Top-of-cement determination method
rrc.completion_top_cement_determination
How the operator established where the cement top is. This is the difference between a measured figure and an arithmetic one. The pipeline that loads this data resolves the code on the way in, so the warehouse column holds the text below rather than the raw RRC code. Both are recorded here so the original filing can be read either way.
