The drill bit on a turbodrill spins much faster than on a conventional motor drill. The result is that, though there is less torque, this is compensated for by the increased speed, which makes straighter holes, and can drill faster and easier through tougher ground materials. The process is very similar to a dental drill used by a dentist.
The first known patent application is from Christopher G. Cross in 1873 for "Drills for Boring Artesian Wells", [1] followed in 1884 by the brothers Morris and Clarence Baker for a "Machine for Operating Drills" [2] The methods used to direct the well path fall into two broad categories, these being “push-the-bit” or “point-the-bit ...

Drilling engineering is a subset of petroleum engineering. [1] Drilling engineers design and implement procedures to drill wells as safely and economically as possible. [1] They work closely with the drilling contractor, service contractors, and compliance personnel, as well as with geologists and other technical specialists.
In one arrangement, the motor has an ordinary stator. A squirrel-cage rotor connected to the output shaft rotates within the stator at slightly less than the rotating field from the stator. Within the squirrel-cage rotor is a freely rotating permanent magnet rotor, which is locked in with rotating field from the stator.
Normal mud motor construction consists of a top sub, which connects the mud motor to the drill string; the power section, which consists of the rotor and stator; the transmission section, where the eccentric power from the rotor is transmitted as concentric power to the bit using a constant-velocity joint; the bearing assembly which protects the tool from off bottom and on bottom pressures ...
Various machine components used in mechanical engineering. Mechanical engineering is the study of physical machines that may involve force and movement. It is an engineering branch that combines engineering physics and mathematics principles with materials science, to design, analyze, manufacture, and maintain mechanical systems. [1]
Automotive engineering – Automotive engineering, along with aerospace engineering and marine engineering, is a branch of vehicle engineering, incorporating elements of mechanical, electrical, electronic, software and safety engineering as applied to the design, manufacture and operation of motorcycles, automobiles and trucks and their ...
