Product Name: BENTOIL 700

Product Information: BENTOIL 700 Organophilic Bentonite


BENTOIL 700 organophilic bentonite is a viscosifier and gelling agent that can be used in all oil based drilling fluids, and is especially effective in synthetic oils. BENTOIL 700 is an amine treated Wyoming bentonite designed to yield optimal performance in synthetic and mineral based drilling fluids to increase carrying capacity and suspension properties, providing cost effective removal of cuttings.


BENTOIL 700 was developed as a viscosifier and gelling agent for use in synthetic oil based drilling fluids.

BENTOIL 700 can be used in low concentrations in diesel oil based drilling fluids. BENTOIL 700 is stable at temperatures up to 350 F.


Quickly develops viscosity at low shear and low temperature to improve cuttings carrying capacity.

• Provides approximately twice the yield point compared to other organophilic bentonites in synthetic oil based drilling systems.

• Improves hole cleaning because of high cuttings capacity

• Aids in filter cake formation resulting in improved filtration control

• Unique energy intensive batch processing of BENTOIL 700 ensures consistent product quality and cost effective performance.
