Starting in the 1980s people began to see that an efficient way to answer this question was to acquire both P-wave and S-wave seismic data across a rock/fluid system that had to be interpreted.

Even from the beginning, the discovery well gave a hint that the Permian Basin was going to be a major oil province. That well was the Santa Rita #1 – Santa Rita, the patron Saint of the Impossible.

Geology’s role in unconventional natural gas production (via hydraulic fracturing and directional drilling) often is overlooked by the public, but it is a key factor in ensuring that natural gas production is efficient, economic and environmentally responsible.

Hydraulic fracturing technology was pioneered in the mid-1940s by Halliburton, and arguably questionable as to its early success.

The golden oldie: Operators’ eyes tend to light up when talking about the Permian Basin, with good reason – the venerable play is not only still going strong, it keeps providing exciting new chapters to its history.

Shale gas production is booming throughout the United States and the world due to the success of the cutting edge – and in some corners, controversial – drilling technique known as hydraulic fracturing.

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?

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.

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.
