Diseño de un fluido de estimulación con aditivos generados con economía circular.

Abstract

In Ecuador the largest hydrocarbon reserves are heavy and extra-heavy oil. The largest field with production potential is the Pungarayacu field, located in the Napo province. However, up to now it has not been possible to exploit such reserves, apparently due to technical difficulties. In this work we propose the development of a stimulation fluid capable of removing the damage caused by asphaltenes and resins in a heavy crude oil, as well as a control fluid to accompany the stimulation fluid. The properties of the solvents in the stimulation fluid with the reservoir rock will be studied using spectroscopy. The solvents proposed for the dissolution of Pungarayacu extra-heavy crude oil can be used as part of the tandem of control and stimulation fluids for oil wells; since most well interventions require removal of formation damage, which are generated by mobility of asphaltenes and resins of similar chemical characteristics as those found in Pungarayacu extra-heavy crudes, which move along the pores and pore throats. For this reason, it is appropriate to consider the formulation of a mixture of fluids capable of cleaning and removing asphaltenes and resins in drilled well reservoirs that cause formation damage to a well during production.
