Claim 0:
1. A computer-implemented method of controlling a drilling operation, comprising:
determining a difference between a differential pressure and a target differential pressure,
wherein the target differential pressure is less than a differential pressure limit; and
adjusting a weight on bit setpoint as a function of the difference between the differential pressure and the target differential pressure so as to adjust the differential pressure and thereby reduce the difference between the differential pressure and the target differential pressure,, wherein adjusting the weight on bit setpoint comprises:
determining a relationship between a weight on bit and the differential pressure; and
adjusting the weight on bit setpoint based on the relationship,, wherein determining the relationship comprises:
obtaining a dataset comprising weight on bit measurements as a function of differential pressure measurements; and
performing statistical analysis on the dataset, and, wherein adjusting the weight on bit setpoint based on the relationship comprises:
determining a target weight on bit based on the relationship;
determining an adjustment to be made to the weight on bit setpoint based on the target weight on bit; and
adjusting the weight on bit setpoint based on the determined adjustment.
