STRATAJET

MULTISTAGE SYSTEM

Features

  • Unlimited straddle frac stimulation stages.
  • Unrestricted full ID wellbore.
  • Provides limitless remediation and restimulation possibilities.
  • Wellbore above treated interval remains closed avoiding frac break-around when compared to pre-perforated laterals.
  • Pressure-activated sleeves do not require mechanical manipulation by a shifting tool.
  • Coiled tubing circulation enables ease of wellbore circulation in case of screen out.
  • Phased port configuration provides 360° reservoir access.
  • 100% flow area reduces friction during stimulation.
  • Shift sleeve travels up to prevent unintended opening with wiper plugs.

Overview

Interra Energy’s StrataJet® Multistage System uses pressure activated sleeves that are opened in conjunction with our AccuStim™ Coiled Tubing Straddle Packer, which is also used to deliver the stimulation treatment to each stage. The unique design of the StrataJet Frac Sleeve provides a full inside diameter (ID) tool capable of unlimited stages. Compared to burst port style systems, 100% flow area and 360° reservoir access is ensured upon shifting the StrataJet Frac Sleeve open. The system can be run as a cemented or open hole completion.

Operation

The StrataJet Frac Sleeves are installed as part of the casing string during the completion process. The tools are spaced within the wellbore based on client requirements to effectively target the reservoir.

Interra Energy’s AccuStim Straddle Packer is then deployed on coiled tubing (or jointed pipe) to isolate and stimulate each stage within the wellbore. With the isolation tool positioned across the first StrataJet Sleeve, hydraulic pressure applied down the coiled tubing (or jointed pipe) activates the sleeve to open, providing reservoir access.

The stimulation treatment is then pumped through the coiled tubing (or jointed pipe). The process is repeated for subsequent stages to efficiently stimulate the wellbore in a single tool deployment.
