Falcon

Flow-through circulating and hydraulically actuated frac valves

The flow-through circulating valve enables circulation while the system is being run in the hole. When the liner reaches the desired position, a ball is dropped from surface and pumped down until it lands on the ball seat, permanently closing the circulation valve. Pressure can then build up to set the hydraulic packers and actuate the hydraulic frac valve, enabling communication with the first fracture zone.

Hydraulically set and swellable packers

Falcon system packer elements are engineered from a complex polymer suited for high-pressure applications to achieve sealing during stimulation as well as production. Hydraulically set packers use pressure to activate a positive-lock mechanism that expands the packer element, sealing against the formation.

ResPack swellable bonded-to-pipe packers are designed to swell on contact with fluid—water or oil. The elastomer is bonded directly onto the basepipe. An integral delay mechanism engineered into the polymer minimizes the risk of premature swelling and setting without the need for any additional exterior coating. The packer has no moving parts.

Ball-actuated frac valve

Progressively larger balls are dropped from surface to seat in and shift open the ball-actuated frac valves, establishing communication with the zones of interest. The frac valves use spherical ball-seat geometry to prevent stuck balls during fracturing and the consequent loss of production from the zones below.

Use of ELEMENTAL degradable technology frac balls eliminates the need to flow back or mill the balls after fracturing because they degrade predictably and fully at bottomhole conditions.

Liner top packer

With a full range of liner hanger assemblies and liner-top packers within the Falcon system portfolio, a fit-for-purpose solution can be provided for the deployment of stimulation systems and securing of the system in the well. The liner-top packer elements are ISO 14310 V3 qualified. The liner hanger system can be deployed via a mechanical right-hand-release running tool (RRT), hydraulic collet running tool (CRT), or latchdown tool.

Optional sealing bores of various lengths are available for liner tieback in latched or unlatched seal assembly applications.
