Abstract

The integrated asset modeling has gained popularity in the last years because it has a positive impact on field development, optimization and reservoir management. Especially it has become a must be to properly analyze the interaction between a reservoir and its production facilities or to predict the behavior of several fields sharing a common surface production facility (Ghorayeb, k. 2005).

As a result of the strategic development plan, PEMEX Veracruz Asset has been discovering dry gas fields which must be produced through shared production facilities in order to be economic. This poses a complex operational scenario that demands the use of technology that enables the analysis of the whole system and the interrelation of its elements to support the reservoir management strategies.

This paper describes a case study in which four reservoir models were coupled with a production network model, with the objective to maximize the recovery factor, identify operational problems along the exploitation, and also evaluate the water production impact, through the Integrated Asset Modeling (IAM) enabling the design of different exploitation strategies including compression stages and evaluate them both technically and economically.

Besides it includes a full description of the modeling process with all the assumptions, constraints, solving method and results obtained. This methodology has been successfully implemented adding value to the asset due to a proven improvement in the reservoir management, operational plans and decision making process.
