Industry Article CT Annular Fracturing: ‘What’s Trending Now?’
Another positive step forward is made in the use of CT for annular fracturing.
For use in pinpoint or coiled tubing (CT) fracturing, the compact FracGUARD isolation head protects the CT string while abrasive and corrosive fracturing fluid enters at high pressures and velocities from the pump trucks into the frac tree and production casing annulus.
The frac head is engineered to provide an industry-leading flow area between its ID and the OD of the CT isolation sleeve.
CT fracturing can also be used in refracturing operations; in the event of anomalies inside the production casing, the CT can be used to push and pull equipment.
