A novel test procedure for measuring hydrate dissociation conditions is outlined. The method is utilising piezoelectric properties of a quartz crystal through a Quartz Crystal Microbalance (QCM) set-up. Experimental results, using the novel procedure, are compared with literature data and benefits from the method are discussed. A state of the art computer model, simulating hydrate formation with respect to salts and inhibitors is described. The model is validated using literature data for a variety of real reservoir fluids in the presence of formation water, and the organic inhibitors, methanol and ethylene glycol.
