Pasos en la Simulacion de Yacimientos
The design of a reservoir simulation model is influenced by the following factors:

* Type and complexity of the problem
* Time available to complete the study
* Cost of study
* Quality of available data
* Ability of the simulator and hardware.

Planning a Simulation Study

1. Problem Definition.
2. Data Acquisition and Review.
3. Reservoir description and model design.
4. Adjusting history.
5. Prediction.
6. Report.

1. Defining the problem. The first issue to be addressed when carrying out a simulation study is to define the behavior problems and operational problems associated reservoir. To accomplish this you must gather sufficient information about the reservoir and its mode of operation to identify the necessary alternatives with respect to forecasts.

Must be defined clearly and concisely the practical objective of the study. RAs are also required to identify the primary mechanism depletación and recognize that factors dominate the behavior of the reservoir (gravity, heterogeneity, taper, etc.).

If possible, determine the level of complexity of the reservoir model, to begin its design and identify data needed for its construction.

2. Acquisition and data review. The data should be reviewed and reorganized after these have been collected, because these have been obtained for different reasons and usually have not been organized in such a way that makes immediate use.

The review must be conducted carefully and should be consumed as long as necessary to avoid useless work.

3. Reservoir description and model design. The design of a simulation model will be influenced by the type of process to be modeled, problems related to fluid mechanics, the objectives of the study, the data quality of the reservoir and its description, time constraints and the level of credibility necessary to ensure that study results will be accepted.

4. Adjustment History. After a reservoir model is built, it must be tested to determine if you can duplicate the behavior of the reservoir. Generally reservoir description used in the model is validated by «run» the simulator data and historical production and injection compare the calculated pressures and fluid movement with the current behavior of the reservoir.

5. Prediction. Once we have obtained an acceptable history setting, the model can be used to predict the future behavior of the reservoir and thus achieve the goals set by the study.

The quality of the predictions depend on the characteristics of the model and the accuracy of the description of the reservoir.

6. Report. The final step of a simulation study is to translate the results and conclusions in a clear and concise report. The report may be a brief memorandum for a small studio or a large full report for a study at the site.

In the report should include the objectives of the study, description of the model used and present the results and conclusions concerning the specific study.
