PRODUCT DETAILS

DESCRIPTION :

Oxidised Asphalt is a specially processed, air-blown asphaltic material used to improve lubricity, sealing, and high-temperature performance of drilling fluids. It provides an elastic, temperature-resistant film that enhances wellbore stability and reduces filtration in water-based and oil-based systems.

APPLICATION :

Used in oil-based and invert emulsion systems as a high-temperature fluid loss controller and sealing agent. It can also be used in special spotting fluids and squeeze treatments for sealing micro-fractures and improving stuck pipe freeing operations.

ADVANTAGES :

  • Excellent high-temperature fluid loss control.
  • Improves lubricity and reduces torque and drag.
  • Forms a flexible, resilient filter cake.
  • Enhances shale inhibition and wellbore stability.
  • Compatible with many oil-based and synthetic-based muds.
  • Can be part of spotting or sealing pill formulations.
