mr.wicks Drilling, 2017-09-17 17:50:28. Large truck drills can use over 570 litres (150 US gal) of fuel per day, while the smaller Deeprock Style portable drills use a mere 20 to 75 litres (5 to 20 US gal) of fuel per day. This makes smaller, more portable rigs preferable in remote or hard-to-reach places, and they are more cost effective when fuel prices are high.

mr.wicks Drilling, 2017-09-17 17:53:24. There are a variety of drill mechanisms which can be used to sink a borehole into the ground. Each has its advantages and disadvantages, in terms of the depth to which it can drill, the type of sample returned, the costs involved and penetration rates achieved. There are two basic types of drills: drills which produce rock chips, and drills which produce core samples.

mr.wicks Drilling, 2017-09-17 17:36:19. RC drilling proved much faster and more efficient, and continues to improve with better metallurgy, deriving harder, more durable bits, and compressors delivering higher air pressures at higher volumes, enabling deeper and faster penetration. Diamond drilling has remained essentially unchanged since its inception.

mr.wicks Drilling, 2017-09-17 17:25:56. Small to medium-sized drilling rigs are mobile, such as those used in mineral exploration drilling, blast-hole, water wells and environmental investigations. Larger rigs are capable of drilling through thousands of metres of the Earth s crust, using large "mud pumps" to circulate drilling mud (slurry) through the drill bit and up the casing annulus, for cooling and removing the "cuttings" while a well is drilled.

Archaeological evidence of the drilling tools used in deep-well dwelling are kept and displayed in the Zigong Salt Industry Museum.[2] According to Salt: A World History, a Qing Dynasty well, also located in Zigong, "continued down to 3,300 feet [1,000 m] making it at the time the deepest drilled well in the world."[3] Mechanised versions of this system persisted until about 1970, using a cam to rapidly raise and drop what, by then, was a steel cable up to 3 mm.
