Two guy derricks at a granite quarry. A derrick is a lifting device composed at minimum of one guyed mast, as in a gin pole, which may be articulated over a load by adjusting its guys. Most derricks have at least two components, either a guyed mast or self-supporting tower, and a boom hinged at its base to provide articulation, as in a stiffleg ...
Racking board (#15) is the catwalk along the side of the derrick (usually about 35 or 40 feet above the "floor"). The monkey board is where the derrick man works while "tripping" pipe. Mud motor (not pictured) is a hydraulically powered device positioned just above the drill bit used to spin the bit independently from the rest of the drill string.
The arrangement is often used for onshore wells. Pumpjacks are common in oil-rich areas. Depending on the size of the pump, it generally produces 5 to 40 litres (1 to 9 imp gal; 1.5 to 10.5 US gal) of liquid at each stroke. Often this is an emulsion of crude oil and water. Pump size is also determined by the depth and weight of the oil to ...
Discovered in 1921, the field was enormously productive in the 1920s, with hundreds of oil derricks covering Signal Hill and adjacent parts of Long Beach; largely due to the huge output of this field, the Los Angeles Basin produced one-fifth of the nation's oil supply during the early 1920s. In 1923 alone the field produced over 68 million ...
The term "oil derrick" has been removed from the list of "also known as" terms, since these are two different things. An oil derrick is a steel framework tower used in drilling and servicing oil wells; it is removed when the well is being pumped. A derrick and pumpjack do not look even vaguely similar, nor do they have the same function.
Left Coast Lifter is a floating derrick barge or sheerleg which was built to assist in the eastern span replacement of the San Francisco–Oakland Bay Bridge.The barge carries a shear legs crane which is the largest barge crane ever used on the U.S. West Coast.
Stands are emplaced on the floor of the drilling rig by the chain hand. When stands are being put onto the floor the chainhand is said to be "racking stands". After the bottom of the stand is placed on the floor, the derrickman will unlatch the elevators and pull the stand in either with a rope or with just his arms.
The Route 66 Historical Village at 3770 Southwest Boulevard in Tulsa, Oklahoma, is an open-air museum along historic U.S. Route 66 (US 66, Route 66). [1] The village includes a 194-foot-tall (59 m) oil derrick at the historic site of the first oil strike in Tulsa on June 25, 1901, which helped make Tulsa the "Oil Capital of the World". [1]
