Estudio técnico-económico del incremento de producción obtenido mediante el método de estimulación PerfStim Prime en pozos de la Cuenca Oriente

Abstract

This project is about the implementation of a new technology that permits to increase the productivity index of the wells. This technology applies a shoot technique much more aggressive that stimulates the formation according to its characteristics. This minimizes the damage caused by the impact of the shoots, partial penetration damage and skin factor. In additon, to obtain a greater penetration into the formation and improve the stream geometry, shoot molded charges covered by propellant are used into the formation in order to induce micro fractures into the fractures and interconnect the pores of the formation with the stream created by the charges. Additionally, special fluids for matrix-stimulating microfractures it´s used, and in turn push the entire treatment with nitrogen at a pressure that reaches at least 1.4 psi / ft fracture gradient, achieving acidify formation, minimizing damage and increasing the permeability of the formation. The project will be helpful for a better understanding of technique performed for the first time in Ecuador by the service company.
