Engineered for durability downhole, the SPRINT Packerless Gas Separator excels where others can’t— delivering efficiency for downhole separators without using a pack-off element.

By creating abrupt changes in annular tolerances, the SPRINT Separator creates pressure drops which break out entrained solution gases. This greatly reduces the free gas entry into the rod pump assembly. A ‘Pipe-in-Pipe’ design is simple but effective at separating gas upwards in the casing annulus while dropping solids downward into scalable-length mud-anchor joints placed below the separator.

Gussets placed 120° apart on the upper and lower sections of the concentric dip tube provide centralization and increase rigidity for the tool. Additionally, the dip tube sizing increases with tool size to handle greater fluid capacity in higher-volume wells. The 30-foot overall length provides an extended zone for separating gas and solids from the fluid production stream. For harsh wellbores, an optional electroless nickel or Teflon plating offers corrosion protection to extend tool life and reduce interventions.

APPLICATIONS

  • Pumps affected by gas interference and poor efficiency
  • High GOR Wells

BENEFITS

  • Improved pump efficiency boosts production
  • Increased MTBF due to decreased rod lift system wear
  • Reduced costly well intervention
  • Increased tensile strength facilitates smooth entry into challenging wellbores
  • Optimized for standard fishing techniques
  • Larger flow capacity by design, as separator OD increases, the dip tube ID increases.
  • Reduced gas interference as both free and entrained gas is separated from production fluid

Features

  • Includes a mud anchor to separate solids
  • Support gussets for rigidity and support
  • Optional EN or Teflon coating for corrosion protection
  • Threadless single piece design

Operation

  1. High velocity – Tight clearance forces increase velocity and increases presure.
  2. Pressure drop – Once fluid enters this large area a drop in pressure and velocity is seen and gas breaks out of solution and migrates up the casing, while the liquids and solids fall back into the separator top entry intake.
  3. Solids Separating – Once the fluid and solids enter this second separation area, they slow dramatically allowing for solids to sink pass the solids weir due to gravity.
  4. Mud Joints – Solids drop into the mud joints below which are connected by a threaded coupling.
  5. Dip Tube/Pump Intake – Liquid production enters the dip tube and is directed to the pump intake.
