Halliburton GasVault™ float valves provide a gas tight mechanical barrier designed for a safer wet-shoe track
Talk to an expertIntentional and unintentional uncemented shoe tracks, referred to as wet-shoes, are a common occurrence when cementing the production string on unconventional wells. In these occurrences, the shoe track may no longer qualify as a reliable barrier due to a lack of cement or contaminated cement inside the casing. These scenarios create the need for a mechanical barrier at the casing shoe to prevent formation fluid or gas from entering the casing and reaching the surface. The GasVault float valve is an improved float equipment barrier that allows operators with a wet-shoe track to safely rig-down drilling equipment and efficiently move to the next pad as soon as the cement job is complete.
The GasVault float valve features decades of Halliburton float equipment design and experience and has been tested beyond API specification 10F. Gas tested to 5,500 psi and fluid tested to 15,000 psi at 300°F after enduring 48 hours of direct flow at 10 bbl/min with sand-laden water-based mud, GasVault float valves can provide a reliable barrier for a safer wet-shoe track.

Reliable by Design
The GasVault float valve is constructed from alloy steel and utilizes a flow protected spring. On highly extended horizontal production strings the 0.63-in. Critical Flow Path Dimension (CFP-D) ensures that the valve has a higher debris tolerance. The industry leading 5.93-sq.in. flow area contributes to reduced pumping pressures and jetting actions, which minimizes erosion, to further increase durability.
