Hansen Downhole Pump Solutions

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

Our low complexity downhole pumps
  • Oil/water production
  • Gas well dewatering
  • Coal bed methane/Coal seam gas (CBM/CSG) dewatering
  • Kick-starting wells after workover
  • Offshore riser installations

  • Rig-less installations
  • Umbilical deployed and operated
  • Through tubing deployed
  • Jointed/spooled tubing operated
  • Designed down to 1-1/2" diameter
  • Jointed/spooled tubing operated
  • Works very well horizontally

The "Kaffiholen" closed loop downhole hydraulic operated pump - A great alternative for those wells where you want rod pumps, but crooked wells, high wellbore deviation and/or surface pollution using rods inspires you to think about alternative pump installation and operation

We develop perhaps the industries lowest complexity deep wellbore type pumping solutions, where key factors are reliability and cost to install, operate and retrieve. Our main focus is rig less deployments, where local crew (your own or from one of our many partners world wide) perform the installations, commissioning and later retrieval of the systems. That saves you cost and simplifies logistics.

Also we base our pumps on abilities for local manufacture of long components, due to the simplicity of the design and lowering transport costs. Again, saving you cost and simplifying logistics.

Using static wellbore umbilical powering the downhole pump, leakage of gas and/or oil to the environment shall be eliminated.

We have developed a larger OD low complexity hydraulic operated downhole pump (5,9" max OD) that can be used for oil or gas wells. See video below.

This pump can be jointed or spooled tubing deployed, and/or later wireline replaceable. It will work horizontal, and will be a great tool to improve total drainage from mature horizontal wells.

Retrofit downhole pump to boost production from depleted gas lifted offshore wells

The compressed gas operated pump we first developed, the DayaPump, can be used to boost production from depleted or inefficiently produced gas lifted wells, where the gas lift gas is used to power the pump. Hence, our pump may be retrofitted into the wells, to depths below the lowermost gas lift valve, where the pump will deliver fluid up to the gas lift valve(s).

This patent pending solution was invented for declined fields, where gas lift valve depth no longer are optimum for the wells to produce to its maximum potential. 

Mid 2022 we entered into a collaboration with an offshore operator in Norway, where we are now developing the pump and the associated hardware to install this into 5-1/2"  completed subsea wells. In-house testing is planned for September-October 2022.

Get power and signal down to/from the reservoir section - The Downhole Wet Mateable, Flow-through, Electric Coupler

We have developed and thoroughly in-house tested our downhole conductive electric coupler (see photo above, at left), where we have now provided the first 4 sets for deepwater subsea wells, where the coupler will enable power and signals to be transferred between the lower and upper completion string in two-stage completions.

By this technology, we have regained the opportunity to do “smart” (also referred to as instrumented or "intelligent completions") wells based on two-trip completion systems, by the downhole electric flow-through wet mateable coupler we are delivering now.

There are several key functions and actions that a wet mate need to do, to provide decades of reliable operation, where one of these are that the wellbore fluids needs to be removed in the area where the electric connections are done. It is not enough just to isolate using elastomer seals, and breaking the conductive path of the wellbore fluid by one or several elastomeric seals. We replace the wellbore fluid with a preservative fluid when connecting downhole.
