Time Breakdown by Section
How this works
Drilling time: (To - From) / ROP / 24 hours per day.
Connection time: Number of stands x connection time. Assumes 90 ft per stand.
Trip time: Added per section for bit trips, logging, casing.
Total days: Sum of drilling + connection + trip + mob/demob, multiplied by (1 + contingency%).
