Lower Riser Package
The Lower Riser Package is a mechanical device to protect an oil well located underwater (subsea) and used during an oil well intervention. The LRP is essentially a mini blow out preventer (BOP). The lower riser package consists of a connector to the subsea oil well, a series of safety valves and a connection point at the top for connection to the riser pipe. The riser pipe is essentially a mini Marine riser and has a maximum inside diameter of 7 inches. A marine riser has a maximum inside diameter of 19 inches. The LRP is used within what is called a workover system. A workover system is basically a series of valves and high strength pipe connecting a floating drilling rig to the subsea Christmas tree A Christmas tree is a decorated tree, usually an evergreen conifer, such as a spruce, pine or fir, or an artificial tree of similar appearance, associated with the celebration of Christmas.

Blow-out Preventer
A blowout preventer (BOP) (pronounced B-O-P, not "bop") is a specialized valve or similar mechanical device, used to seal, control and monitor oil and gas wells to prevent blowouts, the uncontrolled release of crude oil or natural gas from a well. They are usually installed in stacks of other valves. Blowout preventers were developed to cope with extreme erratic pressures and uncontrolled flow ( formation kick) emanating from a well reservoir during drilling. Kicks can lead to a potentially catastrophic event known as a blowout. In addition to controlling the downhole (occurring in the drilled hole) pressure and the flow of oil and gas, blowout preventers are intended to prevent tubing (e.g. drill pipe and well casing), tools and drilling fluid from being blown out of the wellbore (also known as bore hole, the hole leading to the reservoir) when a blowout threatens. Blowout preventers are critical to the safety of crew, rig (the equipment system used to drill a wellbore) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Drilling Rig (petroleum)
This article lists the main components of a petroleum onshore drilling rig. Offshore drilling rigs have similar elements, but are configured with a number of different drilling systems to suit drilling in the marine environment. The equipment associated with a rig is to some extent dependent on the type of rig but typically includes at least some of the items listed below. {{clear List of items #Mud tank #Shale shakers # Suction line (mud pump) #Mud pump #Motor or power source #hose #Drawworks # Standpipe #Kelly hose # Goose-neck # Traveling block # Drill line #Crown block #Derrick # Racking Board (Sometimes referred to as the Monkey Board) #Stand (of drill pipe) # Setback (floor) #Swivel (On newer rigs this may be replaced by a top drive) #Kelly drive #Rotary table #Drill floor #Bell nipple #Blowout preventer (BOP) Annular type #Blowout preventer (BOP) Pipe ram & blind ram #Drill string #Drill bit #Casing head or Wellhead #Flow line Explanation *Bell nipple (#22) is a sectio ...

Christmas Tree (oil Well)
In petroleum and natural gas extraction, a Christmas tree, or "tree", is an assembly of valves, casing spools, and fittings used to regulate the flow of pipes in an oil well, gas well, water injection well, water disposal well, gas injection well, condensate well, and other types of well. Overview The first primitive Christmas Tree was used by the Hamill Brothers to bring Spindletop under control. It consisted of a T-valve, with a and valve on the vertical pipe, and a 6-inch valve on the horizontal pipe. The vertical valve was closed first, and then the valve to the horizontal pipe. Christmas trees are used on both surface and subsea wells. It is common to identify the type of tree as either "subsea tree" or "surface tree". Each of these classifications has a number of variations. Examples of subsea include conventional, dual bore, mono bore, TFL (through flow line), horizontal, mudline, mudline horizontal, side valve, and TBT (through-bore tree) trees. The deepest install ...
