Performance Test :

• Preparationof of base mud : Prepare 10 - 15 cP Bentonite Suspension from pre-hydrated Bentonite Suspension prepared by stirring 10% (w/v) Bentonite in Distilled Water for 30 minutes using Laboratory stirres (5000 - 6000 rpm ) and aged for 72 hours at 90 ± 2^oC by diluting with Distilled Water and stirring in a Hamilton Beach Mixer for 20 minuts. Treat the prepared Bentonite Suspension with KCI (10% w / v) and age for 24 houre at 24 ± 2^oC After that add PHPA (0.2% w / v) +PAC (Regulaar Grade) (0.5% w / v) + PAC (Low Viscosity Grade) (0.3% w / v) +
