Case History: HydroPull™ Cleanout & Stimulation Tool
Extreme-Reach Tandem Run on Jointed Pipe in the Bakken Shale
The low pressure differential through the tool ensured the success of this extreme-reach plug millout. This job involved drilling bridge plugs in 4.5-in. (114-m) casing from 9855 to 20,499 ft (3004 to 6248 m) MD using jointed pipe with rotation. The well path was tortuous, and it was not possible to reach the bottom after 9 days of operation with a single HydroPull™ tool. A second tool was installed 3000 ft (914 m) above the first and TD was reached in 3 days.
