NEXT - Applied History Matching

 Ap  A p p l i ed Hi His s t o r y Mat Matc ching Instructor: Mr. Asnul Bahar Bandung, November 6-10, 2017 This course is designed to deliver a practical focus on history matching, uncertainty quantification, sensitivity and optimization workflows. The main purpose is to provide participants with sufficient conceptual background information and tutorial-based experience which give them enough confidence and understanding to reproduce workflows in their daily operations. Both assisted history matching and automatic history matching techniques will be covered and pros and cons of the methods will be discussed. Examples will be presented to illustrate the current state of the art and limitations. The ECLIPSE, FrontSim and Petrel programs will be used to provide hands-on experience with the various techniques.
