EDC Drilling Fluids


EDC Drilling Fluids EDC 95-11, EDC 99-DW, EDC Diamond, EDC 170 SE and EDC 200 SE

Products in the EDC Drilling Fluids line are manufactured and marketed by The Special Fluids Division of Total. Their ultra-low aromatic content is significantly less than that of other available products. EDC stands for Environmental Drilling Compound. These fluids are used to formulate drilling muds used to lubricate and cool the drill bit, bring cuttings back to the surface and stabilize well walls during drilling operations.

THE Total Ecosolutions Dvantage

Our EDC drilling fluids were compared to other available reference products intended for the same use, mainly diesel cuts and clean oil drilling fluids. Clean oils have lower aromatic content and toxicity markers* than diesel cuts, but still higher than EDC products. The comparison showed that the ultra-low aromatic content and the low level of toxicity markers of EDC drilling fluids significantly reduces ecosystem and health impacts. * Benzene, Toluene, Ethylbenzene, Xylene, BTEX and BaP eq.

THE Environmental Performance

Ecotoxicological risks reduced by:

  • 18,000 compared to diesel cuts
  • 100 compared to clean oils.

Toxicity markers concentration decrease by:

  • 46,000 compared to diesel cuts
  • 54 compared to clean oils

Ecotoxicological and toxicological assessments were performed, for the first one comparing the environmental impacts related both to aromatic content and the type of aromatic compound found and for the latter by evaluating the level of toxicity markers measured in the three types of products: EDC, diesel cuts and clean oils.
