摘要： The present invention relates to a two-step process to produce oil or gas from a subterranean formation wherein in a first step the subterranean formation is treated with an aqueous composition containing a chelating agent selected from the group of glutamic acid N,N-di-acetic acid or a salt thereof (GLDA), aspartic acid N,N-diacetic acid or a salt thereof (ASDA), methylglycine N,N-diacetic acid or a salt thereof (MGDA), and N-hydroxyethyl ethylenediamine N,N′,N′-triacetic acid or a salt thereof (HEDTA) and wherein, in a next step, in the outlet streams from the subterranean formation the aqueous phase is separated from the non-aqueous phase.

摘要： Several methods and devices are provided herein to generate shock waves that are used in the oil industry for well drilling, hydrocarbon or gas exploitation, fracking process or improved oil recovery (IOR), enhanced oil recovery (EOR), cleaning of process waters, oil spills byproducts and oil pipes, which can be used as independent systems or as auxiliary systems concomitantly with other existing technologies. The different devices consist of generating shock waves utilizing either one or more laser sources, or a self-generated combustible gas supply, or a micro-explosive pellet, or piezocrystals, or a piezofiber composite structure.

摘要： Compositions comprise nonionic fluorinated polymeric surfactants and solvent. The solvent comprises: at least one of a polyol or polyol ether, wherein the polyol and polyol ether have from 2 to 25 carbon atoms; and at least one monohydroxy alcohol, ether, or ketone having from 1 to 4 carbon atoms, or a mixture thereof, wherein the solvent is capable of at least one of solubilizing or displacing brine or condensate in the hydrocarbon-bearing clastic formation. Embodiments of the compositions are useful in recovery of hydrocarbons from hydrocarbon-bearing clastic formations that contain brine and/or condensate.

摘要： Compositions containing a mixture of microcapsules and a bulk polymer, where the microcapsules have an oil field chemical contained within the microcapsules are described. The microcapsules can be present in a variety of configurations. The microcapsules contain a core or a micro-matrix containing the oil field chemicals. The core or micro-matrix can be surrounded by one or more polymeric shells, where each shell contains at least one polymer that affects the release of the oil field chemical from the composition. The compositions provide for the sustained release of an oil field chemical into fluid in an oil field reservoir over long periods of time. Methods of making the compositions and articles containing the compositions are described. Methods of tracing the movement of fluid in a hydrocarbon reservoir using the compositions, and methods of providing for the sustained release of oil field chemicals are also described.

摘要： A method of treating a subterranean formation comprises forming a storable aqueous suspension comprising a carrier fluid, a superabsorbent polymer, a proppant the proppant being suspended in the carrier fluid as a substantially perfectly supported particulate; diluting the storable aqueous suspension in-line to a desired concentration; and introducing the diluted storable aqueous suspension into the subterranean formation. A sand control method is also disclosed.
