Hansen Downhole Pump Solutions

Innovative downhole pumping solutions for deep oil wells, gas well dewatering, and more

After inventing and developing a number of complex technologies, as for example downhole permanent sensor solutions, semi stiff and spoolable carbon rod wellbore intervention system for logging long reach horizontal wellbores, permanent magnet based downhole pumps, and more, we found that a number of clients wanted a lower cost alternative to rod based pumping systems. Typically we heard that it should be rig less, it should be able to be deployed through existing gas wells down to 2-3/8" tubing, it should be simple, it should be low cost, it should be reliable and it should remove the visual pollution that the rod based systems have.

From early 2010 we then spent a considerable amount of time outlining new solutions that could meet these requests, which resulted in 4 different pump types being patented; Electrical, pneumatic and hydraulic operated.

In the summer of 2011 we built a prototype of the simplest pump, pneumatic operated, which we tested in a fresh water tank, followed by shallow depth testing in a sand and silt contaminated test well. This just to demonstrate the simplicity and functionality of the technology, where we proved that a pump can be made much simpler than what is in the market today.

2012 involves more detailed design, improvements to increase efficiency, manufacture, assembly, in-house testing, etc., of this pneumatic pump, the "Dayapump". In October 2013 we performed sea testing at 400 meters water depth, to check spreadsheet with respect to pneumatic performance and efficiency, as well as performance test a built in dump valve option that will significantly increase daily lift rates.

In 2014 we invented a wireline replaceable hydraulic downhole pump that can be used for oil wells as well as gas well deliquification. This will also function in horizontal wellbore sections.

Early 2016 we received an investment from Aarbakke Innovation in Norway, where we thereafter increased engineering resources, started a comprehensive testing program, etc.


The company has up to 2016 no outside "investors" or venture capital. We believe so much in our new solutions, capabilities and the customer feeback, that we have been using our own savings. Hence, we believe also that you the client will get better solutions; To succeed, we must be better, smarter, dedicated and giving our customers first priority. Now we are to open up in Houston, Texas, which leads us to seek investors to grow the company to what we believe this can become.


The management team is:

  • Cynthia Beckman Conroy - Sales and marketing, having long experience in technical sales and customer supports.
  • Henning Hansen - Inventor and serial entrepreneur, having a significant experience in technology development and commercialization. (Example)
  • Jamie Lindsay - Mechanical design engineer, with years of background from design of complex wellbore pumps, well intervention and completion tools, etc.


Hansen Downhole Pump Solutions AS in Stavanger, Norway, will hold the fully owned subsidiary Hansen Downhole Pump Solutions LLC in the Houston (Conroe) area.


In addition, we are using resources from a world-wide network of technology partners, competencies partners, manufacturing partners, etc., that we have built up through the many years we have worked in the industry.

Our main manufacturing facility is located on Bryne, Norway, and is perhaps one of the best machine shops in the world.
