The key objectives of the workshop are: 1.Participants to bring own challenges with reservoir simulation related issues (for example difficulty with history matching, etc.) and discuss with workshop leaders and other participants to receive inputs/advises on how to overcome such challenges. 2.Workshop leaders will share their experiences & successes with various simulation projects around the world. 3.Participants will get insights on tips and strategy for building effective and successful reservoir simulation models. 4.Meet and share experiences with other participants. 5.Networking with workshop leaders and others. Participants are encouraged to give a 15 minutes presentation of own challenges in the area of reservoir simulation.
