Description

Assisted History Matching (AHM) is a systematic procedure of modifying parameters of a reservoir model to reproduce its dynamic response. Unlike traditional history matching (HM), where non-systematic manual adjustments on few engineering parameters are made on a single model to match the production data, AHM is part of an integrated study where engineering and geological consistent modifications are made to a reservoir model with the aid of efficient optimization techniques allowing the incorporation of multiple data types, such as production and 4D seismic, while also providing a vehicle for uncertainty assessment.

During the last decade, Shell has developed a number of methodologies to computer-automate the process of updating the large-scale reservoir parameters. These methodologies have been standardized and replicated in multiple fields and include assisted parameter estimation, which uses MCMC sampling techniques with experimental design-based proxies, and model maturation, which uses (adjoint) gradient-based updates to identify and correct (major) omissions (under-modeling) in the static and dynamic model. In this presentation, these methodologies will be presented and the results of their application in some field examples will be demonstrated.

Jose Villa is a senior reservoir engineer in the Global Water Flood Deployment team at Shell International E&P in Houston, TX. He is responsible for the deployment of assisted history matching technologies in Shell fields worldwide. Before this position, he was a reservoir engineer in the Dynamic Reservoir Modeling team providing workflow consulting and support on Shell reservoir simulation workflows. Prior to joining Shell in 2007, Jose was a reservoir engineer at PDVSA Intevep where he conducted reservoir modeling studies for a number of fields in Venezuela.  Jose Villa holds a Bachelor's degree in Petroleum Engineer from Central University of Venezuela (1999), and a Master's degree in Petroleum Engineering from Stanford University (2003). Jose also serves in the committee of the SPE GCS Reservoir Study Group since 2011.
