Estudio técnico-económico para la aplicación de fracturamiento hidráulico en pozos productores de la arena Ui, en la zona norte del campo Sacha

Abstract

This paper establishes appropriate concepts and parameters for the design of a hydraulic fracturing, as well as the feasibility of its application on the active wells in the North Zone of the Sacha Field and whose production comes from the Lower U sand. In order to achieve this goal, the first step is to characterize the productive sand and evaluate the current situation of the wells through a series of indicators and productivity analysis tools, filtering and selecting those that have the appropriate characteristics to be candidates for the implementation of this technique. Subsequently, and based on the hydraulic fracturing theory, review of well antecedents and well logging results; a right fracture design is elaborated in the selected wells. One of these designs is compared with a real technical proposal in order to validate the obtained results. Finally, to evaluate the development of the proposed job, the increase in wells productivity is estimated and the financial indicators that guarantee the profitability of the investment are presented. Through the obtained results, this paper concludes that there are productive and economic benefits when the candidate wells are properly selected and the hydraulic fracturing treatment is well developed.
