ice, but the wellhead equipment is fixed in place and hence vulnerable.

Ornamental wellhead (puteal) (1st century AD) depicting a drunken Hercules as part of a Bacchic revel Votive altar dedicated to the Divine Fontes (plural) Fontus or Fons (plural Fontes, "Font" or "Source") was a god of wells and springs in ancient Roman religion. A religious festival called the Fontinalia was held on October 13 in his honor. Throughout the city, fountains and wellheads were adorned with garlands.Stephen L. Dyson, Rome: A Living Portrait of an Ancient City (Johns Hopkins University Press, 2010), p. 228. Described by Varro, De lingua latina 6.3: "The Fontanalia [is named after] Fontus, because it's his holiday (dies feriae); on account of him then they toss wreaths into fountains and garland puteals" (Fontanalia a Fonte, quod is dies feriae eius; ab eo tum et in fontes coronas iaciunt et puteos coronant).

Allocation is an ongoing process based on flow or volume measurements, and gives the distribution of contributing sources, often with a final calculation per day, which in turn provides the basis for a daily production report in the case of a field that produces hydrocarbons. Moreover, the allocation process may be designed to split up a flow of multiple products of the individual ingredients or phase fractions, for example when associated gas and water are supplied with a crude oil flow, and each fraction within the commingled flow or storage is allocated between the contributors and its ownership. A traditional allocation practice will execute quantity calculations for crude oil, natural-gas condensate and produced water based on measured results from periodic, time-limited well tests. Natural gas flows from pure gas wells are usually measured continuously at or near the individual wellheads.

In 1991, the then-152nd Reconnaissance Group was among the first aircrew to fly missions over Kuwait and Iraq. They dodged anti-aircraft artillery, obtained photos of burning wellheads, spotted strategic targets and conducted assessments on the first morning of the war. Thirteen airmen of the unit received the Distinguished Flying Cross. Additionally, the 72nd Military Police deployed to Saudi Arabia where they operated and maintained prisoner of war camps. In 1995, the U.S. Air Force moved away from manned reconnaissance, and the 152nd re-designated as the 152nd Airlift Wing operating C-130 aircraft.“Nevada Air Guard marks 50 years of flight duty,” Reno Gazette- Journal, April 3, 1998; “Nevadans Given a Jolt as Air Guard is Called,” Nevada State Journal, Jan. 26, 1968; “Remembers the Past, Preparing for the Future,” Nevada Air National Guard’s 50th anniversary yearbook, 69. 1st Sgt.
