Interra Energy’s Howitzer D83® pressure testable toe sleeve is pressure-activated and used to both pressure test completion string integrity and establish communication to the formation prior to stimulation operations.

The proprietary Howitzer toe sleeve enables testing of the completion string at maximum stimulation pressure followed by the sleeve automatically opening at a lower pressure. The design enables multiple tools to be deployed in the same well to replace the first stage, saving significant time and cost.

Installation

The Howitzer toe sleeve is installed near the toe of the well as part of the casing string during the completion process. The tool can be run in a cemented or open hole completion.

Activation

After a successful pressure test of the casing, pressure is bled off, which automatically activates the tool providing assured flow area through all ports.

Stimulation

The Howitzer toe sleeve can be used to stimulate the first treatment stage of your well or can simply provide communication for all pre-stimulation operations.
