Abstract
Description
El Campo Gustavo Galindo Velasco ubicado en la provincia de Santa Elena, ha comenzado a mostrar signos de envejecimiento o madurez, denominándose campo maduro debido a la reducción de la presión del yacimiento, lo que ocasiona una disminución en la producción de los pozos.
El fracturamiento hidráulico es una técnica de estimulación que permite obtener, mediante la creación de fracturas o canales que mejoran la interconexión de la permeabilidad en la formación, el aumento de la conductividad y el área de flujo de los fluidos hacia el pozo, incrementando su producción y prolongando la vida de los campos maduros.
En la actualidad, para emplear esta técnica de estimulación, es necesario realizar un análisis investigativo del historial de producción y reacondicionamiento efectuados en cada pozo, estimación de sus reservas, interpretación de registros eléctricos, calidad del cemento y diseño de fractura.
Los resultados obtenidos de la investigación, permiten aproximar el incremento de la producción después de efectuar el fracturamiento hidráulico en los pozos seleccionados y el análisis económico respectivo del proyecto, mediante el uso de los indicadores de rentabilidad.
The Campo Gustavo Galindo Velasco located in the province of Santa Elena, has begun to show signs of aging or maturity, being called mature field due to the reduction of the reservoir pressure, which causes a decrease in the production of the wells. Hydraulic fracturing is a stimulation technique that allows obtaining, by means of the creation of fractures or channels that improve the interconnection of the permeability in the formation, increase of the conductivity and area of flow of the fluids towards the well, increasing its production and prolonging the life of mature fields. Today, to employ this technique of stimulation, it is necessary to carry out an investigative analysis of the production history and reconditioning carried out in each well, estimation of their reserves, interpretation of electric logs, quality of the cement and design of fracture. The results obtained of the research allow approximating the increase in production after performing the hydraulic fracturing in the selected wells and the respective economic analysis of the project, through the use of profitability indicators
