Pressure test for maximum wellbore integrity and immediately initiate reservoir communication upon bleed-down.
Interra Energy’s Howitzer™ toe sleeve is pressure-activated and run on casing to the toe of the well. This tool is 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 perforated stimulation “cluster,” saving significant time and cost.
Features and Advantages
Pressure test casing to maximum required operating levels prior to stimulation
Establish communication between completion string and formation for pump down or ball-drop operations
Eliminates use of tractors, coiled tubing, perforating and other intervention methods to establish communication prior to commencing stimulation operations
Increases operational efficiency by eliminating additional days required by existing methods
Reduces operational risk and increases safety by reducing manpower required on location
Reduce overall completion costs
Meets or exceeds all North American regulatory requirements
Does not require pup joints
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.
After a successful pressure test of the casing, pressure is bled off, which automatically activates the tool providing assured flow area through all ports.
The Howitzer toe sleeve can be used to stimulate the first treatment stage of your well, or can simply provide communication for all prestimulation operations.
