ABSTRACT:
Aqueous well-drilling fluids treated with additives comprising a non-Newtonian colloidal disperse system containing metal-containing particles, a dispersing medium and an organic compound having both a hydrophobic and a polar substituent in combination with at least one emulsifier are disclosed. Specific examples of the disperse system comprise calcium carbonate particles predispersed in a mineral oil dispersing medium in the presence of a calcium petrosulfonate; useful emulsifiers include alkylene oxide/fatty amine condensates. Well-drilling fluids containing such additives reduce the torque requirements in rotary drilling operations.
