A combination biocide (Glutaraldehyde or OPA), quaternary phosphonium biocide (preferably TTPC), alcohol (preferably isopropyl alcohol), and functional excipients for the oil and gas recovery industry. The functional excipients for the oil and gas recovery industry are a cellulose type proppant, a poloxamer wetting agent, a friction-reducing pluronic block copolymer, a drag reducing agent such as polyethylene oxide, and a flocculating agent. The OPA may be of the dialdehyde C6H4(CHO)2 form, and the Glutaraldehyde of formula C5H8O2. Both will produce an inherent bacteriostatic effect and lower surface tension and thus aids in the spread of the TTPC on the biofilm covered surface where it is readily absorbed by the negative surfaces of proteins and bacteria. It thus serves as a binding agent between the TTPC and the application surface. The foregoing constituents are combined in preferred concentrations within acceptable ranges to provide a synergistic biological chemical complementarity system.
