COURSE OVERVIEW
Artificial neural networks combined with good geological input data can greatly improve predictability of reservoir parameters and produce more reliable reservoir models. Geological and petrophysical control on data handling and interpretation of results is essential in achieving good results. This 3-day training course will focus on Artificial Neural Networks (ANN) and how this can assist in predicting different reservoir parameters in uncored wells. Participants will learn how to use the Tiberius ANN software and associated macros. A basic introduction to ANN will be given, followed by data gathering, data preparation, running and testing the models, interpreting the results, and a discussion on possible pitfalls. The aim is that course participants will be able to run their own ANN model. This will be achieved through several exercises that cover the entire process from gathering input data to developing, interpreting and testing the models. This will be followed by blind-testing the models against a new well. Finally, the developed ANN model will be applied to uncored wells to improve regional predictability of reservoir parameters.

INSTRUCTOR
Arve Lønøy
Arve Lønøy has 37 years of experience as a carbonate geologist within exploration, production/field development, and research. He also has 6 years of experience on siliciclastic North Sea reservoirs. His main specialty is carbonate sedimentology and diagenesis with special emphasis on reservoir characterization. He has developed several proprietary techniques for static reservoir modelling. Arve published (AAPG 2006) a new pore-type classification system that is applied in prediction of permeability, effective porosity, saturation heights and HC contacts. The predictions are further aided by the use of artificial intelligence, using a time-efficient methodology that he has developed. This new methodology for reservoir characterization, and how it is applied in reservoir modelling, was approved by Beicip-Franlab in 2012 audit.
