New Challenges in Construction and Production Prediction Using Multilateral Well to Develop Ecuadorian Oilfield in Environmental Sensitive Areas

Abstract

Design the multilateral well trajectory in vertical section, like to dual lateral and fishbone wellbore, for drainage M-1 and M-2 reservoir and perform a numerical reservoir simulation to predict the behavior of production for each of the types of multilateral wells. The use of different configuration of Multilateral well technology would help to increase the drainage reservoir area and the oil production form singular well path, also reduce the amount of drilling well for the development oil field, leads directly to the reduction of spatial area required for well-path, which is very beneficial for the environment because it let to decrease the impacts and footprint on the oilfield area, also the use of ML technology helps reduce costs directly related with drilling wells. This study had been divided in two stage to have a better performance. Therefore the first stage is designing a multilateral well trajectory and the second stage is determine the performance of productivity using multilateral well (dual lateral-fishbone) Nowadays the environmental sensitive areas it's a very concern factor to considerer into the design and development oil and gas project, especially when there are a lot of oil reserve proved into this area, therefore during the design phase of the oil project is very important considering the footprint into the oilfield. Also in this work we studied the technical and economical applicability of multilaterall wells in reservoirs with the properties and characteristics of Ecuadorian reservoirs in environmentally sensitive areas, where the theoretical reservoirs were simulated at different scenarios varying values of vertical permeability, length of open zone. Also we built an economical model, using Microsoft Office Excel 2007, for the economical analysis, tacking care account of the cost of all the taxes fixed by the State.

Utilización de algoritmos genéticos para la optimización en el cálculo de variogramas basadas en celdas para la simulación de un yacimiento

“…En este proyecto se desarrollará una metodología basada en algoritmos genéticos como técnica aplicada al análisis de correlaciones de las variables regionalizadas de manera formal y sistemáticamente, que permita resolver en forma óptima los problemas de cálculos variográficos para la caracterización de yacimientos, esto se realizará por medio del uso de una tecnología que ha venido siendo implementada en la última década en el área petrolera como lo es el programa de algoritmos genéticos vinculado a técnicas geoestadísticas y así mejorar la producción en los mismos (Escobar-Segovia, y otros, 2018) (Bone, Aguilar, & Segovia, 2016).…”

Análisis de factibilidad técnico – económico de la conversión de un pozo productor a pozo reinyector de ripios en el campo ESPOL

“…[2] Es por esto que la implementación de técnicas que aseguren la disminución de área de operación y la generación de desechos sea minimizada. Para la reducción de área de afectación una de las técnicas que se ha desarrollado es la creación de pozos multilaterales, [3] presenta una propuesta de diseño de pozos multilaterales en secciones verticales para disminuir el número de pozos y por lo tanto el área de afectación en zonas sensibles de la Amazonía ecuatoriana.…”
