Rheology duo forhigh-temperature drilling
When drilling temperatures exceed 350 °F, most rheology modifiers
fail. Cuttings and weighting agents begin to sag, resulting in poorhole cleaning. Valuable time and money are also lost.
A stable rheology system is critical for high-temperature drilling.
By combining two BYK additives, BYK offers a rheology duo thatis stable at temperatures up to 400 °F.

BYK-GO 8721

GARAMITE-7303

A liquid polymeric rheology
modifier that balances high-endrheology.

A mixed mineral organoclay for
low-end rheology that is highly
effective for hole cleaning.

Rheology duo for high-temperature drilling

Rheology duo outperforms competitor in static sag
The rheology duo significantly reduced sag, indicating theadded benefit of maintaining more homogenous drillingmud.
Together, the two additives GARAMITE-7303 andBYK-GO 8721 create stable rheology and reduce staticsag in a broad range of fluids, providing a solution to
the challenges of high-temperature drilling.
