Field notes

The described workflow carries well setup, pumps, targets, and closing inventory into each new report; correcting an earlier report is said to recalculate later records. The site also specifies a one-page legal-size PDF, daily dated backups, and a single-file way to send a well’s reporting history to another engineer.
