Case Study: Gulf of Mexico Deepwater Drilling Company achieves one-trip hole enlargement and eliminates downhole trips with SLB Rhino XC reamer

Rhino XC Reamer Enlarges Deepwater GOM Well in One Trip and 62 Hours

SLB worked with Gulf of Mexico Deepwater Drilling Company on a deepwater Gulf of Mexico well where pore pressure deviations, high mud weights, and equivalent circulating density made hole enlargement while drilling a challenge. The operator also needed an extended rathole for later coring BHA stabilization, all while trying to minimize costly extra trips.

SLB used the Rhino XC on-demand hydraulically activated reamer, along with related drilling services, to enlarge the 12 1/4-in section to 13 1/2 in and then deactivate the cutter blocks to drill additional 12 1/4-in hole for the coring section. The approach eliminated an extra trip, enlarged 1,551 ft in 49 hours at flow rates up to 950 galUS/min, provided a 538-ft rathole, and completed the 2,188-ft interval in 62.5 hours.
