ANALYZING THE EFFECT OF WAX DEPOSITION IN PIPELINES AT WELL X USING OLGA SIMULATOR
Main Article Content
Abstract
This design/research discusses wax, with the aim of determining what parameters affect the deposition of wax along the X well pipe network and knowing the starting position of the formation of wax deposition that occurs along the X well pipe network. One of the causes of the decrease in production rate is the presence of a deposit derived from the crude oil content due to changes in the temperature of the fluid which results in the formation of deposits along the production pipeline to the surface. The method used in this research is to use real field data and assumption data from literature studies. The results of this study found that based on the simulations that have been carried out, the parameters that affect the presence of wax deposits along the WIDB-WIDP platform pipe are temperatures that decrease below WAT 103.38 °F. Supported by an increase in wax thickness when the fluid temperature value reaches the WAT temperature value. As well as the back pressure along the pipe flow at well X which causes wax to form before the fluid temperature touches the WAT value. And the composition of the wax content can affect the shape and thickness of the wax in the X well flow based on the assumptions made. The length of the flowline pipe on the WIDB-WIDP platform is 6082.02 ft. The initial position for the formation of wax deposits is on flowline pipes that have different geometries. As a result of this difference in geometry, there is an accumulation of wax. The beginning of this wax accumulation is at the 1501 ft flowline pipe point. There is also a change in the geometry of the pipe along the WIDB-WIDP platform, which causes friction between the pipe wall and the fluid which can result in the accumulation of wax deposition.
