Oil-based mud additives (OBM)

CLOTONEX® filtration control agent is a modified lignitic product used for filtration control in invert emulsion drilling fluid systems (organophillic lignite). CLOTONEX®  filtration control agent can effectively control and reduce HTHP Filtrate at temperatures up to 200°C. Can be used independently or in conjunction with asphalt-based STABILITE® OBM fluid loss control agent.

ADVANTA® is a cost-effective oil-based drilling fluid HTHP fluid loss control additive (can be used in diesel oil, mineral oil, crude, synthetics). It is a white free-flowing polymeric powder. Can be easily added to the mud through the conventional hopper and dissolves rapidly. ADVANTA® is recommended to use in the reservoir drilling fluids as it does not plugs the pores and does not affect reservoir filtration properties.

LIQUITROL® OBM filtration control agent is a liquid polymeric product composed of 50% active component in a solvent that is compatible with the conventional OBM systems. LIQUITROL® can be blended easily through a mud hopper or can be added directly into the active system. It is a polymer suspension, may provide secondary viscosity to the mud system.

Gilsonite/Asphaltite filtration control additive. Due to the broad PSD it plugs the microfractures to form a sealing membrane which helps stabilize shales and prevent sloughing. STABILITE®OBM filtration control additive is used in invert emulsion oil-based drilling fluids systems to control and reduce mud filtrate and create a tough, slick filter cake. STABILITE®OBM can also effectively stabilize brittle shales and reduce washouts in interbedded sand sequences.
