Reservoir Modeled From Outcrop

There's nothing closer to a rockhound's heart than the historically edifying field trip, where legions of geologists spend days scurrying up and down the outcrop with rock hammer, hand lens and notebook in hand.

Commercially Speaking: How Much Gas Is There?

The Jonah Field in the northern Greater Green River Basin, one of the largest gas discoveries in the last decade and a poster child for basin centered gas. The Standard Draw-Echo Springs Field in the Washakie Basin, which was found in the 1970s and was one of the original fields determined to be a large, basin centered gas accumulation.

Impact of Reprocessing Seismic Data

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?

Natural Increase of Oil Column Buoyancy and the Instability of Caprock Seals

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.

Introducing the New EXPLORER, New Digital Newsletters

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.

US Energy Forecast: Even Cloudier Than Usual

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.
