MARTINI, R. F.; SCHIOZER, D. J.  e  NAKAJIMA, L.. Use of quality maps in reservoir management. J. Braz. Soc. Mech. Sci. & Eng. [online]. 2005, vol.27, n.4, pp.463-468. ISSN 1678-5878.  http://dx.doi.org/10.1590/S1678-58782005000400016.

The definition and management of a production strategy for petroleum fields is one of the most important tasks in reservoir engineering. It is a complex process due to the high number of parameters, operational restrictions and objectives involved, and due to uncertainties in geological and economic scenarios. This work shows an important tool to improve the performance of such a process, called quality map. Quality map is a tool that indicates the production potential of each place of the reservoir, combining several parameters that influence oil recovery efficiency. It serves as a visualisation tool and as a quality index distribution allowing the automation of production strategy definition. The case studies presented in this work involve numerical simulation of horizontal wells in offshore reservoir models. It is observed that quality maps constitute a powerful tool that can be used (1) to locate wells and (2) to speed up the optimisation process by efficiently allowing the analysis and quantification of several parameters and their influence on the reservoir exploitation.

Palavras-chave : Quality maps; production strategies; optimisation; horizontal wells; reservoir simulation.
