 GLO ASP 1000


It is a modified sodium sulphonated asphaltic compound. Its versatile mud conditioner contributes to the stability of drilling fluids, stabilizes shale, inhibits dispersion of drilled solids, reduces torque and drag, controls high temperature water loss and acts as an alternative to oil usage etc. and aids emulsification of oil.


For shale control, fluid loss improving, Torque and Drag Reduction ,Inhibition of Swelling clays  of all water mud’s.

COMMON NAME – Sulphonated Asphalt/ Shale Stabilizer /HTHP Fluid Loss Controller



  • It compatible with all water based mud systems.
  • Improves lubricity thereby reducing torque and drag of the drilling string.
  • Seals small fractures in stressed shale formulation.
  • Prevents bit and down hole assembly bailing by preferentially oil wetting the drill string.
  • Reduces the down hole with temperature fluid loss and contributes to corrosion inhibition.
  • Controls high temperature water loss.
  • Inhibits swelling  clay and water wetting of shale’s
  • Reduces HTHP(High Temperature High Pressure) Fluid Loss
  • Improves Filter cake Quality and helps seal micro fractures
