OBM-Filtration Control is a high-quality grade of natural asphalt-based agents that is widely used in oil-based mud systems to minimize filtration and forming thin filter-cake in wellbore surface in high temperatures (up to 300 Fahrenheit degrees). OBM-Filtration Control is modified Gilsonite which is excellent filtration control in temperatures above 160 °F. It is soluble in crude oil in high temperatures, and increases emulsion stability of oil-based mud in different mud densities and oil/water ratios.
Advantages
- Forming high quality filter cake on wellbore walls
- Provides excellent filtration characteristics
- Compatible with most types of regular oil-based muds
- Easy to mix
- Stable up to 300°F
- Increase emulsion stability characteristic
- Minimize filtration damage in reservoir formations
