An increasing number of companies, in an increasing number of places around the world, consider horizontal drilling as an option in all kinds of plays. Through May 1999 Denver-based IHS Energy Group's databases contained records for 20,430 horizontal wells in 67 different countries.

Area-wide lease sales, inaugurated in 1983, provided the oil industry an opportunity to explore for oil and gas in the deep water Gulf of Mexico, a southern extension of the oil-rich offshore Louisiana shelf province.

An unfortunate fact of geology is that most datasets, including seismic, rarely allow for a unique interpretation of a geological problem.

Looking deep for new oil -- a strategy that Tri-Valley Oil and Gas is implementing with EKHO No. 1 -- could make them America's deepest oil producer. Spudded Feb. 7 it is on its way to the projected total target depth of 19,500 feet.

On the arid high plains of northeast Wyoming, the town of Gillette has become a bona fide boomtown. And it's coalbed methane creating the frenzy. The Powder River Basin has become the site of the hottest natural gas play in the country, a region most so-called experts wrote off as a wasteland for the gas.

Coalbed methane research and development has been a big story for over 20 years with virtually all the focus on the western United States. But what many folks don't know is that small 'mom and pop' shops have been quietly pioneering coalbed methane production in the Arkoma Basin in southeastern Oklahoma.

The special EXPLORER: A Century issue illustrates how at times the 'Story behind the story' is better than the story itself. In an effort to capture this flavor of exploration science and business, Marlan Downey describes his memories of some of the interesting fields found by teams he has been associated with during more than 40 years of exploration and production.

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.

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?

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.

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.

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.
