Interra Energy's StrataJet® multistage coil frac sleeves are pressure activated and 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 coil frac sleeve provides operators with a full inside diameter (ID) tool capable of unlimited stages. Once activated, the tool offers 360° reservoir access and 100% flow area in cemented or open hole well environments.

Installation

StrataJet multistage coil 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.

Activation

Interra Energy's AccuStim coiled tubing 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.

Stimulation

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. 

Abrasive Cutting

• High water usage

• Associated costs:

  • Product

  • Transport

  • Storage/Heating/Recovery

• Increased sand production

• Plugging of formation pore throats

Perforating

• Increased safety risk

• Formation and cementing integrity damage

• Perforating debris

• Additional runs required

• Frac communication between stages on pre-perforated laterals

• Logistically complex
