The operator contracted Weatherford to enlarge a 3,641-ft (1,110-m) hole section from 8½- to 9½-in. on an offshore development well. The company deployed a dual-reamer bottomhole assembly including a RipTide drilling reamer and a RipTide rathole killer drilling reamer.
Radio-frequency identification (RFID) tags enabled both reamers to be opened and closed remotely and selectively throughout the run, Weatherford said, allowing the crew to drill and ream the hole section to a total depth of 14,629 ft (4,459 m), eliminate the rathole, and clean the wellbore in a single trip.
According to the company, by removing the need for a dedicated cleanout trip, which takes an average of 52 hours in this field, the RFID tools produced significant value in terms of time, cost, and operational efficiency.
