A Neighborhood Algorithm (NA) for Modeling Dual-Medium Scenario Uncertainty from Production Data
Abstract/Contents
- Abstract
- Uncertainty quantification and history matching have been a challenge in reservoir forecasting, especially in naturally fractured reservoirs (NFRs) where the nature of the fractures is unknown resulting in large prior uncertainty. Multiple geological scenarios are generated for NFRs and a single best-fit model is not sufficient for decision-making under large uncertainty. In this report, we propose a neighborhood algorithm (NA) stochastic search method to search for multiple models that match the historical production data rather than producing one single best-fit model. Uncertainty is then quantified by calculating posterior probabilities using the data generated from NA. The method is illustrated with an application to a synthetic reservoir model analogous to fractured reservoirs in the Middle East. NA is proved to be an efficient and a fast way to calculate the posterior probabilities and quantify uncertainty.
