Flow assurance of crude oils

One of the main problems in the petroleum industry is the precipitation of different species (waxes, asphalthenes and scales) when the conditions of temperature, pressure and/or pH are modified. The presence of these solids and its accumulation reduces the flow line section, causing the blockage of filters, valves and even pipelines, increasing pumping costs, and reducing or even stopping oil production or transport. These problems are included in the general field of flow assurance and in our group the research is focused on the study of the wax, asphalthene and scale precipitation. A correct study of these processes requires not only the quantification of the precipitated solid, but also further characterization. Different methods based on experimental techniques (DSC, NMR, GC-MS…) have been developed in our research group. The aim of all our activity in this area is to obtain experimental information to be included in models capable of predicting flow assurance problems and, thus, anticipate possible solutions.
