摘要： Nanoemulsions have been discovered to be useful to the oil field. More particularly water-in-oil (W/O), oil-in-water (O/W) and other classes of nanoemulsions have found beneficial application in drilling, completion, well remediation and other oil and gas industry related operations. Additionally, nanoemulsions may reduce friction pressure losses, as well as reduce subsidence of solid weight material during oil and gas operations. New preparation methods for nanoemulsions have also been discovered.

摘要： One method for treating cuttings from a subsurface formation may include treating the cuttings with at least one surfactant and at least one stabilizing agent. The method may include contacting the cuttings with the stabilizing agent(s) before contacting the cuttings with the surfactant(s). Another method for treating drill cuttings includes returning the drill cuttings to a substantially water-wet condition by using at least one stabilizing agent to remove at least a portion of a hydrocarbon from the drill cuttings.

摘要： Fluids containing liquid crystal-forming surfactants or polymeric surfactants, or polymers, or complex polymers or copolymers, or graphite nanotubes or Janus particles in a polar and/or non polar liquid, and optionally, co-surfactants, are useful in drilling, completion and production operations to give increased viscosity (solids suspension ability) and/or decreased fluid loss, as compared to otherwise identical fluids absent the liquid crystals. These liquid crystal compositions contain organized micelles. The liquid crystal-containing fluids are useful in completion fluids, fracturing fluids, formation damage remediation, waste management, lost circulation drilling optimization, reducing trapped annular pressure during the hydrocarbon production process, well strengthening, friction and drag reducers, fluids introduced through an injection well for geothermal wells, and the controlled release of additives into a wellbore, at a subterranean formation or at the oil production facilities.

摘要： Nanomaterial compositions are useful for applications in drilling and completion fluids as enhancers of electrical and thermal conductivity, emulsion stabilizers, wellbore strength improvers, drag reduction agents, wettability changers, corrosion coating compositions and the like. These nanomaterials may be dispersed in the liquid phase in low volumetric fraction, particularly as compared to corresponding agents of larger size. Nanofluids (fluids containing nano-sized particles) may be used to drill at least part of the wellbore. Nanofluids for drilling and completion applications may be designed including nanoparticles such as carbon nanotubes. These fluids containing nanomaterials, such as carbon nanotubes, meet the required rheological and filtration properties for application in challenging HPHT drilling and completions operations.

摘要： Single phase microemulsions improve the removal of filter cakes formed during drilling with invert emulsions. The single phase microemulsion removes oil and solids from the deposited filter cake. Optionally an acid capable of solubilizing the filter cake bridging particles may also be used with the microemulsion. In one non-limiting embodiment the acid may be a polyamino carboxylic acid. Skin damage removal from internal and external filter cake deposition can be reduced.

摘要： Nanoemulsion, macroemulsions, miniemulsions, microemulsion systems with excess oil or water or both (Winsor I1 Il or III phase behavior) or single phase microemulsions (Winsor IV) improve the removal of filter cakes formed during hydrocarbon reservoir wellbore drilling with OBM. The macroemulsion, nanoemulsion, miniemulsion, microemulsion systems with excess oil or water or both or single phase microemulsion removes oil and solids from the deposited filter cake. In one non-limiting embodiment, the emulsion system (e.g. single phase microemulsion, nanoemulsion, or other emulsions) may be formed in situ (downhole) rather than produced or prepared in advance and pumped downhole. Skin damage removal from internal and external filter cake deposition can be reduced.

摘要： Single-phase microemulsions (SPMEs) and in situ-formed microemulsions in water-wetting pills may be used to reverse the wettability of subterranean rock previously drilled with an oil-based mud or synthetic-based mud before pumping a high fluid loss squeeze pill or crosslink pill or other water-based pill. This wettability reversal occurs by solubilization of the non- polar material into the microemulsion when the water-wetting pill contacts the non-polar material. An in situ microemulsion may be formed when one or more surfactant and a polar phase (e.g. water or brine), and eventually some amount of organic phase, contacts the reservoir formation and reverses the wettability encountered in the porous media. The microemulsions are effective for reversing the wettability that occurs from non-polar materials which include, but are not necessarily limited to, oil-based mud, synthetic- based mud, paraffins, asphaltenes, emulsions, slugs, and combinations thereof.
摘要翻译：可以使用单相微乳液（SPME）和在水润湿丸中的原位形成的微乳液来逆转先前用油基泥浆或合成基泥浆钻孔的地下岩石的润湿性，然后泵送高流失液挤压丸剂或交联丸或其他水性药丸。当润湿剂接触非极性材料时，通过将非极性材料溶解到微乳液中来发生这种润湿性反转。当一种或多种表面活性剂和极性相（例如水或盐水）和最终一些量的有机相接触储层形成并反转多孔介质中遇到的润湿性时，可以形成原位微乳液。微乳液对于逆转由非极性材料发生的润湿性是有效的，其包括但不一定限于油基泥浆，基于合成的泥浆，石蜡，沥青质，乳液，s块及其组合。
