Wax and gel control for waxy crude from infill wells by using pour point depressant

Transportation of Hydrocarbon through pipelines in waxy residue is a challenging task and expensive due mainly to high wax content and gelling formation. The application of Pour Point Depressant (PPD) is one of the mechanisms to improve the flow properties of waxy hydrocarbon at low temperatures whi...
