Weatherford International has released their IntegraLine liner system with swage technology at the International Association of Drilling Contractors (IADC) World Drilling 2015 Conference and Exhibition.
Weatherford’s IntegraLine liner system has been designed and engineered for applications in ultra deepwater, extended reach, and sour gas wells with high pressures and temperatures. The system is comprised of three components: the polished bore receptacle, liner-top packer, and rotational hanger. The packer features swage sealing technology that forms an anti-extrusion, gas-tight barrier between the outer diameter of the packer body and the inner diameter of the host casing. Alternative components are also available to create a fit-for-purpose liner-hanger solution for specific, complex applications.
In a gas and condensate well in Alberta, Canada, the IntegraLine liner system with SwageSet packer established a gas-tight seal that enabled fracturing through the liner. Stimulation pressures reached 8288 psi (57,144 MPa), and the system maintained zero pressure losses throughout the frac application.
