Coiled-Tubing Conveyed ESeal™ HP Patch Restores Integrity - Prevents Redrill in Marcellus Shale

Summary:

A major Operator in the Marcellus required a solution to seal squeeze perforations which would have to withstand high pressure frac operations. The area Regulatory Agency had suspended operations, not allowing completion of the well due to poor cement behind the production casing. The Operator was required to perforate the production casing and squeeze cement. The cement squeeze alone would not hold up to the high pressures required to frac the well.
