Title: Automated Methodology For Field Performance Optimization Developed With Horizontal Wells
Author: Nakajima L.
Schiozer D.J.
Abstract: The main task of reservoir engineering is the development and management of a petroleum field in order to improve the profitability of a reservoir by raising production rates with minimum costs or increasing ultimate reserves. The performances of many horizontal well projects around the world demonstrate their effectiveness in achieving this objective, especially in offshore fields. However, this type of well has more complicated interaction with the reservoir, since its behavior is a function of a high number of parameters. The purpose of this paper is to present an automated methodology to optimize reservoir performance with horizontal wells, by using numerical reservoir simulation to provide the production forecast. The methodology is developed through the performance analysis for individual wells, group of wells and field. The objective of this analysis is to identify the parameters that define horizontal wells productivity, to realize a comparison between wells performances, and to investigate the causes of inadequate field and wells performance. The analysis is based on selected objective-functions: net present values, cumulative oil, gas and water productions and water injection. The methodology is developed to propose changes to optimize a strategy set previously. A concept of well neighborhood is used to allow simultaneous changes, which yield a lower number of simulation runs.
