The screenDiameter stored in WellConstruction affects how field staff purge and sample the well. A narrower screenDiameter means a smaller well volume, which reduces the number of casing volumes to purge before collecting a representative sample. This value is also referenced when selecting submersible pumps or bailers that must fit inside the casing. Well completion reports submitted to regulators typically include screen diameter alongside screenTopDepth and screenBottomDepth.
