Rate of Penetration (ROP)
Definition - What does Rate of Penetration (ROP) mean?
Rate of penetration (ROP) is a measurement of the speed at which a drill bit break through rock and soil to penetrate a borehole. It is mechanically monitored using a geolograph. ROP can be expressed in either units of time or distance.
Rate of penetration is also known as penetration rate or drill rate.

Drilling operations make use of highly advanced technology. The rate of penetration measurement is a way to quantify progress. In terms of distance, ROP can be expressed as feet per hour. Distance drilled is expressed in minutes per foot.
The use of a drilling recorder, known as a geolograph, is a way to automate ROP measurement. The geolograph charts the ROP on a paper graph or electronically. Computerized measurements may be more precise than traditional methods, but accuracy depends on the surface responses to the drill bit.
