  • Intensified corrosion inhibitor and method of use
    Patent number: 5543388
    Abstract: Elemental iodine is used to improve the performance of conventional corrosional inhibitors in oil field acidizing operations. The iodine, because of its solubility, may be used in a formulation which includes a corrosion inhibitor and surfactants dissolved in a suitable organic solvent.

  • Stimulation of coalbed methane production
    Patent number: 5470823
    Abstract: A coalbed formation is stimulated to improve the recovery of methane which involves injecting into the coalbed formation an aqueous acid solution containing an organic amphoteric tertiary ammonium compound having from 1 to 3 tertiary ammonium groups, each N of which contains at least one C.sub.3 to C.sub.4 unsaturated carboxylic acid group, and wherein the compound contains a terminal benzyl or C.sub.5 -C.sub.19 alkyl group.
    Type: Grant

  • Amine derivatives as corrosion inhibitors
    Patent number: 5322630
    Abstract: A method of acidizing a subterranean formation with an acqueous acid solution wherein the acid solution contains corrosion inhibiting amounts of an amine derivative prepared by reacting an unsaturated carboxylic acid with (a) fatty amine or polyamine, or (b) a fatty amido amine or polyamine, or (c) a fatty imidazoline amine or polyamine. The derivative is characterized by the absence of primary amino groups, and preferably contains only tertiary amino groups.

  • Corrosion inhibitor and method of use
    Patent number: 5130034
    Abstract: A corrosion inhibitor for an acid well treating composition includes first metal ions including Sb, Cu, and Bi complexed with a quaternary ammonium compound and second metal ions complexed with a quaternary ammonium compound. The complexed compounds may be prepared and introduced into the acid or the first metal ions may be introduced directly into the acid system.
