    摘要: A composition useful for crosslinking phosphate esters in hydrocarbon gels used in formation fracturing performs especially well in cold temperatures, such as temperatures lower than (−)20° C. Methods of making the crosslinking composition and the gel are described; also methods of fracturing subterranean formations. Specific forms of ferric sulfate and ferric ammonium citrate are useful as ingredients of the crosslinking composition.

    摘要: Volatile organics in newly produced oil and gas, and/or condensates and distillates from produced oil and gas, are treated to depress vapor pressure to preserve light hydrocarbons in them when they are in storage vessels. The loss of volatile organics during storage of high gravity oil is minimized by forming a flowable or pumpable gel in the high gravity oil, (and/or condensates and distillates), as they are introduced to a storage vessel. The gel-former may comprise a phosphate ester of one or more low molecular weight alcohols, and a crosslinker including a source of iron or aluminum. Although the gels are flowable and pumpable, they can be broken for transportation from the production site or at another desirable time, returning the hydrocarbon product to its original properties.

    摘要: An under-balanced drilling fluid additive is disclosed which reduces reactive shale and/or clay swelling during under-balanced drilling operations, where the additive includes an effective amount of a choline salt. A method for under-balanced drilling is also disclosed including the step of circulating a drilling fluid including an effective amount of a choline salt to reduce reactive shale and/or clay swelling during under-balanced drilling operations.
