Abstract
Methods are described for drilling a wellbore through a production zone within a subterranean formation. Some of the methods use water-based consolidating emulsions that comprise an aqueous liquid and an emulsion comprising a hardening agent external phase and hardenable resin internal phase to drill along a production zone. Other methods use water-based consolidation emulsions that comprise a first emulsion comprising a hardenable resin internal phase and an aqueous external phase and a second emulsion comprising a hardening agent internal phase and an aqueous external phase to drill along a production zone.
