RELIABLE ACTIVATION AND STIMULATION OF RAPTOR OC SHIFT-FRAC-CLOSE COIL SLEEVES

Raptor™ annular frac packer Velocity™ shifting tool

Interra Energy’s Raptor OC™ (Open Close) multistage system is composed of mechanically shiftable sleeves operated with the Velocity™ shifting tool and the Raptor™ annular frac packer. The shifting tool is uniquely positioned below the annular frac packer protecting it from proppant during stimulation.

activation

The Raptor annular frac packer and Velocity shifting tool are run to the bottom of the well on coiled tubing or jointed pipe. When the bottom hole assembly (BHA) is in tension, flow is initiated down the tubing activating the shifting tool. The BHA is then pulled up through the Raptor OC sleeve auto locating, shifting open and self-releasing from the profile in one continuous movement.

stimulation

The BHA is then positioned below the sleeve, setting the annular frac packer to isolate all lower intervals. Once the frac is complete, the packer is released and positioned above the sleeve. The operator then has the option to activate the Velocity shifting tool, run down through the Raptor OC sleeve and shift the interval closed. The process is repeated for the remainder of the well until all intervals have been stimulated.

Production

After the stimulation is complete, the Velocity shifting tool can be run to the bottom of the well, activated and pulled to surface opening all the Raptor OC sleeves in one continuous motion.
