Wireline coring plays an essential role in the exact exploration of mineral deposits. This method makes it possible to examine geological layers precisely. However, in case one encounters water-bearing, loose formation layers, the most secure way of drilling is to perform a freeze hole. It should not be left unmentioned that in case accidents happen in which humans come to harm due to human error or forces of nature, it is necessary to provide help with special care and know-how: here, drilling is employed for the supply and rescue of trapped people.
H. Anger’s Söhne can look back on many years of experience in the planning and successful completion of various projects in this area. Wireline coring is used for a detailed exploration of reservoirs in order to obtain exact information about surrounding geological layers. In this, highest qualitative standards are fulfilled. The international standard is a core diameter of 100 mm. Our company, however, is capable of performing drilling with cores of different dimensions as well.
Wireline coring is furthermore used when:
- Volatile material and material under pressure must be brought to the surface as part of the core
- Preventer and overpressure technologies are employed in addition to the wireline coring
