Challenge: Drill the landing and the lateral
of a well in soft formation on target in one run, despite high dogleg severity
(DLS) requirements, potential hole enlargement, and rapid steering response to
stay within 1 m from top of reservoir.
Solution: Use PowerDrive Archer 675 high
build rate rotary steerable system (RSS) to drill the 8 1/2-in section in one
run with a PDC bit from Smith Bits, a Schlumberger company.
Results:
- Set 8 1/2-in target depth section per plan and drilled in a single
run, saving approximately 1 trip and more than USD 400,000
- Achieved high DLS for landing and rapid steering response in
lateral
