Abstract:
Wellbore fluids and methods of drilling with the wellbore fluids are provided. One wellbore fluid may include an oleaginous continuous phase, a non-oleaginous discontinuous phase, and a polymer having a polycyclic backbone. One method may include pumping the wellbore fluid into a wellbore through an earthen formation.
