Downhole Desander

Downhole Sand and Gas Mitigation Tools

Premium Tools offers a product line of multiphase desander equipment for downhole sand and gas mitigation for rod pump applications. Our multiphase separator is designed to meet the harsh conditions of the downhole environment. Incorporation of our desander will help to reduce sand content in the produced fluids before reaching the pump, resulting in extended pump life. The separation methods are field proven, and each system is designed to meet or exceed applicable standards.

Design features

  • Primary (Sand) spiral to separate sand and solids
  • Secondary (Gas) spiral to assist in gas breakout and separation
  • 30' diptube allows sufficient distance for gravity separation of free gas as fluid travels through the desander
  • Stainless steel diptube offers high resistance to corrosion, ensuring long operational life of equipment
  • Lower bottom sub is offered in two options:
    – Heavy wall is machined from 4140 steel with a 3/4" wall thickness for extended erosion life
    – Light wall is machined from 4140 steel with a 5/16" wall thickness
    – Both subs utilize a machine flat along their axis to ensure the mud anchor is not severed from the bottom of the desander due to erosion at the end of their useful life
  • Screen wrapped slotted section is optional
    – Slotted section is typically screen wrapped to prevent large foreign material from entering desander and plugging pump
