Análisis de eficiencia energética en combustibles para sistemas de generación eléctrica aislada en las plataformas de pozos de producción de crudo 420, 470 y 480 en el Campo Sacha - Bloque 60. Análisis técnico – económico

Abstract

In this present work an energy efficiency analysis of fuels of the three production platforms of crude PAD 420, 470 and 480 was carried out in the Sacha field - Block 60, since at the present time there exists own and rented electricity generation that uses diesel as fuel for the operation of bottom equipment. The operation cost is 10,000 USD a day for the three PADs. These platforms have surface facilities to separate natural gas and burn it in lighters with the aim of not having problems in the pumps at the moment of the crude oil transference to the stations. By means of the methodology, ten-year data was obtained on volume of natural gas of the platforms, as well as on the main components for the use of an equipment that meets these conditions. As an experimental part, gas chromatography analyses were carried out on each platform to analyze its fuel components, as well as the net power for electricity generation required by the bottom and surface equipment. Ecuadorian companies presented offers for the current conditions of each platform where there are Bi fuel equipment, turbines and gas engines. Therefore, a technical-economic analysis of the current costs was carried out: (PAD 420: $ 0,17 kWh; PAD 470: $ 0,17 kWh; PAD 480: $ 0,13 kWh) and applying the investment of new technologies, it would be: (PAD 420: $ 0,046 kWh; PAD 470: $ 0,061 kWh; PAD 480: $ 0,10 kWh), reducing to 4.000 USD a day
