Abstract

Production of crude oil from high temperature reservoir from subsurface to surface will reduce the oil temperature and it will lead to fonnation of wax. The wax precipitation is common in petroleum industry which gives challenges to the flow assurance. The major problems that caused by wax formation are reduction of production, increased pressure drop in pipeline, and high risk of getting a pipeline gauge stuck during maintenance operations. It can be very costly to solve the problems caused by wax and may lead to loses. The objective of this project is to develop an thermodynamic model to predict the Wax Appearance Temperature (WAT) by determining the suitable solubility parameters, fusion enthalpies and fusion temperatures. Recognizing the WA T may improve cost saving of crude oil production. Early prevention can be carried out to avoid wax precipitation in the operating facilities and maintain the performance and efficiency of equipments. In order to produce an accurate model in predicting wax forming temperature, the liquid-solid transition factors need to be considered. The thermodynamic model for estimation of W AT is being developed by finding the details of each parameter which will be inserted into MA TLAB for calculation. The effect of carbon numbers, fusion enthalpies and solubility parameters to the model has been obtained. The results of this model have been compared with the existing model. In conclusion, the suitable parameters for the wax prediction model have been determined and a thermodynamic model has been developed to predict W AT and wax amount.
