The casingBottomDepth in WellConstruction is cross-referenced with screenTopDepth to verify that the well design has no gap or overlap between the solid casing and the screened interval. A discrepancy between casingBottomDepth and screenTopDepth can indicate a data entry error or a construction anomaly that should be investigated before the well is used for compliance sampling. Regulators reviewing well completion reports will check these two values for consistency.
