2013912 Rotary Mud Drilling Rotary mud drilling is most often used for deep stratigraphic drilling in coal exploration. This method produces fine rock fragments and uses water and drilling fluids to lubricate the drill bit and bring the rock fragments to the surface. Typically a
RC drilling ideally produces dry rock chips as large air compressors dry the rock out ahead of the advancing drill bit. RC drilling is slower and costlier but achieves better penetration than RAB or air core drilling; it is cheaper than diamond coring and is thus preferred for most mineral exploration work.

To drill with a mud motor rotating the bit downhole without rotating the drillstring from the surface. This operation is conducted when the bottomhole assembly has been fitted with a bent sub or a bent housing mud motor or both for directional drilling. Sliding is the predominant method to build and control or correct hole angle in modern directional drilling operations.

A rig rated for 18000 ft of drilling may not be capable of running 15000 ft of heavy 9⅝in. casing. Therefore the well plan must be developed and analyed before rig selection. Rig costs vary considerably and are dependent on items such as supply and demand rig characteristics and standard items found on the rig.
A rig would be counted even if it is down and inactive or up and active. It is a definitive measure of understanding the drilling status of an oil well. This counting process of drilling rigs can also provide an insight to data such as the type and volume of oil or gas produced well depth production drilling
2019714 For many years percussion drilling was the primary method used to drill oil and geothermal wells. In recent years rotary drills have become more common because they are quicker and are not limited to vertical holes as percussion cable drills are. They still have a place however in some geothermal production ones.
