Summary
OBF-LUBE ES, a mixture of various surfactants and mineral oil, plays a role in anti bit-ballling and reducing friction in the drilling fluid, ensuring the cleanness of the drilling tool when drilling.
OBF-LUBE ES can reduce the friction between the drilling tool and the well wall and mud cake, which can improve the quality of mud cake.
OBF-LUBE ES, low fluorescence, does not affect geological logging.
OBF-LUBE ES is suitable for various water-based drilling fluids prepared in fresh water and salt water.
Usage range
Temperature:≤150℃ (BHCT).
Recommend dosage：0.5~1.5 % (BWOC).
