Production enhancement with a capillary injection system has been one of the fastest growing forms of artificial lift & downhole chemical delivery over the past 10 years. The team member’s at Drover Energy Services have played a significant role in the growth of this industry. Our team has a combined 100 years experience in the capillary market and an excess of over 8000 installations worldwide.

The success of the customer has been the main reason for the growth of the capillary industry, attributed to the simple proven concept of a precise continuous delivery of chemical directly at the area of need! With all the experience and shared success, we pride ourselves on still being an original, fresh-thinking group. We understand the importance of listening to your needs and in return offer an innovative capillary solution, outlined with many years of experience!

Thank you for visiting our website! Don’t hesitate to call or email with a question that concerns your needs!


  • Tubing can be removed and re-installed multiple times.
  • Minimal wellhead modifications.
  • Eliminates down time.
  • Accelerates Production and Maximizes recovery.
  • Precise placement and continuous delivery of chemicals.
  • Provides multi chemical solutions or well monitoring options.
  • Proven success and variety of alloys in severe, high pressure environments.
  • Small footprint, versatile, modular equipment.

The applications listed below provide best results when applied precisely at the area of need with a capillary system compared to backside treatments. “Trickle down” treatments also have serious limitations due to the concentrations needed to effectively treat and fall down the annular space, especially when gas is present. Also a limitation if the production tubing is above the desired point of treatment.


  • Foamers for Liquid Loading Applications ( this relates to the LASSO program below)
  • Paraffin Inhibitors and Solvents.
  • Salt Deposition
  • Hydrates
  • Asphaltenes
  • Emulsion Breakers
  • Scale and Corrosion Inhibitors


Drover Energy Services well candidate selection software is backed by years of experience and 1000’s of well review and evaluations with our customers identifying liquid loading applications for capillary. The software is backed by proven equations established by the Turner’s Liquid Loading tendencies and also takes into account a foaming agent’s ability to reduce surface tension and the density of produced water.

The example below is provided for a customer’s individual well and calculates critical velocities needed to unload fluid based on input parameters provided. These calculations also provide a foamed velocity needed to keep your well bore dehydrated of fluids and increase production back to its natural decline curve. Drover’s LASSO software also takes into account the importance of understanding temperatures, chlorides and depth to select the proper alloy for each installation.

Drover’s years of hands-on experience, growth in the industry and our selection software all combine to provide a valuable tool for our customers.
