Abstract:
A method for managing a drilling operation includes generating, by a first sensor and a second sensor of a bottom hole assembly (BHA), a first time based data log and a second time based data log representing a borehole parameter along a drilling trajectory. A time shift is determined by comparing the first time based data log and the second time based data log. The time shift is processed along with an axial distance between the sensors to compute a rate of penetration.
