A modified mathematical model of an asynchronous electric drive of the rotor–a drill string–a
bit–a rock is considered and implemented, which develops and generalizes the results of …

This article proposes a novel methodology to solve an existing gap in benchmark definition
by the adoption of statistically defined benchmarks as references to test products or …

Several drilling parameters influence the rate of penetration (ROP), including formation
strength, normal compaction, bottom-hole pressure differential, flow rate, weight on bit …
