Gas Well Deliquification Flow Loop

C-FER designed and built the Gas Well Deliquification Flow Loop (DFL) to perform qualification and performance tests on novel gas well deliquification technologies, using water, oil, air, or a water/solids mixture as the test fluid.  Testing a system in this flow loop provides the client with a very low risk, affordable opportunity to learn how their system functions under specific test conditions prior to deployment in the field. 

The instrumentation is also easily moveable off-site to a controlled “test well” so that testing under more realistic conditions can be achieved.  C-FER currently has the majority of the necessary wellhead equipment, 4 ½” casing, and coiled tubing hangers to enable the installation of a coiled-tubing-deployed deliquification system into a 9 5/8” vertical well at the Enform facility in Nisku.


Physical Setup

  • Bottom 18 feet of casing is transparent acrylic for visualizing pump during testing
  • Can be mounted vertically or horizontally (minor modifications required for diagonal mounting)
  • Coriolis meter measures density for percent solids calculation
  • Vortex meter measures flow rate of air into the casing for determining gas injection effects
  • Captures test data at 4 points per second (or higher); ideal for cyclic (transient) pumping systems
