Operators face many challenges with well construction designs in achieving satisfactory zonal isolation during the cementing process. Challenges with high-pressure formations requiring heavy mud weights, long horizontal legs utilizing Casing Flotation Tools, and setting the well up for later frac stimulation treatments during the casing running process utilizing Frac Sleeves and Wet Shoe Cementing processes.

Most of these conditions require a need for High-Performance Float Valve Equipment that exceeds standard flow and back pressure ratings of standard Composite Float Valves.

Davis-Lynch has the solution for these needs with our 15K Back Pressure Rated 500H Float Shoe and 700H Float Collar.
