The pipe hitch will not slip when tied correctly to a pipe or pole. This knot is a variation of the Round turn and two half-hitches. [4] [5] This knot can be used with a rope to pull a pipe or spar out of the ground, [6] or to hoist a pipe or beam.
Tripping pipe (or "Making a round trip" or simply "Making a trip") is the physical act of pulling the drill string out of the wellbore and then running it back in. This is done by physically breaking out or disconnecting (when pulling out of the hole) every other 2 or 3 joints of drill pipe at a time (called a stand ) and racking them ...
A drilling rig is an integrated system that drills wells, such as oil or water wells, or holes for piling and other construction purposes, into the earth's subsurface. Drilling rigs can be massive structures housing equipment used to drill water wells , oil wells , or natural gas extraction wells, or they can be small enough to be moved ...
A short video recording of such a pump in action can be viewed on YouTube. [ 6 ] Although the flow rate for a water well pumpjack is lower than that from a jet pump and the lifted water is not pressurised, the beam pumping unit has the option of hand pumping in an emergency, by hand-rotating the pumpjack cam to its lowest position, and ...
A drum hoist (steel wire rope visible) and motor. In underground mining a hoist or winder [1] is used to raise and lower conveyances within the mine shaft.Modern hoists are normally powered using electric motors, historically with direct current drives utilizing Ward Leonard control machines and later solid-state converters (), although modern large hoists use alternating current drives that ...
Well drilling is the process of drilling a hole in the ground for the extraction of a natural resource such as ground water, brine, natural gas, or petroleum, for the injection of a fluid from surface to a subsurface reservoir or for subsurface formations evaluation or monitoring.
A shadoof or shaduf, [1] well pole, well sweep, sweep, [2] swape, [3] or simply a lift [4] is a tool that is used to lift water from a well or another water source onto land or into another waterway or basin. It is highly efficient, and has been known since 3000 BCE.
Pull the drillstring to the pipe's neutral weight, which is the combined weight of blocks and the weight of the drill string and make a mark(X 1)(in) at the top of the rotary table. Identify the recommended overpull by multiplying 2208.5 by pipe weight/ft. Pull the calculated overpull(F) (Not to exceed the yield strength of the pipe) causing ...
