    摘要： A method of performing a squeeze treatment comprises pumping a treatment fluid under pressure through a wellbore into a subterranean formation, wherein the treatment fluid includes a hydrogen sulfide scavenging compound that adsorbs onto the subterranean formation in a region around the wellbore. Production fluids are then allowed to flow from the subterranean formation into the wellbore, wherein the production fluids contact the adsorbed hydrogen sulfide scavenging compound as the production fluids flow through the region around the wellbore, and wherein the production fluids contain hydrogen sulfide that reacts with the hydrogen sulfide scavenging compound to reduce an amount of hydrogen sulfide in the production fluids before the production fluids flow into the wellbore.

    摘要： A method for reducing the effects of biological contamination in a hydrocarbon-containing system comprising the steps of continuously adding a formulation comprising tris(hydroxymethyl)phosphine or a tetrakis(hydroxymethyl)phosphonium salt to the system for one day or more; monitoring the efficacy of the continuous treatment by an assessment of the extent to which there is any effect on the environment that is attributable to metabolic activity of active microbes present in the system; wherein the tris(hydroxymethyl)phosphine or tetrakis(hydroxymethyl)phosphonium salt is added at a concentration of from 1 to 30 ppm based on the total volume of aqueous fluid added to the system, and wherein the formulation is added to the system at a stage to minimize incompatibility with any other chemicals that are added to the aqueous fluid. The treatment disrupts the microbial activity of active microbes in the hydrocarbon-containing system and can prevent or reduce detrimental effects arising from the presence of active microbes in the system.

    摘要： A process for removing a sulfur species from a stream selected from the group consisting of a hydrocarbon stream, an aqueous stream, and mixtures thereof is disclosed herein, which may include introducing a treating mixture into the stream. The treating mixture may include a compound of the general formula selected from the group consisting of:

    or combinations of compound (I) or compound (II). R 1 may be a C 1 -C 30 hydrocarbyl group that is saturated, unsaturated, cyclic or branched, or may contain a heteroatom. 'A' may be an oxygen atom or a methylene group. R 2 may be a C 1 -C 30 hydrocarbyl group that may be saturated, unsaturated, cyclic or branched, or may contain a heteroatom(s) other than C and H. The treating mixture may reduce the reactive sulfur species in the stream. The sulfur species reduced from the stream may be hydrogen sulfide, mercaptans, polysulfides, or combinations thereof.
