A bit-pull recommendation compares two uncertain paths to TD. Combine persistent degradation evidence with trip time, remaining footage, replacement performance, and risk.
Read article →Formation changes confound ROP, MSE, torque, and directional comparisons. Detect transitions, rebaseline locally, and use formation-matched evidence without over-attribution.
Read article →WOB-RPM response is nonlinear, local, and constrained. Prefer a well-supported operating region over a precise optimum inferred from sparse or mixed-context data.
Read article →MSE relates mechanical input to rock removal, but high MSE does not identify a unique cause. Diagnose departures with formation, state, dynamics, and supporting channels.
Read article →High ROP is an outcome, not a complete diagnosis. Judge it with MSE, drilling dynamics, bit condition, hole cleaning, wellbore quality, and repeatability.
Read article →Invisible lost time is the repeatable gap between actual and achievable routine work. Segment events, use defensible benchmarks, and rank total opportunity.
Read article →A useful offset benchmark matches the engineering question, coordinate, formation, rig state, BHA, bit, measurement basis, and current-well evidence.
