  • Publication number: 20150031588
    Abstract: Nanoemulsions, miniemulsions, microemulsion systems with excess oil or water or both (Winsor III) or single phase microemulsions (Winsor IV) may be formed in situ during hydrocarbon recovery operations after drilling with OBM or SBM using one or more fluid pills. 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 in situ-formed fluid may be created from a polar phase, a nonpolar phase, at least one viscosifier, and at least one surfactant.

  • Patent number: 8415279
    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.

  • Patent number: 8091644
    Abstract: Nanoemulsion, macroemulsions, miniemulsions, microemulsion systems with excess oil or water or both (Winsor I, II or III phase behavior) or single phase microemulsions (Winsor IV) improve the removal of filter cakes formed during hydrocarbon reservoir wellbore drilling with OBM. Such filter cakes and their particles can contact, impact and affect the movement of the drill string undesirably resulting in a “stuck pipe” condition. The macroemulsion, nanoemulsion, miniemulsion, microemulsion systems with excess oil or water or both or single phase microemulsion removes oil and solids from the filter cake, thereby releasing the drill string from its stuck condition. In one non-limiting embodiment, the emulsion system may be formed in situ (downhole) rather than produced or prepared in advance and pumped downhole.

  • Publication number: 20060272815
    Abstract: A gravel packing fluid and method for gravel packing a wellbore using a gravel packing fluid comprising an invert emulsion comprising oil as an external phase, clear brine as an internal phase, and a quantity of emulsifier effective to produce a stable invert emulsion, the external phase of the gravel packing fluid further comprising gravel wetting agent.
