Water is life – for 150 years now H Anger’s Söhne (HAS) has made a prosperous contribution to the exploitation of the “blue gold” of our planet. Whether it be drinking water, mineral water or industrial water, HAS takes pride in looking back on a history of approximately 8000 successfully drilled wells.
Anger’s has always constructed wells for various purposes to clients’ satisfaction: from the very beginnings of percussion drilling, today still a popular drilling method, especially in the area of mineral water to the newest technologies and equipment. During this time, Anger’s could, and still can, always profit from its decades of experience and its knowledge of well construction. This enables the company to carry out drilling and completion professionally even in sensible areas.
Safety is our number one priority!
The protection of the health of employees and environmental protection are at the top of Anger’s agenda.
“Safety and protection of our employees is a major concern of ours. This is not only about the avoidance of accidents, but also about the specific advancement of health of every single employee. To do so, we have introduced safety trainings as well as an incentive scheme for accident-free working. On the other hand, environmental protection is of great concern to us, too. Being a central topic of our business policy, we not only obey current standards of environmental protection, but we exceed them.”
Martin Müller-Ruhe, general manager H. Anger’s Söhne.
Types of wells
Anger’s is able to drill wells in all different classes according to DIN 18300 VOB/ C. Depending on the soil class wells are being distinguished as follows:
Loose rock wells
Loose rock means soils that consist mainly of sand, gravel, silt or clast. These parts form Classes 1 to 5 according to DIN 18300 VOB/C. For the drilling of wells in these kinds of soil, wing bits or, if needs be, tri-cone bits are used normally. One very important aspect with these drilling technologies is a balanced mud-management programme in order to keep the borehole stable. In Germany, soils like these can be found mostly in the northern parts.
Solid rock wells
Wells in solid rock are drilled using so-called button bits. Solid rock means compact rock, like for example granites, which form Classes 6 and 7 of DIN 18300 VOB/C. H. Anger’s Söhne has a lot of experience in the drilling of solid rock wells which are mostly constructed in middle and southern Germany due to the given geology.
Depending on the geology to be expected, Anger’s carries out all current methods of drilling: the use of direct rotary flush, air-lift, dry drilling (cable drilling) or downhole hammer drilling makes it possible to adjust to the prevailing conditions – because every well building is unique in its own way. Exact planning and technically flawless realization guarantee the best implementation possible.
