Directional drilling is done with a mud motor on the Bottom hole assembly (BHA).The direction is controlled by wireless controller to drill the hole in any way that the driller requires. There are a variety of drilling techniques which can be used to drill a borehole into the ground.There are many types and designs of drilling rigs, with many drilling rigs capable of switching or combining different drilling technologies as needed.Drilling rigs can be described using any of the following attributes: Rigs are differentiated by height based on how many connected joints of drill pipe they are able to "stand" in the derrick when it is out of the hole.Until internal combustion engines were developed in the late 19th century, the main method for drilling rock was muscle power of man or animal.The technique of oil drilling through percussion or rotary drilling has its origins dating back to the ancient Chinese Han Dynasty in 500 BC, where percussion drilling was used to extract natural gas in the Sichuan province.
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.
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 manually by one person and such are called augers.
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.
