Rapid engineering solutions for optimum reservoir management strategies in complex reservoirs: A field case study in Southern Mexico

摘要

The objective of this paper is to illustrate the value of rapid engineering analysis as a first step to delineate optimum reservoir management strategies in complex oil fields. Probabilistic material balance, fractional flow calculations, decline curve analysis, and cross-sectional reservoir simulation models are examples of fundamental engineering tools that can be used to quickly optimize a reservoir management strategy in a fraction of the time required for a full-cycle reservoir simulation study. This rapid approach is ideally suited to support fast-pace operational decision making. The proposed methodology is demonstrated with a complex naturally fractured field in Southern Mexico with more than 40 years of production history. The work presented here was used to redefine the short, medium and long-term reservoir management strategies of the field. The details of a recommended new generation water injection programme are also provided.
