A bstract : In the work described in this paper, the rheological behavior of hydrate suspensions in an asphaltic crude oil was studied. A P‐T cell adapted to operate as a double cylinder configuration rheometer was used. The results obtained show that the hydrate suspensions studied exhibit shear thinning behavior and thixotropy. This behavior is more visible in suspensions with higher particle content and seems to be related to colloidal interactions between the crystals, which causes aggregation between crystals at low shear rates.
