Dispersant / Thinner

As low gravity solids accumulate, it is more challenging to maintain an oil-wet, dispersed fluid system. At these extremes, a supplemental dispersant provides a thinning effect to control undesirable drilling fluid properties through stronger oil-wetting characteristics. The effects of these additives should be tested by pilot testing to minimize the risk of over-treatment.
