This paper has the objective of presenting new technology, ensuring flow in the extra heavy crude field. The idea of this paper is to outline a successful pilot study carried out in the Colombian Eastern Llanos region where the effect of chemical product (flow improver) is exposed during the production of fluids from the pilot study well and the reduction of naphtha injected into the wellhead (diluent used for the movement of the surface crude). As the main fundamental, the modification of the rheology properties of the crude through change in apparent viscosity due to the effect of loads and interfacial molecular tension within the fluid, enabling improved mobility of fluids from the reservoir to production facilities via surfactant resins that interact with the colloidal particles in the crude thus reducing its viscosity. The pilot is divided into two phases, the first phase consists of determining which of the two flow improvers produces the best performance, and the second phase consists of the application of the selected flow improver to reduce the dilution of naphtha, that is used during the processing of crude to reduce its viscosity.

Within the study, a financial evaluation is presented for each of the pilot phases, including a revision of the ESP pumps efficiency within different scenarios.

Finally one of the most telling conclusions is mentioned, as the flow improver enables the possible reduction of naphtha injection by dilution in values close to -30%, increasing well production to close to 40%.
