Challenge:
- Drill a highly abrasive formation in Russia with PDC bits in a single run.
- Maintain cutter integrity and reduce trips.
Solution: Run StingBlade conical diamond element bits featuring Stinger conical diamond elements with a PowerPak steerable motor for increased ROP through improved impact strength and durability.
Results:
- Drilled with a PDC bit, for the first time, in one run in the Starooskolsky horizon.
- Reduced drilling requirements to two bits in two runs for the entire section.
- Increased average ROP 70% versus other drilled wells.
- Saved 9.2 days versus AFE and 1.1 days compared with the best previously drilled well.
