  • Publication number: 20220145179
    Abstract: Methods for preparing alkenylphenone corrosion inhibiting compositions may include providing an arylacetone and reacting the arylacetone with formaldehyde in the presence of a strong base catalyst. Corrosion inhibiting compositions may include an alkenylphenone, which may be prepared by a method including providing an arylacetone and reacting the arylacetone with formaldehyde in the presence of a strong base catalyst. Methods of inhibiting corrosion of a steel surface of an oilfield equipment component may include contacting the steel surface with an aqueous solution comprising a corrosion inhibitor. The corrosion inhibitor may include a composition containing an alkenylphenone prepared by reacting an arylacetone with formaldehyde in the presence of a strong base catalyst.

  • Patent number: 11286187
    Abstract: A methods and compositions for inhibiting iron sulfide scale in an oil production system having a well in a hydrocarbon-bearing formation. The method includes the steps of: supplying an aqueous scale-inhibiting solution comprising a water-soluble metal compound and a scale inhibitor, the water-soluble metal compound comprising a metal selected from the group consisting of lead, zinc, and combinations of the same; and wherein the scale inhibitor comprises a compound selected from the group consisting of phosphino polymers, inorganic polyphosphinates, organic phosphate esters, organic phosphonates, organic aminophosphates, polyphosphonates, polycarboxylates, and combinations of the same; and injecting the aqueous scale-inhibiting solution through the well such that iron sulfide scale is inhibited in the oil production system.

  • Publication number: 20210269701
    Abstract: A polymeric scale inhibitor composition and a method for inhibiting metal sulfide scale formation in a well are provided. The composition includes 80-82 mol % of a first monomeric unit, where the first monomeric unit is 2-acrylamido-2-methylpropane sulfonic acid (AMPS). The composition also includes 2-18 mol % of a second monomeric unit selected from N-vinyl formamide, N-vinyl pyrrolidone, and diallyl dimethyl ammonium chloride. The composition further includes 2-18 mol % of a third monomeric unit selected from acrylic acid, methacrylic acid, esters of acrylic acid or methacrylic acid with an alcohol having 1 to 4 carbon atoms, and carboxyethyl acrylate. The polymeric scale inhibitors show superior adsorption characteristics on rocks and their subsequent release behavior allows for scale inhibition over extended time periods respectively at a significant volume of coreflood fluids. They are especially suited for downhole application via field scale squeeze treatments.
