Methods for treating paraffins, iron sulfide, hydrogen sulfide, and/or bacteria in subterranean operations and operations involving the production and/or transportation of oil and gas are provided. In one or more embodiments, the methods include contacting a surface comprising at least one paraffin deposit and at least one iron sulfide deposit with a treatment fluid comprising a paraffin dissolver and acrolein; and allowing the treatment fluid to at least partially dissolve or degrade the paraffin deposit and the iron sulfide deposit.

Methods of treating paraffins, iron sulfide, hydrogen sulfide, and/or bacteria

Included are compositions, methods, and systems for producing and using winterized paraffin inhibitor solutions. An example composition comprises a paraffin inhibitor solution; and an additive comprising a first portion and a second portion; wherein the first portion is selected from the functional groups consisting of sulfo, phosphate, phosphonate, ester, carboxyl, hydroxyl, and any combination thereof; wherein the second portion is selected from the functional groups consisting of linear alkyl, branched alkyl, alkyl phenyl, ethoxylated branched alkyl, propoxylated branched alkyl, and any combination thereof.

Additive to decrease the pour point of paraffin inhibitors

Methods for the use of zinc ammonium carbonate as a scavenger of sulfur-containing species encountered in oilfield operations are provided. In one embodiment, the methods include introducing a sulfide scavenging additive including zinc ammonium carbonate into at least a portion of a conduit through which a potential sulfur-containing fluid is flowing.
