Improved invert emulsifier for use in invert emulsion drilling fluids |
| abstract |
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 emulsifier is further modified with multivalent alkali metal salts. The emulsifier stabilizes the invert emulsion drilling fluid at temperatures exceeding 400F and imparts improve d fluid properties. |
