The three-dimensionally complex, highly progradational mixed siliciclastic–carbonate strata of the San Andres and Grayburg Formations have long been the backbone of conventional hydrocarbon reservoir production from the Permian Basin, and significant recovery continues via waterflooding and CO2 injection.

Pity the Permian Basin. Investors complain about disappointing returns from Permian production. Stockholders worry about the financial outlook for operators in the play. Lenders have started to cast a skeptical eye at the basin’s profit potential. So it’s surprising to find that a data-derived solution for addressing the Permian Basin’s current challenges might be readily available. And it’s somewhat startling to hear that, someday, unconventional resource plays in the United States could fly higher than ever.

Some of the world’s largest oil companies have pumped up their shale investments recently, targeting increased future production from shale oil plays. At the same time, some independents have been cutting back on shale spending, in part because of lower oil and gas prices and shareholder demands for improved returns. The result is a not-so-subtle shift toward shale dominance by Big Oil.

More than 20 years ago, Charles Sternbach found himself on the edge of his seat in a conference room where a handful of geologists were sharing fascinating stories about their discoveries, once thought to be out of reach. And, he walked away knowing one thing: These stories, and many more, must continue to be told. And so began his mission to keep them alive and to keep them coming in a forum he would eventually bring to AAPG called Discovery Thinking.

Call it an exploration recovery. Call it a rebound. But it feels like the oil and gas industry is returning to health in fits and starts. That could be because the patient was sicker than we realize. Any measure of how far exploration has come back should take into consideration how far back it started.

Basic. Humble. Old school. Whatever you call them, petrophysical well logs are a workhorse for the oil and gas industry. Today, geoscientists are using machine learning and other artificial intelligence techniques to glean even more information from logs. And a new generation of downhole instruments now provide loggers with more, and more relevant, data

Over the past 10 years, tight oil boosted the United States back to world prominence in crude oil production. Today’s projections tie future U.S. production levels to continued strength in tight oil output, especially from the Permian Basin. Considering the importance of unconventional oil plays in the overall U.S. production picture, it’s useful to examine the outlook for tight oil. And in the Permian Basin, that outlook isn’t as bright as previously thought.

Seismic data are usually contaminated with two common types of noise, namely random and coherence. Such noise, if not tackled appropriately, prevents their accurate imaging. Small-scale geologic features such as thin channels, or subtle faults, etc. might not be seen clearly in the presence of noise. Similarly, seismic attributes generated on noise-contaminated data are seen as compromised on their quality, and hence their interpretation. Noise reduction techniques have been developed for poststack and prestack seismic data and are implemented wherever appropriate for enhancing the signal-to-noise ratio and achieving the goals set for reservoir characterization exercises.

At the recent URTeC conference, I gave a luncheon talk about the importance of the geology within the Permian Basin as it relates to the unconventional and horizontal plays within the basin. As we move into the “mining stage,” one tends to forget that these plays exist because of the geology. Technology allows us to get the oil out, but the geology put the oil in.
