StingBlade Bit Helps Drill 12 1/4-in Section Shoe to Shoe in One Run, a First in the Rumaila Field, Iraq

The StingBlade bit in the integrated BHA successfully drilled the 1,435-m 121/4-in interval shoe to shoe in a single run at an ROP of 9.3 m/h [30.5 ft/h], 64% faster compared with the offset wells’ average in the field. After completing the interval, the StingBlade bit was pulled out of hole with a good dull condition. The system built angle from 0° to 12.5° inclination with 3°/30-m [3°/100-ft] dogleg severity, and ROO saved 3.74 days of on-bottom drilling time compared with offset wells.
