EFFICIENT RECOVERY OF PARTED TUBULARS IN HIGH-TEMPERATURE SAGD ENVIRONMENTS
Interra Energy’s Thermal Overshot is optimized for the high temperature environment of steam assisted gravity drainage (SAGD). After the recovery of a parted tubular, this tool enables the operator to efficiently re-enter the wellbore and latch onto the remaining injection string.

The Thermal Overshot tool is run in hole and latched onto the existing steam injection string. An internal ratcheting mechanism is actuated by pulling on the bottom hole assembly (BHA). Through a proprietary slip mechanism, the tool creates a permanent thermal seal around the existing casing, resulting in a continuous flow of steam from surface to the toe of the well.
The Thermal Overshot tool is designed to function without tension or compression, which enables it to maintain a thermal seal for the life of the well. The system is typically run in conjunction with Thermal Expansion joints to ensure proper spacing out during installation.
