Dating someone who works on an oil rig
Small mobile drilling rigs are also used to drill or bore piles.Rigs can range from 100 ton continuous flight auger (CFA) rigs to small air powered rigs used to drill holes in quarries, etc.Auger drilling is done with a helical screw which is driven into the ground with rotation; the earth is lifted up the borehole by the blade of the screw.Hollow stem auger drilling is used for softer ground such as swamps where the hole will not stay open by itself for environmental drilling, geotechnical drilling, soil engineering and geochemistry reconnaissance work in exploration for mineral deposits.Other equipment can force acid or sand into reservoirs to facilitate extraction of the oil or natural gas; and in remote locations there can be permanent living accommodation and catering for crews (which may be more than a hundred).Marine rigs may operate thousands of miles distant from the supply base with infrequent crew rotation or cycle.
Some types included are Rotary cut, Rotary Abrasive, Rotary Reverse, Cable Tooling, and Sonic Drilling.
Typically this is done when changing a drill bit or when "logging" the well.
A single joint of pipe is typically some 30 feet long.
Oil and natural gas drilling rigs are used not only to identify geologic reservoirs but also to create holes that allow the extraction of oil or natural gas from those reservoirs.
Primarily in onshore oil and gas fields once a well has been drilled, the drilling rig will be moved off of the well and a service rig (a smaller rig) that is purpose-built for completions will be moved on to the well to get the well on line. Mining drilling rigs are used for two main purposes, exploration drilling which aims to identify the location and quality of a mineral, and production drilling, used in the production-cycle for mining.
A drilling rig is an integrated system that drills wells, such as oil or water wells, in the earth's subsurface.
