The recent IHS CERAWeek conference in Houston brought ­together high-level executives. Over 5 days of discussions and panel sessions, several key themes emerged about the current state of the global oil and gas industry.

This paper critically investigates the impact of using realistic, inaccurate simulation models. In particular, it demonstrates the risk of underestimating uncertainty when conditioning real-life models to large numbers of field data.

Everhart Energy Technology, a startup company based in Beverly Hills, California, has developed a system it believes will help small to medium-sized operators cope with the reality that, while oil prices have fallen, their electric bills have not.
