Large derricks mounted on dedicated vessels are known as floating derricks [4] and shearlegs. The term derrick is also applied to the framework supporting a drilling apparatus in an oil rig. [5] The derrick derives its name from a type of gallows named after Thomas Derrick, an Elizabethan era English executioner. [6]
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 boom in the oil industry also helped promote other industries in other areas of the state. Lumber production thrived as demand climbed for construction of railroads, refineries, and oil derricks, and, in 1907, Texas was the third largest lumber producer in the United States.
On May 24, 1920, the first Huntington Beach well, the Huntington A-1 3] was brought in as a producing well By October 1921, the field had 59 producing wells. [4] Even with 16 of those 59 wells being idle, the field produced 16,500 barrels of oil equivalent (101,000 GJ) per day, with each well producing from 50 to 200 barrels daily.
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 Six Flags Over Texas Oil Derrick is a 300-foot (91 m) tall observation tower, and an attraction at the theme park Six Flags Over Texas.Six Flags claims it to be the world's tallest land-based oil derrick (although it is actually not functional as such, and never has been).
The East Texas Oil Field is a large oil and gas field in east Texas. Covering 140,000 acres (57,000 ha) and parts of five counties, and having 30,340 historic and active oil wells, it is the second-largest oil field in the United States outside Alaska, and first in total volume of oil recovered since its discovery in 1930.

Heavy iron bits were attached to long bamboo cables suspended from bamboo derricks and then were repeatedly raised and dropped into a manually dug hole by having two to six men jumping on a lever. [1] Han dynasty oil wells made by percussion drilling was effective but only reached 10 meters deep and 100 meters by the 10th century. [1]
