Case Study The production section has to be drilled from 7000 ft to 10000 ft. In order to reduce the well, the production liner (47 lb/ft) need to be run. The drill pipes with weight of 23 lb/ft (9400 ft length) and Drill collar with weight of 80 lb/ft are recommended to drill the production section. Assuming that 12 lines run between the crown and traveling blocks and neglecting buoyancy effects, estimate the equivalent mast load due to leg loading as given in the figure.
