Ton mile calculation
Round-trip ton-mile
Mud weight
Measured depth
Drillpipe weight
Drill collar weight
Drill collar length
HWDP weight
HWDP length
BHA weight in air
Length of BHA
Block weight
Average length of one stand
Buoyancy factor
Buoyed weight of drill pipe
lb/ft
Buoyed weight of BHA (drill collar + heavy weight drill pipe + BHA) in mud minus the buoyed weight of the same length of drill pipe
lb
