Asphasol is sulphonated asphalt addditive for water base drilling
The Asphasol is trade mark of sulphonated asphalt products in shale control and use to inhibit the swelling and caving of shales cause by hydrous disintegration.Our asphasol is Sulphonated asphalt is lost circulation additives and use to plug a zone into which the drilling fluid is being lost, to prevent a complete loss of the frilling fluid is being lost, to prevent loss of the drilling fluid into the formation being drilled, and hence as lost of drilling fluid circulation from the bottom of the drill hole to the top.
Our sulphonated asphalt agents use to plug such a zone include inorganic chemical grouts or cements containing mixtures of silicates, metallic oxides, and limestone.Our drilling fluid is HTHP sodium sulfonated asphalt is very good shale control additives in water base mud.
Usage of sodium sulfonated asphalt
Generally sulphonated asphalt is blend of Gilsonite, blown asphalt, lignite, caustic soda and mixture of latter compounds.
Sulphonated asphalt using because of foaming in water and it is partially soluble in water and fully emulsion in the fluids.Liquid additives is develop to overcome some of the problems associate with the use of dry additives. However, liquid compositions containing polyglycols can give rise of stability problem.
How to use sulfonated asphalt.
Aasphasol fully emulsion in water while gilsonite will remain on top.
In particular first the viscosifier is mix with mater and then the polyglycols and finally the sulfonated asphalt.
