Task Group 1: Disposal/Recycling of Drilling Fluids

from Horizontal Directional Drillings


Task group 1 will deal with the issue disposal and recycling of drilling fluids in HDD. This task group shall work out approaches and possible solutions of the matter; thus it shall make sure that an amicable procedure will be on hand in future concerning the disposal or recyling of drillings fluids for all parties involved. The issue will be dealt with in close coordination with the Niedersächsische Ministerium für Umwelt, Energie und Klimaschutz (Lower-Saxon Ministry for the Environment, Energy and Climate Protection).



Technical Leadership:       


Dipl.-Geol. Björn de la Motte, de la Motte und Partner




  • Interpretation of the KrWG (Closed Cycle and Waste Management Law), the BSchV (regulation governing employment) and the DüMV (fertiliser regulation)
  • This decree does not close the door to deploy cuttings and drilling fluids onto agricultural areas!
  • Elaborating the conditions facilitating a disposal on agricultural areas.
  • Compiling all chemical key data of the drilling fluids to be able to make a statement concerning the products’ agreeability with soil (with reference to agriculture)
  • Chances to reduce the quantity of drilling fluids (which reduces the problem but is already state of the art)
