Fueled by economic growth and its geological similarities to the Orange Basin in Namibia, Uruguay has attracted ample growth and attention in the energy sector. Its policies have also helped it become a sustainability leader over the past decade.

Production and prospects continue to pour out of the greater Permian Basin-area of West Texas. One growing play echoes the very beginning of the U.S. shale revolution. More than 20 years ago, development of the Barnett Shale in the Fort Worth Basin introduced the world to the practice of combining hydraulic fracturing with horizontal drilling. That became a history-making shale gas play. Today, operators are targeting the Barnett more than 300 miles to the west, in the Midland Basin, where the formation is deeper and oilier.

Analysts, consultants and government agencies have issued their outlook for oil and gas and the rest of the energy industry for 2024. This time around their confidence level is lower than usual, with significant unknowns in supply, demand and price. Here's what to expect and trends to watch.

Since 1984 the Reservoir Characterization Project at Colorado School of Mines has been working on shale reservoir development. RCP began its first study at Silo Field, Wyo., recording the first land 3-D multicomponent (9C) seismic survey focused on characterizing the Niobrara fractured reservoir. The result of RCP’s work led to the first horizontal drilling in the Rockies in 1990 and led to the drilling of the most successful well in the field.

This is my final contribution to the AAPG EXPLORER as president of the Energy Minerals Division and it has been an honor. As with many other division presidents, I feel safe in the assumption that I did not achieve as much as I had hoped but take solace in the fact that as least some forward progression was made. It is in this that I would like to make my final contribution by addressing three EXPLORER articles in the last issue that reference issues that are of great concern to me: These three articles could not have been published at a better time.

We have seen many changes in the oil and gas industry since AAPG’s founding more than 100 years ago. AAPG has also changed along with the industry in response to these changes. Our industry’s focus on various plays and areas constantly varies, while shifting product prices and sweeping changes in public opinion and governmental policy have a major impact upon companies of all sizes, as well as the geoscientists working for them.

The processing of land seismic data entails a series of steps through which the data passes, including sorting, static correction, deconvolution, residual static correction, velocity analysis, migration, stacking, filtering and scaling. Some tasks, such as velocity analysis, are interactive, while others are automated. The processing of seismic data from the same area often follows the same proven series of steps or sequence, barring any unforeseen issues that need to be addressed. Such a sequence of tasks designed to process data from their initiation to completion is referred to as a “workflow.”

National and international energy companies today face enormous pressure from government, shareholders and society to meet increasing demand and deliver profits while meeting the United Nations Sustainable Development Goals and progressing toward a transition away from fossil fuels. The Energy Trilemma – the capacity to provide energy security, energy equity and environmental sustainability simultaneously – is a term developed and measured by the World Energy Council since 2010. Whether they use “Energy Trilemma” or another term, industry leaders face daily decisions about how to provide reliable, sustainable energy for all while reducing CO2 emissions and developing cleaner energy sources.

Alaska’s North Slope is the best conventional onshore oil play in the world. That’s according to Bill Armstrong, CEO and president of Armstrong Oil and Gas, Inc. And, he will give no quarter on his belief about how robust the future is for the North Slope’s prospects. In short, Armstrong calls the area “incredible.”

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.

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.

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?
