Automated Control of Drilling Process to Improve Efficiency of Oil Well Construction
Bit efficiency is determined by several factors; penetration per bit, rate of penetration, drilling speed per run, and operating costs per meter of penetration. Optimal drilling conditions usually meet the criterion of a minimum cost per 1 m drilled, which is defined as the minimum amount of energy required for …

How Tool Joint Build-Up And Extension Affects the Structure and Physical Properties of the Tool Joint and Drill Pipe Body Friction Weld Zone
The construction of oil and gas wells produces considerable wear and tear on the outer surface of drill pipes, especially those operating in horizontal sections, therefore various tool joint build up techniques have been used for both the repair of the outer diameter and to extend the tool joint. During …
