Data Sheet

High-performance wellbore repair solution

Where higher yield or collapse strength is needed, Enventure offers the enhanced ESeal HP Patch expandable casing repair patch. This permanent and cost-effective alternative to cement squeezes and legacy remediation methods is the first choice for operators who need a permanent, inexpensive casing patch solution when facing higher differential pressures. Unlike the standard ESeal Patch, this enhanced tool utilizes high-yield strength material and incorporates five elastomer bands as top and bottom anchors. This robust design allows the ESeal HP Patch to withstand up to 48% higher internal yield and 50% higher collapse pressure ratings.

Like the ESeal Patch, this tougher, more robust solid steel expandable tool provides a quick, inexpensive, and permanent seal while reinforcing short casing sections, restoring well integrity and prolonging the life of the well.
