Addrill Pa

ADDRILL PA is a high molecular weight partially hydrolyzed polyacrylamide / polyacrylate (PHPA) containing co-polymer in powder form. The product is used as viscosifier and borehole stabilizer.
Application

ADDRILL PA should be added in fresh water to get a highly viscous drilling fluid. funnel viscosity for clay or shale formation should be a Y 50 seconds per quart and a Y 60 seconds per quart for sandstone or unconsolidated sand.

Properties

Chemical Composition :Copolymer
Appearance :Granular powder
Ionic :Anionic
Bulk Density:a 1.0
pH (0.5% soln. in distt. water):7.5 A 1.0
Solubility:Soluble in water. Limited by viscosity.

Characteristics and benefits

1.ADDRILL PA is a cost effective drilling fluid applicable to all types of drilling applications like water wells, diamond coring mineral exploration etc.
2.Stabilize water sensitive formations.
3.Reduces drill pipe torque and pumping pressure.
4.Mixes conveniently with stirring in water.
5.Fluid preparation time reduced drastically as the product develops viscosity rapidly and
once prepared the fluid is ready for use.
3. High viscosity of this drilling fluid helps in better removal of cuttings from borehole.
6.Reduced recirculation of cutting back into the bore hole because of immediate settling in the pit.
7.Better shell stabilization prevents water loss through cracks and fissures
