Methods of drilling a wellbore through a production zone within a subterranean formation using a drill-in fluid that comprises an aqueous fluid and a water-based consolidating emulsion and using the drill-in fluid to drill at least a portion of a well bore into the production zone while allowing the water-based consolidating emulsion to penetrate into the walls of the well bore. The water-based consolidating emulsion itself comprises an aqueous liquid, a hardenable resin, a hardening agent component, and an emulsifying agent. |
