Extended-Reach Bridge Plug Milling in the Eagle Ford Shale

April 17, 2013 | by Admin

TD was reached at 4080 ft (1244 m) horizontal, representing an extended horizontal reach of 70%. This job involved milling 15 bridge plugs from 5-in. (127-mm) casing in a horizontal well with TVD of 14,430 ft (4400 m) and MD of 18,510 ft (5640 m). The bottom hole temperature was 325°F (163°C). The first 9 plugs were milled without a HydroPull® tool, but progress stopped at 16,820 ft (5127 m) MD because of friction lockup of the 1.75-in. (44-mm) coil. A 2.88-in. (73-mm) HydroPull® tool was rigged up and operated at 1.5 to 1.75 bpm (238 to 278 lpm) above a motor and mill to remove the last 6 plugs. The plug-to-plug milling and tripping times in the last 6 plugs were the same as in the first 9 plugs.
