Plane, transverse MHD flow through a porous structure is considered in this work. Solution to the governing equations is obtained using an inverse method in which the streamfunction of the flow is considered linear in one of the space variables. Expressions for flow quantities are obtained for finitely conducting and infinitely conducting fluids.

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.

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. Para incrementar la producción de los pozos y prolongar la vida de este campo, se propone la selección de pozos candidatos a fracturamiento hidráulico, para ello, es necesario realizar un análisis preliminar de investigación referente al diseño de completación, historial de producción y reacondicionamiento efectuados en cada pozo, formaciones productoras, estimación de sus reservas, correlación e interpretación de registros eléctricos, calidad y tope del cemento, intervalos a punzar 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. ABSTRACT The Gustavo Galindo Velasco field 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. To increase the production of the wells and prolong the life of this field, the selection of candidate wells to hydraulic fracturing is proposed, for which it is necessary to carry out a preliminary research analysis regarding the completion design, production history and reconditioning carried out in each well, production formations, estimation of their reserves, correlation and interpretation of electric logs, quality and top of cement, intervals to puncture and design of fracture. The results obtained from this research allow to approximate 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 profitableness indicators.

The main goal of this research is to evaluate the artificial systems used to produce oil through the machine learning technique with the purpose of selecting a single optimal SLA of section 66 of the Gustavo Galindo Velasco oilfield, to increase production, improve operations, reduce the risks of losses and evaluate the viability and feasibility of the proposal. The present work is based on a descriptive, quantitative and comparative investigation of the different methods of artificial lifting with which it is being produced in the GGV oilfield "section 66". Theoretical research is necessary for the collection of information on the SLAs by BM, HL and plunger or SW. The prediction of the decision tree algorithm gives as a result that the optimal artificial lift system to be implemented in the entire section 66 is mechanical pumping, because the wells that operate with this system obtained a higher production rate during the 2016-2020 period in comparison. to the wells that produce with other artificial lift systems, and in turn generated lower operating and maintenance costs because the interventions carried out inthe wells are low cost, in addition money is saved in fuel, grease, lubricants and spare parts .
