Heavy crude oil, which is found within the pore of carbonate reservoir rocks, represent a significant portion of the oil reserve of the northern Iraqi oil fields. Production from heavy crude oil wells is usually associated with material deposition that results in reduction in production rate or blockage by forming obstruction inside the well and/or surface facilities and connecting lines. Predicting future deposition profiles for asphalting, wax and scales in heavy oil systems can help in avoiding flow assurance issues and keep production continuous. Therefore, this study came to predict deposition profiles within a heavy oil system using OLGA Commercial simulator and fluid characterization software. This study investigated the deposition profiles and trends and it will help the field operator to schedule remedial or work over plans that best suits the depositions in place and avoid production interruption of unplanned downtimes. Results showed severe asphaltene deposition using different models, reaching as high as 19 mm in the well, on the other hand wax showed mild deposition not exceeding 1 mm and scale deposition was around 2.6 mm in case of 50% water cut. Furthermore, asphaltene alone will contribute to 27% production loss in the future; this is even without considering the additional pressure loose that is induced due to irregular deposition shapes.
