Influence of Weight-on-Bit on Percussive Drilling Performance
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. Several hypotheses have been previously proposed to explain this universal...
A Phenomenological Model of Percussive Drilling: Review of Experimental Evidence
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 existence of a sweet spot in percussive drilling, i.e., there is an optimal WOB...
Unscented Kalman filter based state and parameter estimation in percussive drilling systems
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 well bottom to efficiently transfer the impact energy to an intact rock can be...
A dynamic model of the drilling action of percussive tools
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 maximized. The reasons that have been previously proposed to explain the...
