|Title:||Field Development Projects Optimization Integrated To Risk Analysis|
|Abstract:||Field development planning is a very complex process due to uncertainties, related to the restricted amount of information available for the high number of variables with dynamic behavior. An appropriate evaluation of these uncertainties in the process often requires reservoir simulation associated to optimization algorithms for the optimization of a non-linear objective-function previously stated, regarding the objectives for the project. Considering the main particular aspects of the objective-function, manual procedures usually are adequated for the optimization of a recovery strategy although they require excessive time from the professionals involved and may not consider all the necessary scenarios in order to avoid long times for projects planning. Some tests have been published with the objective of developing an automatic process but, until this moment, they demand a very large amount of simulations and are unfeasible for actual reservoirs. The approach for field development plan selection proposed in this work takes advantages of both approaches and is composed by a sequence of manual and automated procedures. This enables to integrate the parameters definition for the development plan to a risk analysis (technical, operational, geological, economic, etc.). The procedure for field development plan selection can still be integrated with an adequate decision analysis using, for example, multi-attributes utility theory. The main idea is to propose a procedure that can be applied to a large set of reservoirs, providing the fundamentals to choose the most adequate choice for the initial field development, regarding the risks related and objectives classification for the project. The procedure was applied to an example based on a real field and the results, obtained with a low computational cost, were adequate for decision taking respecting the objectives stated to the project.|
