Abstract
Nanoemulsions, miniemulsions, microemulsion systems with excess oil or water or both (Winsor III) or single phase microemulsions (Winsor IV) may be pre-formed and used as one or more fluid pills during hydrocarbon recovery operations after drilling with OBM or SBM. The nanoemulsions, miniemulsions, microemulsion systems with excess oil or water or both or single phase microemulsions remove oil and solids from the well and wellbore surfaces. In one non-limiting embodiment, a single phase microemulsion (SPME) or other pre-formed fluid may be created from a polar phase, a nonpolar phase, an optional viscosifier, and at least one surfactant.
