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.

From high-altitude, windswept prairies in southwestern Wyoming, the span of the powerful Wind River and Wyoming Ranges can be seen in the distance. This is home to the Pinedale Anticline Project and the Jonah Field, located in Sublette County, Wyo. In 2000, this was the site of one of the most productive gas fields in the continental United States. Gas reserves were estimated at up to 40 trillion cubic feet. That was enough to serve the nation’s entire natural gas demand for 22 months.

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.

During these times of global economic uncertainty, political turmoil and climate change discussions, some, both inside and outside the energy industry, question the value of investing in oil and gas exploration. At the same time, new discoveries, technological advances and collaborative partnerships make exploration more exciting than ever. ExxonMobil Exploration Company President Stephen Greenlee addressed these parallel perspectives during “The Future of Oil and Gas Exploration,” the annual Michel T. Halbouty Lecture he delivered at the AAPG Annual Convention and Exhibition in San Antonio in May.

The shale revolution was made possible because there was technology that allowed developers to drill and complete wells capable of producing oil and gas affordably. Through the years, industry, because of that technology, successfully focused on drilling longer wells, pumping more sand and increasing the number of fracturing stages per well. The question facing industry experts these days is: What will the next breakthrough be that will produce even more efficient and affordable oil and gas?

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.

The title of this month’s column reflects my personal philosophy and framework to address issues that face AAPG. The philosophy embraces AAPG’s Mission by: preserving the past advancements in the science of geology, especially as it relates to petroleum, natural gas, other subsurface fluids, and mineral resources; promoting the present technology of exploring for, finding, and producing these materials in an economically and environmentally sound manner; and fostering the spirit of scientific research throughout its membership to meet the needs of the future.

The application of technology and analytical techniques has always been a hallmark of our profession, but this year ACE had special sessions dedicated to machine learning and AI in petroleum geoscience. The trend toward increased automation and greater efficiency in our workflows will affect how the petroleum explorationist works in the decades to come. Helping our members prepare for this future is something to which AAPG is committed.

Prestack simultaneous impedance inversion was introduced at the turn of this century with the objective of characterization of target rock intervals in terms of elastic properties, which in turn could be associated with petrophysical properties such as porosity, fluid saturation and volume of shale.

As the world heads toward what could be a significant shortfall in energy supply relative to demand, it is more important than ever for our industry to help stakeholders understand the contribution of the hydrocarbon sector in balancing that energy equation. To do that, the industry needs individuals who can find, exploit, and appropriately assess reserves and resources. The AAPG DPA – SPE OGRC Petroleum Reserves and Resources Forum will help decision makers better understand the energy resource picture, and help interpreters and investors make more accurate reserve and resource assessments.
