Emulsifiers for invert emulsion drilling fluids |
abstract |
The present disclosure relates to the creation of emulsifiers for use in an oil-based drilling mud. The disclosed emulsifiers may be created by the reaction of synthetic linear saturated fatty acids and polyamines under the conditions specified. The synthesized product may be used as a replacement for the wetting agent in conventional muds. Further improvements in conventional drilling muds are also disclosed where the synthesized product is used to replace incumbent wetting agents and the primary emulsifiers are replaced by synthetic fatty acids. |
