Ground Control Xan
Drilling in hard conditions take good tools and a clear plan. Unlike sand and clay, the spoils or cuttings from drilling rock, gravel, and other hard material require an additive specifically developed to suspend larger spoils and cuttings within the mud mix. Ground Control® XAN is an anionic polymer designed to encapsulate and suspend and float heavier cuttings out of the borehole. As an effective viscosifier, it also reduces friction and offers increase hole stability for a smooth pullback.
Best Mix: Mix 64 oz bottle of Ground Control® XAN with 500 gallons of water / soda ash as needed to maintain pH of 9-9.5.
Alt Mix: Add a second 64 oz. bottle to mix above in heavy sand or silt conditions
