Donning the pack by swinging it first from one shoulder to the other can involve twisting, which can result in excessive torque on the spine.
Friction between wellbore/casing and drill string causes excessive torque.
But a thicker mudcake can cause differential sticking, excessive torque and drag, etc.
Excessive torque is one of the most important problems in oil/gas drilling industry.
In both cases, the excessive torque of the engine on the rear wheel may cause the loss of control of the motorcycle.
Excessive torque and drag, difficulties in running casing in hole and accomplishing good cementing jobs and mechanical pipe sticking are few of the classical examples of such problems.
Although the duration of treatment with heavy rectangular wires and especially excessive torque application might be regarded as risk factors, no single mechanical factor can fully predict treatment-induced resorption of the root.
Their study highlighted that many fractures could be attributed to poor surgical techniques, referring to excessive torque on the humerus from reaming or external rotation manoeuvres intra-operatively [1, 7].
Although a thicker mudcake is beneficial for preventing lost circulation, it has several demerits, such as reducing the efficient well diameter, excessive torque and drag when rotating or pulling the drilling string, stuck pipe, etc.
On the other hand, although a thick mudcake can also help restrict fluid permeation, it may cause other drilling problems, such as stuck pipe and excessive torque and drag (Hashemzadeh and Hajidavalloo 2016; Ottesen et al. 1999; Outmans 1958).
But a thicker mudcake can cause differential sticking, excessive torque and drag, etc. (4) Even with a very thin mudcake (e.g., 2 mm), FIP can be effectively elevated compared with the case without mudcake on the wellbore.
