Abstract: Drill-string vibration has a great negative influence on the safety and efficiency of geological drilling. Noticing that the influence of drill-string inclination is not well considered in ...

One of the most effective ways of reducing downtime on projects using compact and medium-sized horizontal directional drilling (HDD) units is to properly maintain drill-string components—drill pipe, ...

Abstract: During the engineering of horizontal well, drill string is in the complicated moving state, strong vibration is the main reason that induces drill string failure. Drill string vibrations ...

Epiroc has released Epiroc ET66, ET45, and ET38 drill strings, marking a substantial breakthrough in tophammer drilling efficiency and reliability. Developed over five years, the new Epiroc ET drill ...

Halliburton has released the DynaTrac™ Real-Time Wireless Depth Correlation System, a new technology that reduces uncertainty and saves rig time by enabling operators to accurately position packers, ...

A drill bit is what actually cuts into the rock when drilling an oil or gas well. Located at the tip of the drillstring, below the drill collar and the drill pipe, the drill bit is a rotating ...
