Coil Well Service

Essential Coil Well Service ("ECWS") operates the largest coil tubing well service fleet in Canada providing coil services to producers in the Western Canadian Sedimentary Basin. With strategically and conveniently located bases, ECWS effectively provides complete services to areas such as the Horn River, Montney, Cardium, Viking, Oilsands, SAGD, Lower Shaunovan, and Bakken, furthering its commitment to its customers.

The coil tubing fleet provides completions, fracture stimulation through coil and cleanouts. While the coil tubing fleet works on both horizontal and vertical wells, they are especially proficient and the preferred equipment to complete horizontal wells. Coil tubing is continuous, with no threaded connections, and is able to work while the well is flowing and under pressure. To complement the coil tubing fleet, ECWS operates a fleet of fluid and nitrogen pumpers. Deep coil jobs often require nitrogen and /or fluid pumping to provide circulation through coil tubing to assist with conveyance through the well bore and clean outs. Nitrogen is used to lower hydrostatic pressure on formations and is also used to purge the coil to clean it out.

Leading the coil industry in safety standards, and equipment innovation, ECWS specializes in safe, efficient, and economical well interventions. ECWS' new generation of advanced coil tubing technology has enabled it to provide coil tubing rigs that are designed for rapid deployment and efficiency – with a strong focus on safety.

ECWS’ philosophy has been anchored to a genuine interest in its employees. Safety is paramount at ECWS. Thorough and ongoing training in all fields enables ECWS’ experienced employees to provide professional and unparalleled service satisfaction to all its customers. ECWS focuses on delivering safe, efficient, and competitive services.
