ABSTRACT:
A low pour crude oil composition is prepared by incorporating into a waxy crude oil an effective pour depressant amount of an oil-soluble terpolymer, such as a vinyl acetate-ethylene-methacrylic or acrylic acid ester terpolymer. The terpolymer may be added with mixing directly to the heated crude or in hydrocarbon solution such as a solution of the terpolymer in a middle distillate or kerosene. In another aspect, this invention relates to a process for the pipeline transportation of the low pour point crude oil composition previously described.
