Typical Physical Properties

Appearance: Dark amber liquid

Specific Gravity @ 20° C: 0.84 to 0.92 gr/cm3

Viscosity @ 20° C: Less than 50 Cps

Flash Point: ~ 100° F

Solubility: Oil soluble, water dispersible

Pour Point: Less than 3° C

Product Application Details


COR DPE is formulated to be used as a general purpose drilling inhibitor. The normal treatment rate of COR DPE is 0.5 to 1.0% of inhibitor based up on the volume of fluid to be inhibited.


COR DPE can be added to the drilling fluid in the mud pit, or spayed or dipped on to the drill string, when it is being run.


Dilution with equal parts of diesel are recommended, in order to make the inhibitor manageable. COR DPE will protect against carbon dioxide and hydrogen sulphide. In general the doseage rate of COR DPE , should be increased as the mud weight increases, or the drill solids in the mud increase.
