Wax components in a crude oil start to precipitate when the Surrounding temperature is lower than the wax appearance temperature. When wax gel develops under static conditions, a certain amount of pressure is needed to overcome the yield strength of the gelled oil in the pipeline for restart. It is shown that paraffinic components contribute to the evolving gel strength of the oil when cooled below the Pour point. The gel strength was determined by the measurement of yield stress with and without subjecting the samples to creep stress. The existence of primary creep, secondary creep, and tertiary creep, was observed under isothermal conditions depending on the magnitude of the stress applied. This Study explores the effect of prior creep stress with and without subsequent cooling of the samples. No significant degradation (reduction in yield stress) was observed after prior creep of the gelled oil at the same temperature. In the case of the subsequent cooling, applying prior creep stress application results in the dramatic increase of gel strength.
