Field notes
Well profiles can be set up with a string, BHA, hole sections, and surveys, and the page says those details are saved across phone and computer. Separate account features include job-time breakdowns, timestamped notes and photos, and records for pulled bits. The sample well displays a 21-day BOP test interval, with warning colors shown at seven and three days.
