Description

It is a modified sodium sulphonated asphaltic compound that stabilizes shale, inhibits dispersion of drilled solids, reduces torque and drag and acts as an alternative to oil usage etc. and aids emulsification.

Application

For shale control, fluid loss control and for lubricity improvement.

COMMON NAME – SODIUM SALT OF SULPHONATED ASPHALT.

Advantages

• It is compatible with all water base mud systems.
• Improves lubricity thereby reducing torque and drag of chilling string.
• Prevents bit and down hole assembly bailing by preferentially oil wetting the drill string.
• Seals small fractures in stressed shale formulation.
• Contributes to corrosion inhibition.
