Casing 5 1⁄2” 20 lb
KOP 8,400 ft. TVD; PBTD 19,331 ft. MD 2-5⁄8” Coil Tubing
66 Composite Plugs

This record job with a major Permian Basin operator involved milling out a total of 66 composite bridge plugs from a 10,000 ft. lateral in a 19,331 ft. MD horizontal well. The liner was 5-1⁄2” and the job was run on 2-5⁄8” CT. The 3-1⁄8” BHA consisted of a motor head assembly, hydraulic disconnect, screen sub, 3-1⁄8” High Flow-High Impact Tempress HydroPull™, 3-1⁄8” Oil States Energy Services motor and a 4-5⁄8” tri-cone rock bit. Water with friction reducer was pumped at 3.5 bpm increasing to nearly 4.0 bpm towards the end of the lateral. The wellhead pressure ranged from 1300 to 2650 psi and the pump pressure ranged from 3400 to 5700 psi. All 66 plugs were milled without incident and gel sweeps and short trips were utilized to ensure a good cleanout of well debris. This job was completed in a single HydroPull™ run with an average plug milling time of 9 minutes per plug.
