3 Takeaways:1. Reservoir sim. Is mandatory and potentially high value - butIncreasing concern that many Res. Sim studies aremisdirected.2. Past “Silver Bullets” have had modest success. Impressivegains but pragmatism also helpful.3. Practitioners should challenge over-complexification and beprepared to apply simple principles ( material balance / decline/ analogue checks).CTSOR 40 Pty of xxLtd
