FQS THPS75® (FQS-5000)

1 of 1 products in this brand
FQS THPS75® (FQS-5000)​ is a no foaming oilfield biocide with a very low freeze point that makes it ideal for application in colder climates. FQS THPS 75®​ is a 75% aqueous solution of THPS (tetrakishydroxymethyl phophonium sulfate,) which has many advantages over traditional industrial biocides. FQS THPS 75®​ is effective against a broad spectrum of microorganism in both acid and alkaline environments. It is extremely effective against sulfate reducing bacteria (SRB) which is particularly troublesome in the oilfield, causing both corrosion and the release of toxic gas. FQS THPS75®​ has also been shown to dissolve iron sulfide and reduce formation souring.

    In oilfield applications, FQS THPS 75®​ displays excellent activity against problem microorganisms, particulary sulfate reducing bacteria (SRB). FQS THPS75®​ can be used in applications where microbiological contamination is present, including injection water, topside system, drilling muds, packer fluids, completion and workover fluids, pipeline protection and storage. It is insoluble in organic materials and remains in the aqueous phase of oil/water mixtures.
