Slide bit feed is often used in the drilling of directional and horizontal wells. How the surface intermittently feeding of drill pipe into the well transfers to down hole drill bit pushing? How to reduce the WOB error due to slide friction between t

The article presents a procedure to calculate fluid pressure losses in hole drilling with units equipped with replaceable core tubes and using non-Newtonian mud fluids. It is found that main hydraulic loss takes place when mud fluid flows in clearing

A specially structured drill bit is designed for a reverse circulation down-the-hole air hammer to reduce dust production in the local vicinity of the drilling site during operation. Computational fluid dynamics and experimental studies were conducte

The drill bit, which directly transmits percussive forces and torque to the rock, is the core part of a rock drilling machine. For effective drilling, the button arrangement of a drill bit should be optimized because it is the most important design f

This paper seeks to demonstrate how the use of real-time downhole drilling data can help facilitate the timely, well-informed decision to pull out of hole (POOH) if the rate of penetration (ROP) reduces beyond expectation. The traditional decision pr

Deep-hole drilling is a process in which the hole length will be very high when compared to diameter of the drill hole (i.e. length to diameter ratio will be greater than 5). Drilling a deep hole with very high accuracy is difficult process. The curr
