patents & trademarks
As a specialist in well development and rehabilitation, we have developed unique technologies that achieve best results on treating water wells and open boreholes. These are our protected trademarks.
The can be seen as a mobile workshop, which travels to the construction sites in order to carry out all the work that needs to be done on the well. The can be configured in the form of a truck, container, skid mounted or trailer mounted. Depending on the requirements for the work on the well and local conditions, the can be configured exactly to the respective needs.
in germany we use the truck version of the exclusively. For pump installation and removal, a crane can be installed in the truck, which is controlled by a power take-off. It can be designed for a wide range of well depths and extensions, depending on the user's requirements. Of course, the also has all the equipment for well development and well rehabilitation on board. Thus, the (scroll down to learn more about it) can be performed with the .
The intelligent solution with the roof boxes in the truck version allows space-consuming and heavy components such as risers to be transported on the roof. The boxes are placed on the construction site directly next to the well. This saves time for site preparation on the one hand and space inside the truck on the other. Tools and other important equipment such as pumps, airlift, measuring tools, TV equipment and much more can be easily carried in the .
the is also available in other configurations
for a good understanding, our patented high pressure impulse process (= ) combined with our technology are explained together.
compressed water generated by a high pressure pump is passed into the well with a hose reel.
At the end of the high-pressure hose, there is a so-called bi rotational unit which moves up and down the well during the entire rehabilitation or well development process. Above it, a submersible pump is installed which removes the loosened deposits simultaneously.
has centralizers above and below the bi-rotational unit, adjustable to the well diameter, with two pairs of eccentric nozzles arranged in two planes. the angle of the nozzles is adjustable to the geometry of the well screen material which leads to an enormous depth effectiveness in comparison to other so called "jetting"-units. only This application with adjustable nozzle angles, developed and patented by us, is called and is unique worldwide.
As soon as the water emerges at , the pairs of nozzles begin to rotate, counter-rotating by means of the recoil principle. They reach a rotational speed of approximately 7000 rpm which ensures that with up to 550 bar high pressure impulses are generated.
Instead, the water jet is transformed into an extremely fine spray and swirl whereby the energy which is stored in the water is transformed into so-called pressure impulses. These have the effect that the gravel starts to swing. The individual grains of the gravel pack swing against each other thus already solidified deposits within the gravel pack can be loosened by mechanical means.
At the same time, the deposits can then be pumped out by the submersible pump which is installed above the bi-rotational unit. this whole process is called .
In order to successfully clean or develop wells with it, an enormous amount of know-how is required. For each well, the applicable pressure, the size of the nozzles, the distance to the well screen, the travel speed of the hose winch and the rotational speed are adjustable to the material and condition of the well screen. the angle of must be individually adapted to the corresponding well screen material.
We have acquired this know-how over decades in all geological formations and have continued to develop and perfectionize the process. it is now used by partners in europe, the united states and asia.
