Key words: oil treatment and transportation, pour point depressant, high-paraffin crude oil, offshore field
The article describes complex methods to ensure transportation of the high-paraffin crude oil by the example of Dragon field, located in South Vietnam offshore. The methods include optimization of the oil treatment technology by chemical agents (pour point depressants and de-emulsifiers); implementation of the depressant additives solutions for the more effective impact on oil; rehabilitation of the throughput capacity of pipelines; break of the water-oil emulsions to decrease the viscosity of the transported oil. Example of the non-heat-insulated pipeline RP-1 – FSO-3 explains how implementation of the complex methods leads to the positive results in ensuring safe transportation of the produced product.
