Solid free-flowing powdered drilling fluid additives compositions having desirable emulsifying, wetting and other performance characteristics are described. Their method of preparation and their use in oil-based drilling fluid compositions are described. The manufacturing process comprises of contacting(spraying or ...

The invention relates to powdered lubricants for water based drilling fluids. Conventional liquid lubricants containing particularly divalent ions have the tendency to grease out. The powdered lubricants have excellent dispersion properties and hence do not grease out, when added to the drilling mud in the concentra...

This invention relates to an apparatus and method for vacuum packaging drilling fluid additives and is particularly effective for low bulk density material. Vacuum sealing technology is employed to decrease the volume of the additive, thereby enabling packaging of larger quantity of additive per bag, effective util...

The invention relates to an improved invert emulsifier and the process for preparation thereof, improved invert emulsion drilling fluid compositions and their use. The oil soluble invert emulsifier is synthesized from fatty acid reaction with polyalkylene polyamines and unsaturated mono carboxylic acids. The emulsif...
