Post-well conformance assessment requires identifying the realized locations where an as-drilled trajectory changes between its principal inclination regimes; planned breakpoints are targets, not observations. We formulate this task as sparse event localization using domain-informed multiscale inclination features, planned-trajectory deviations, event-specific LightGBM models, …
