Abstract

In one aspect, a synergistic paraffin inhibitor includes a high-temperature intermediate and a low-temperature intermediate. The high-temperature intermediate has a high crystallization onset temperature, while the low-temperature intermediate has a low crystallization onset temperature that is within a range of about 6° C. and about 30° C. lower than the high crystallization onset temperature. In another aspect, the synergistic paraffin inhibitor is prepared by obtaining a high-temperature intermediate and a low-temperature intermediate. The high-temperature intermediate and the low-temperature intermediate are mixed to form the synergistic paraffin inhibitor, which may be introduced to a crude oil.
