These are the actual ton-miles of work involved in drilling down the length of a section of drill pipe (usually approximately 30 ft) plus picking up, connecting, and starting to drill with the next section. To determine connection or drilling ton-miles, take 3 times (ton-miles for current round trip minus ton-miles for previous round trip): Td = 3(T2 - T,) where Td = drilling or “connection” ton-miles Tz = ton-miles for one round trip-depth where drilling stopped before coming out of hole.
