Optiflow Casing Plungers

What makes a good candidate

The best candidates are oil or gas wells with the following:

  • Enough differential pressure to lift produced fluid to surface quickly enough to keep up with the inflow of fluids.
  • For example, if the depth of the top of the perforations are at 6000' and you had 50 psi differential from bottom hole to surface line pressure, the plunger would take approximately 10 minutes to land on stop and 200 minutes to rise lifting 1 bbl of fluid. This is 3.5 hours. 24 hours per day divided by 3.5 hours is 6.9.
  • The maximum this well could lift is 6.9 bbl of fluid per day.
  • Tubing less completion is required or tubing must be removed as casing plungers need the full diameter to make a seal against casing walls.
  • Approved for production through casing with the same I.D. throughout its length, and a full open master valve at surface.
  • Liquid loading wells that require frequent swab-bing, coiled tubing clean-outs, tubing plungers or pumping units.
  • A fairly dramatic production decline curve compared to projected.
  • Wells outside these parameters may still be candidates, but must be evaluated on a case by case basis.
  • A swab, shut-in test can be a good way to deter-mine candidates. Swab a well twice in 24 hours to accurately determine fluid inflow and then shut-in for 24 hours and check pressure as often as possible to determine pressure available.
  • The more accurate the production data, the better chance of qualifying a well as a casing plunger candidate.
