Influence of Weight-on-Bit on Percussive Drilling Performance
Song, Xianfeng; Aamo, Ole Morten; Kane, Pascal-Alexandre; Detournay, Emmanuel (Peer reviewed; Journal article, 2020)A phenomenological model for percussive drilling systems is proposed in this paper to explain the experimentally demonstrated existence of an optimal weight-on-bit (WOB), for which the rate of penetration (ROP) is maximized. ... -
Unscented Kalman Filter Based State and Parameter Estimation in Percussive Drilling Systems
Song, Xianfeng; Kane, Pascal-Alexandre; Abooshahab, Mohammad Ali (Chinese Control Conference (CCC);1934-1768, Chapter; Peer reviewed, 2019)Down-The-Hole (DTH) percussion tool is recognized for its high average rate of penetration (ROP), when drilling medium hard to very hard rock formations. This ROP which depends on the bit-rock contact conditions at the ...
