· However, in fractured formations, borehole breakout and rock slip may occur along weak planes and discontinuities during drilling (Zhang, 2013). Karatela et al. (2016) proposed that shear failure along weak planes is the main failure mode of the wellbore at a depth of 1500 m in the Cooper Basin, Australia.

· Mud rotary drilling is a common method used in the oil and gas industry to drill boreholes into the earth. It is a form of rotary drilling that utilizes a drilling fluid, known as mud, to cool and lubricate the drill bit, as well as to remove the cuttings from the borehole. The process of mud rotary drilling involves several steps.

Borehole. A borehole is a narrow shaft bored in the ground, either vertically or horizontally. A borehole may be constructed for many different purposes, including the extraction of water ( drilled water well and tube well ), other liquids (such as petroleum ), or gases (such as natural gas ). It may also be part of a geotechnical investigation

A drilling rig is a type of construction equipment used to make holes in the earth’s surface. They can vary considerably in size: they can be massive structures or light enough to be moved manually by a single person. Drilling rigs can take samples from mineral deposits as well as test the physical properties of rocks, soil and groundwater.

Normal rotary drilling is the rotation of a cutting bit on the end of a length of drill stem in which the downward pressure behind the cutting edge abrades the rock face.
