Abstract
Description
Los procesos de recobro térmico han sido estudiados, implementados y mejorados durante varios años. A finales de los 90’s se despertó un gran interés en la inyección de aire en yacimientos de crudo liviano, producto de la implementación exitosa de un procesos denominado High Pressure Air Injection (HPAI), en el Campo Buffalo (USA), que es una variante del proceso de inyección de aire en crudos livianos, especial para yacimientos profundos con bajas permeabilidades y porosidades. Prueba de esto son el Campo West Hackberry (USA), más de cinco proyectos comerciales a lo largo de la Cuenca Williston (USA) y un piloto en el Campo Zhongyuan (China). Adicionalmente se han realizado estudios de factibilidad en México y Argentina. Este artículo presenta un caso de aplicación de la metodología de priorización para la identificación de yacimientos de crudo liviano candidatos a la inyección de aire.Palabras clave: Inyección de aire, Yacimientos de Crudo Liviano, Recuperación Mejorada de Petróleo.
Thermal enhanced oil recovery process has been studied, implemented and improved over the years. In the late 90’s there has been significant interest in the light oil air injection (LOAI) process, since the successful implementation of the process known as High Pressure Air Injection in the Buffalo Field (USA), which is a variation from the air injection in light oil reservoirs, applicable to deep reservoirs with low permeability and porosity. Proof of this are the West Hackberry Field (USA), more than five commercial projects along the Williston Basin (USA) and a pilot in the Zhongyuan Field (China). Additionally, feasibility studies have been also been performed in Mexico and Argentina. This paper shows an implementation case of a methodology proposed previously for prioritization of light oil reservoir candidates to air injection.Keywords: Air Injection, Light Oil Reservoirs, Enhanced Oil Recovery.
