Reischtett geothermal drilling site - FRANCE (67)
Issue / Need
FONROCHE Géothermie drills deep geothermal boreholes that produce a large volume of drilling mud (free from cuttings).
In order to improve its environmental footprint, Fonroche Géothermie decided to implement a solid waste disposal solution as opposed to the liquid mud currently produced by its drilling operations.
This drilling mud has complex physical properties: high density, high pH, high dry matter content and very low settleability.
The implemented solution involved:
- Breaking down the mixture by adding ferric chloride,
- Flocculating the contents before being transferred to the Geotube for dewatering.
