ORGANOFUNCTIONAL COMPOUNDS FOR SHALE STABILIZATION OF THE AQUEOUS DISPERSED PHASE OF NON-AQUEOUS BASED INVERT EMULSION DRILLING SYSTEM FLUIDS

摘要

Invert emulsion drilling system fluids comprising an oleaginous continuous phase and a non-oleaginous dispersed phase, the dispersed phase comprising organofunctional compounds(s) effective to provide shale inhibition. The organofunctional compound(s) may be used either as a supplement to or as a substitute for metallic salts.
