Abstract: In the quest of energy resources, oil exploration and production is in its peak activity during the present era. Oil and gas fields worldwide are reaching maturity, pushing operations to more challenging areas. During transportation of oil through a pipeline, when the oil temperature is higher

than the pipe wall temperature, there will be a dissolved wax concentration gradient between the bulk oil and pipe wall. Crystallization and deposition of waxes occurs if the wall/interface temperature falls below the wax appearance temperature (WAT) of oil being transported. It can affect single wells along with transportation pipelines that are critical to the safe supply of oil to processing facilities. Wax deposition is a very complex phenomenon. Proper pipelines and production equipment is one of the main challenges in Flow Assurance. As remedial costs increase with decreasing production, wax precipitation and deposition significantly influence economy for a field.There are several wax

deposition models with different approaches on modeling wax deposition. The basic wax deposition models are Rygg, Rydahland Ronningsen (RRR) model, Matzain model, Hydro model and University of Michigan model. The important element is to illustrate how wax deposition models  predict wax build up. The present study intends to analyse the effect of wax deposition on pipelines by RRR model and estimate the temperature profile during summer and winters in entire length of pipeline using MATLAB software &compares it with real time SCADA results. It also estimates and compares the pressure drop and volume of wax deposited along the length of the pipeline.
