    摘要: A method for consolidating particulate matter in a well wherein the method comprises the following steps: Injecting a composition into a sand bearing formation, where the composition comprises a curable non-aqueous, homogeneous liquid, an initiator for heat induced production of free radicals, a pot life extending inhibitor for stabilization of free radicals, and optionally an accelerator and optionally a filler wherein said non- aqueous, homogeneous liquid further comprises an at least partially unsaturated pre- polymer selected from the group consisting of polyester and epoxy vinyl ester, and at least one vinyl or allyl containing monomer. Subsequently injecting an aqueous, non- aqueous liquid or a gas for re-establishing permeability of the formation and letting the composition cure by free radical polymerization in the sand bearing formation at a temperature of 0-150° C to form a cured sand consolidating material. The composition as described in the first step of the said method can also be used as a sand consolidation material in general, without following the method as previously described.

    摘要: Reduction of the water permeability within a subterranean formation, particularly within a proppant pack or a gravel pack, can be achieved through the use of a relative permeability modifier (RPM) coated on a particulate material. Methods for reducing the water permeability include providing RPM-coated particulates that contain a RPM coating on the particulates, and placing a treatment fluid containing a base fluid and the RPM-coated particulates in at least a portion of a subterranean formation. The treatment fluid can also contain a companion polymer that serves to further reduce the water permeability compared to that achievable when using the RPM alone.

    摘要: A method of preventing or reducing the migration of fines in a permeable structure such as an earthen formation, comprising contacting said fines with an effective amount of organic copolymer having a molecular weight of from about 1,000 to about 3,000,000 and having recurring structural monomer units formed in a random fashion of the formula:
    wherein

    R 1 and R 2 are independently methyl, ethyl, hydroxyethyl or hydroxymethyl;
    R 3 is an unsubstituted alkylene group having from about 2 to about 4 carbon atoms or a sustituted alkylene group having from about 2 to about 4 carbon atoms and containing a hydroxy group;
    R 4 is methyl or ethyl;
    R 5 is hydrogen or methyl;
    M is hydrogen or an alkali metal; and,

    monomer unit I is present in the range of from about 5 to about 30 weight percent of the copolymer and monomer unit II is present in the range of from about 70 to about 95 percent by weight of the copolymer.
