Eliminate the use of potentially damaging fluid loss control materials

Our mechanical fluid loss prevention devices are typically used in sand control completions. Placing a valve in the production string to isolate reservoir fluids eliminates the need for spotting potentially damaging fluid loss control materials after pulling the service tool from the packer assembly. The range of valves includes

  • flapper valves 
  • bidirectional barrier valves suitable for HPHT environments, as well as for deepwater and other harsh environments where debris tends to accumulate and valve actuation requires more force.
