摘要： 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.

摘要： 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.

摘要： 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.
摘要翻译： 纳米乳液，微乳液，微乳液，具有过量油或水的微乳液系统（Winsor I，II或III相行为）或单相微乳液（Winsor IV）改善了使用OBM在油气藏井眼钻井过程中形成的滤饼的去除。 这种滤饼和它们的颗粒可以接触，冲击并影响钻柱的移动，从而导致“卡止管”状况。 具有多余油或水或两相或微相乳液的微乳液，纳米乳液，微乳液，微乳液系统从滤饼中除去油和固体，从而将钻柱从其卡住状态释放出来。 在一个非限制性实施方案中，乳液体系可以在现场（井下）形成，而不是预先生产或制备并在井下泵送。

摘要： A base fluid may contain nanoparticles where the base fluid may include a non-aqueous fluid, an aqueous fluid, and combinations thereof. The fluid may have a resistivity range of from about 0.02 ohm-m to about 1,000,000 ohm-m. The non-aqueous fluid may be a brine-in-oil emulsion, or a water-in-oil emulsion; and the aqueous fluid may be an oil-in-water emulsion, or an oil-in-brine emulsion; and combinations thereof. The addition of nanoparticles to the base fluid may improve or increase the electrical conductivity and other electrical properties of the fluid. The fluid may be a drilling fluid, a completion fluid, a production fluid, and/or a stimulation fluid.
