NOV introduces valves to Permian basin
13 March 2018
National Oilwell Varco (NOV) has introduced its Patriot fluid end and Blue Thunder valves in the Permian basin.
The Patriot advances fluid end technology to be even more applicable in high-activity areas like the Permian. The new stainless-steel fluid end exhibits peak stresses within 50% of a Y-block fluid end, realizing low-stress advantage without higher maintenance requirements, and improved geometry yields a 40% stress reduction in the bore intersection. A two-piece valve retainer allows easier assembly and gives clear “line-of-sight” confirmation for proper alignment, which typically isn’t offered with other grooveless fluid ends.
The Patriot has a 26% increase in flow area around the suction and discharge valves, which reduces cavitation and fluid-end washouts, and a discharge flange allows full access for impact and torque wrenches.
The Blue Thunder well-service valves, available fully bonded or with snap-on insert, significantly enhance service life. Rated to maximum temperature of 180°F (82°C) and maximum pressure of 20,000 psi, the valves’ forged high-strength steel unibody construction allows greater flow area and is designed to handle even extremely high amounts of solid contents, which are commonly seen in the Permian. The new valves reduce abrasion, which results in few replacements, longer run times, and reduced cost per pumping hour, and are compatible with most fracturing pump fluid ends.
