Patent ID: 7541315

Claim:
A method for treating formation fluid from an oil and gas well comprising admixing a paraffin inhibitor composition with a formation fluid wherein the paraffin inhibitor composition consists essentially of: (a) a polymer having the characteristic of inhibiting paraffin crystalline growth; (b) a first solvent selected from benzene, toluene, xylene, ethyl benzene, propyl benzene, trimethyl benzene and mixtures thereof; and (c) a second solvent selected from cyclopentane, cyclohexane, carbon disulfide, decalin and mixtures thereof; wherein component (a) is dissolved in an admixture of components (b) and (c); wherein the polymer having the characteristic of inhibiting paraffin crystalline growth in formation fluid is selected from the group consisting of olefin/maleic esters, olefin/maleic imides, ethylene vinyl acetates, alky phenol resins, alkyl acrylates, and mixtures thereof, and wherein the weight ratio of the first solvent to the second solvent is from about 6:1 to about 1:6.
