For decades, reservoir characterization has played a crucial role in oil and gas projects – in identifying and extracting hydrocarbons from the subsurface. Now, some geologists and geophysicists are applying their industry expertise to the emerging fields of carbon storage and geothermal energy.

Initially in charge of funding energy research and resource assessments, Houseknecht received a fateful telephone call in 1995 from former USGS Research Geologist Don Gautier, who asked him to participate in a field session in Alaska. Now, 26 years later, David Houseknecht has been awarded the Wallace E. Pratt Memorial Award for the best AAPG Bulletin article in 2019, which outlines a detailed geological framework of the North Slope to explain the geology of recent discoveries and delineate the potential for future discoveries.

The moment Leslie B. Magoon was told he had won the 2021 Sidney Powers Memorial Award, he was speechless. Presently a senior research geologist with the United States Geological Survey, Magoon simply never considered himself in the running for such a high honor.

AAPG Pacific Section thrilled attendees with a stunning interactive Google Earth-based virtual field trip. Imagine being able to experience the stunning and intricate layered geology of the Monterey Formation through a Google Earth high-resolution, interactive program. Richard Behl, geology professor at California State University at Long Beach, likes to take geologists into the field, walking through the cool surf and sunny climate. At the Pacific Section virtual conference in late June, Behl offered up what he described as a “Monterey Formation Bucket List” of beach outcrop stops traversing more than 500 miles along the California coast from Crystal Cove and up to Bowling Ball Beach near Point Arena. That was only the start of the multiday technical program that was both innovative and technically enriching.

Just as Alaska was bracing itself for the economic fallout of the Biden administration’s adversarial stance on oil and gas, two recent court decisions are giving the state hope. On June 15, a federal judge lifted the administration’s temporary ban on federal lease sales, clearing the way for a highly anticipated lease sale in the prolific National Petroleum Reserve – Alaska. And, on May 26, a brief filed by the U.S. Department of Justice affirmed that the Willow Project, a major discovery in NPRA that has been tied up in environmental-related lawsuits, complies with environmental regulations. While it remains unclear how soon the NPRA lease sale can take place, it is expected that the Willow project, one of the North Slope’s largest projects in recent years, will move forward.

Explorer Historical Highlights

The Los Angeles Times once called William Rintoul “one of the West’s most unusual writers.” Oil field journalists are indeed rare and are becoming even rarer. Nevertheless, their contributions are not to be ignored. Petroleum history is a chronicle of the largest industry that has shaped the modern world for the past 150 years or so. There have been many authors of the history of the oil and gas industry, but William Rintoul was different. It is impossible to decouple California’s petroleum history from Rintoul’s legacy.

Explorer Foundation Update

Thomas E. Hopps was a lifelong Californian who loved geology, loved working the Ventura Basin and other complex state structures and loved, especially, doing what he could to help others. And now that legacy of helping others is about to add a new chapter: A new AAPG Foundation Named Grant-in-Aid is being funded in his name.

Hydraulic fracturing has been around for decades. This talk describes some of the first applications of the technology, how it developed over time, and our current understanding of its impacts with some discussion of both water and earthquake hazards.

VG Abstract

This lecture will discuss the differences between carbonates and siliciclastics from their chemical composition through their distributions in time and space. Building on these fundamental differences, we will explore the challenges carbonates pose to petroleum geologists in terms of seismic interpretation, reservoir quality prediction, field development, etc. Peppered with humorous personal stories, still raging academic debates, and the heartfelt frustrations of real industry professionals, the aim is to inspire students and young professionals to rise to the occasion and embrace the reservoir rocks that petroleum geologists love to hate.

VG Abstract

Microseismicity induced by hydraulic fracture stimulation of a horizontal well was mapped with a near-surface buried array. Distinct linear trends of events were not parallel to the direction of fast shear wave polarization measured in the reservoir with a crossed-dipole anisotropy tool. Analysis of core from a nearby well revealed numerous calcite-filled fractures that did not induce shear wave polarization, but did significantly impact the failure behavior of the reservoir rock during the stimulation treatment. Hydraulic fracture simulation with DFN modeling and source mechanism analysis supports the interpretation of reactivated existing fractures rather than the formation of hydraulically-induced tensile fractures.

VG Abstract

Analysis of microseismicity induced by hydraulic fracture stimulation in the Marcellus Shale shows changes in stress state for different zones of failure. During the treatment, shear failure occurs on both the J1 and J2 fracture orientations in response to different maximum stress orientations, indicating localized changes in the orientation during the treatment. Reactivation of a fault near the wellbore is associated with failure mechanisms with a higher volumetric component, indicating possible inflation of faults and fractures by the introduction of the slurry. Quantification of the stress conditions that are associated with inflation could potentially be used to optimize the stimulation by identifying which fractures will preferentially take on slurry volume.
