Zonal isolation for chemically harsh and high-temperature environments

Designed for extreme conditions, the CoilFLATE coiled tubing through-tubing inflatable packer extends critical zonal isolation capability to previously inaccessible, chemically harsh, and high-temperature environments. The CoilFLATE packer eliminates the need for a workover rig because the packer is run on either coiled tubing or jointed pipe into vertical, deviated, or horizontal tools. Remedial operations can be performed without killing the well.

Permanently abandon zones or temporarily isolate wellbore areas

The system enables permanent abandonment of zones and temporary isolation of wellbore areas for tubing integrity testing, wellhead testing, and general pressure testing applications. Its chemical resistance makes it ideal for selective placement of treating fluids required for acid stimulation, water control, and chemical treatment.

The engineered slat design allows higher differential pressures at varying inflation ratios.

The carcass restraint system ensures uniform inflation of the bladder to maximize anchoring and sealing of the element.

Robust design for severe conditions

Tapered heavy-duty slats, a high-strength carcass restraint system, a composite bladder, and a chemically resistant seal compound keep the CoilFLATE packer anchored in place, providing a high-pressure seal even at large inflation ratios (>5,000 psi at 2:1; >2,000 psi at 3:1). The CoilFLATE packer design allows extended exposure of the assembly to temperatures up to 375 degF [190 degC], under harsh wellbore conditions, and in almost any chemical environment.
