Determinação do número ótimo de poços produtores de um reservatório black-oil e sua avaliação econômica

Abstract

The purpose of this study is to determine the ideal number of fuel wells for a black oil reservoir, based on the development of a simulator that aims to analyze the behavior of the reservoir production, together with an economic analysis to find the best possible scenario. For these purposes, the simulator was developed using Microsoft Excel spreadsheets, programmed from a very simple methodology, but with the capacity to realize the economic pre-development of a black-oil. Regarding the simulator modeling, the General Materials Balance reservoir was used, for which only the black oil fluid and a stable flow regime were considered. Based on the reservoir behavior model and the oil production, an economical engineering study was carried out for ten different scenarios, each one with different number of wells, and its economical analysis. For an economic evaluation, some economic indicators were considered, such as the Net Present Value (VLP), Internal Rate of Return (IRR) and the maximum return time. Based on the parameters adopted in the reservoir, the study reveals that the best scenario is for 8 producing wells, once it reached the highest NPV, a good IRR and a low return time
