Case Study
9-⅝” TURBOCASER REAMS 707 FT IN 33 HOURS
The Background
- An ERD well located o shore in Abu Dhabi with 10,000 ft 12¼” hole section
- Setting casing deeper was required to eliminate the need for an intermediate liner
- Challenging environment with soft, unstable formations and high inclination
- Well sidetracked on four occasions, one lost BHA and many stuck pipe-events
The Result
- Drilling reached target depth on fourth sidetrack with great difficulty
- 10,000 ft of 9⅝” casing was run into tis extremely challenging hole
- 9⅝” TurboCaser deployed to enhance chances of successfully landing at target depth first time.
- The tool operated through many tight spots for a total of 700 ft casing and landed at target depth first time in 33 hours, a 98% reduction in time, saving the operator $13,700,000
- Successful cementing and drill out with a tri-cone bit was achieved in 1.5 hrs
