Recently we have investigated and modelled a number of the heavy hydrate formers, i.e., benzene, cyclopentane, methylcyclopentane, cyclohexane, methylcyclohexane, isopentane, and 2,3-dimethylbutane. This work reviews some of the previous findings and investigates the effect of four of the above compounds on the hydrate free zone of real reservoir fluids. The preliminary results show that the effect of heavy hydrate formers cannot be ignored and in some cases, they reduce the hydrate free zone significantly.
