Estudio técnico de reservorio para la ampliación de la inyección de agua en la arena U inferior del campo MDC

Abstract

The present study seeks to analyze technically the expansion of the water injection in the lower U sandstone to areas of the MDC field where pressure drops and production decline occur. The study first considers an evaluation of the current water injection project data in the lower U sandstone using monitoring methods such as: VRR, Hall and Chan curves, oil and water production, intake pressures, %BSW and salinity maps, and isobaric map, which contribute to obtain an idea of the effect of water injection in each of the areas of the lower U sandstone. Subsequently, the analysis of the geology, petrophysics and reservoir of the area with the greatest reduction in pressure and decline in production is carried out, in order to describe the characteristics of the sand and wells in the study area; then the water injection prediction method most appropriate to the characteristics of the area is applied. To evaluate the profitability of the project, a technical-economic analysis is carried out using the financial indicators VAN, TIR and PRI. Finally, the necessary conclusions and recommendations of the project are presented.
