Challenge: Drill challenging sections with
inclinations higher than 80° in an extended-reach (ERD) exploration well
and perform an openhole sidetrack in the 6-in section after a coring run
Solution: Design a BHA that includes the
PowerDrive X6 rotary steerable system (RSS), a full suite of LWD services, a
PDC drill bit customized using the IDEAS integrated drillbit design platform,
and the MEGADRIL oil-base drilling fluid system
Results:
- Constructed the first ERD exploration
well in the Baltic Sea
- Drilled and cased the challenging trajectory while maintaining borehole stability.
- Increased ROP in all sections compared with the nearest offset ROP
