Gilsonite OBM FL Control agent

Product Introduction:

Gilsonite is a naturally occurring asphalt used for high-temperature, high-pressure (HPHT) filtration in all oil-based and synthetic-based muds. It is designed for applications where the bottom hole static temperature (BHST) is below 400°F. versatrol HT can extrude into formation microfractures to form a sealing/plugging mechanism, stabilizing shale and preventing sloughing. It also increases viscosity, particularly at lower temperatures, due to its partial solubility. When used in the field, monitor solids control equipment for several circulations after the initial addition to ensure the product is not being discarded.
