Roller cone insert Volume Indentation depth (WOB) Sliding distance per minute (RPM) .
Figure DP-7: Founder, or rock-cutting dysfunction, causes the depth of cut and ROP to be less than it should be for a given WOB, causing. .
Each of the categories of bit dysfunction will be discussed, as well as the observations that can be made to diagnose .
Bit balling occurs when drilled material accumulates on the cutting structure that begins to carry some of the applied WOB, so that the weight on the cutter tips is reduced. Con- [pdf]
