Abstract
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.
Claims17
A method of drilling a wellbore through a production zone within a subterranean formation comprising:
- providing a drill-in fluid comprising a water-based consolidating emulsion;
- using the drill-in fluid comprising a water-based consolidating emulsion to drill at least a portion of a well bore into the production zone;
- and,
- allowing the water-based consolidating emulsion to penetrate into the walls of the well bore.
A method of consolidating particulates in surrounding a portion of a wellbore in a production zone within a subterranean formation comprising:
- providing a production zone within a subterranean formation comprising unconsolidated or loosely consolidated particulates;
- providing a drill-in fluid comprising an aqueous fluid and a water-based consolidating emulsion;
- using the drill-in fluid to drill at least a portion of a well bore into the production zone;
- and,
- allowing the water-based consolidating emulsion to penetrate into the walls of the wellbore and to consolidate at least a portion of the unconsolidated or loosely consolidated particulates therein.
