Believe it or not, gasoline and other hydrocarbon products are better bargains now than they were 50 years ago, and given the improved fuel economy of modern cars we probably spend a lower percentage of our income on gasoline than we did back then.

It isn’t news to anyone that prediction is difficult, especially when it’s the future (as a great man once said). Uncertainty and unpredictability are just a part of the job of tracking and predicting the future supply and demand of energy. That being the case, when energy analysts say that the current level of uncertainty is particularly high, it might be easy to dismiss it as a “dog bites man” story. It isn’t.

Perhaps you did a double take pulling the April issue of EXPLORER from the mailbox. What is this? If you joined AAPG in the last 40 years, you’ve only known EXPLORER in its long-standing tabloid format. It worked well for many years as our advertisers – particularly seismic companies – loved the large format and the ability to display their data on a sweeping canvas. For readers, it was a little more awkward.

A new type of buoyancy model can be used to understand the source of residual oil zones, both thick and thin, to help determine the likelihood that economically viable recoverable oil resides in transition zones of imbibition reservoirs. Application of a buoyancy and breech model will fill a void in reservoir characterization. It will help distinguish between TZs and ROZs, the first of which allows application of primary and secondary (waterflooding) oil recovery methods and the second of which requires more difficult CO2-enhanced oil recovery projects.

Advancements in processing and imaging techniques have continued over the last several decades, which have gradually improved the quality of the processed surface seismic data. When the quality of the existing seismic data is not adequate to perform an interpretation task reasonably, then the interpreter looks for other options. Is it feasible to acquire a new survey? In the absence of an improved survey, will reprocessing of seismic data be a good option?

The Casablanca oil field, discovered in 1975 and located on the Mediterranean shelf edge, has been greatly significant in the world’s offshore oil industry activity, besides being by far the biggest oil field in Spain.
