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 the first prototype of the simplest pump, pneumatic operated, which we tested in a freshwater 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 involved 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. Such a solution is very beneficial for Hansenpumps, as we need less staff ourselves to get to the commercialization stage. Mid 2017 Westco in Norway purchased shares in the company.
One can question why it has taken us such a long time to get to the commercialization stage. That is simply due to the fact that the founders had other jobs that required the majority of the time, as well as we knew we would benefit in not rushing the development of the technology. How many times have we developed technologies too fast, and after that found that the product could have benefitted in allowing more "thinking time"? ;-)
The company had up to 2016 no outside "investors" or venture capital. We believe so much in our new solutions, capabilities and the customer feedback, 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. We are planning to open up in the area of Houston, Texas, which will lead us to seek investors to grow the company to what we believe this can become.
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. Aarbakke Innovation, one of the co-owners, has significant experienced resources in mechanical design, manufacturing, assembly, testing, etc. See www.aai.no for info.
Our main manufacturing facility at Aarbakke AS is located on Bryne, Norway, and is perhaps one of the best machine shops in the world.
