Systems and methods for automatic weight on bit sensor calibration and regulating buckling of a drillstring

A system for optimizing weight measurements in drilling operations, comprising:

• a bottom hole assembly coupled to a drillstring extended into a borehole;
• one or more survey probes arranged on the bottom hole assembly and configured to take a first survey recording at a first depth within the borehole, the first survey recording providing inclination and azimuth of the drillstring at the first depth;
• a sensor sub arranged on the bottom hole assembly and configured to measure a weight on the drill bit at the first depth;
• a data acquisition system communicably coupled to the one or more survey probes and the sensor sub and able to receive and process the first survey recording and the weight on the drill bit;
• and
• a weight and torque corrective model communicably coupled to the data acquisition system and having one or more processors configured to calculate a predicted borehole curvature at a second depth within the borehole, the predicted borehole curvature being at least partially based on the inclination and azimuth of the drillstring at the first depth and a predicted inclination and azimuth of the drillstring at the second depth, the one or more processors being further configured to calculate a weight correction value based on the predicted hole curvature, the weight correction value being used to calibrate the sensor sub.
