A dynamic model of the drilling action of percussive tools
Song, Xianfeng; Kane, Pascal-Alexandre; Aamo, Ole Morten; Detournay, Emmanuel (Chapter, 2019)A phenomenological model is proposed to explain the existence of sweet spot in the relationship between the rate of penetration (ROP) and the weight-on-bit (WOB), i.e., the existence of an optimal WOB for which the ROP is ... -
A Phenomenological Model of Percussive Drilling: Review of Experimental Evidence
Song, Xianfeng; Aamo, Ole Morten; Kane, Pascal-Alexandre; Detournay, Emmanuel (Chapter, 2019)In this paper, we review and analyze published experimental findings in light of the hypothesis that the dependence of bit-rock interface (BRI) pseudo-stiffness on the weight-on-bit (WOB) is the key factor behind the ... -
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. ...
