Reserves Recovered in a "Live" Well with ESeal HP Patch

Summary:

This casing failure occurred during the 13th stage of the well’s plug-&- perf frac job of it’s 4,500 ft lateral section.  To avoid killing the well with potentially damaging weighted fluids, a rig assist snubbing unit was used to enable live-well operations including milling out the casing part area, running and expanding the single-joint liner (to cover and seal the parted section), drilling out the liner ball seat, and pressure testing the installed liner.
