Probabilistic Reasoning for Drilling Dysfunction Detection
Drilling dysfunctions have overlapping surface signatures. Probabilistic reasoning preserves competing hypotheses, missing evidence, diagnostic separation, and scope.

Drilling Surveillance & Reliability
Interpreting PDC Bit Wear from Surface Drilling Data
Surface data can indicate changing PDC cutting efficiency, not measure cutter damage directly. Use bit RPM, DOC, WOB, local baselines, context, and dull evidence.

Hole condition reflects accumulated cuttings generation, circulation, static time, rotation, pipe movement, and tight-hole evidence over hours, not one current sample.

Washouts and pump degradation can both reduce standpipe pressure. Flow-out behavior, hydraulic residuals, rig state, and missing evidence help separate them.
