  • Drilling- Wellhead components such as Casing Heads, Casing Hangers, Tubing Heads, and Tubing   Hangers. This equipment is designed to hang off each string of casing/tubing at surface, isolate wellbore and/or backside annulus pressure for complete well control during drilling operations.
  • Completion- Stacked Gate Valves (aka Frac and Big Bore Valves) are used together to form a Frac Stack, which is used as a conduit and well control from the frac pumps through the wellhead and to the produced zones during Frac and Flowback operations.
  • Production- Stacked Gate Valves are assembled together to form a Production Tree (aka a Christmas Tree & Flow Tree)   provide a conduit for produced fluids and/or gas. These Tree’s are connected to the top of the Tubing Head and allow the produced fluids and/or gas to flow out of the wellbore through the flow line and sent to a storage facility, production facility, or in some instances a sales line. The equipment is also used for Salt Water Disposal and injection wells.
