In addition, Mr. Freeze would be the second highest attraction at Six Flags Over Texas, with the tallest being the park's Oil Derrick observation tower.

A-frame derrick. An A-frame derrick is one in which the boom is hinged from a cross member between the bottom ends of two upright members spread apart at the lower ends and joined at the top; the boom point secured to the junction of the side members, and the side members are braced or guyed from this junction point.
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 ...

A derrick and pumpjack do not look even vaguely similar, nor do they have the same function.
On May 14, 1922, an oil drilling crew completed a 2,000 feet (610 m) well, dubbed J.T. Murphy No. 1, and began pumping. The early production was entirely natural gas, which began escaping from the drill collar. Eventually it caught fire, burning for several hours, and destroying the derrick. It also caused a series of violent underground ...
