STABILITE®OBM (gilsonite - asphaltite/OBM fluid loss control)

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.

STABILITE®OBM is an OBM fluid loss control agent based on naturally occurring asphalt.

Description

STABILITE®OBM filtration control additive is a high melting point asphalt 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.
