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.

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.

The environment is in your face this year. Here in Los Angeles, we had one of the clearest springs that I can remember. All because the COVID-19 virus resulted in a huge shutdown of most everything that took us outdoors. Come summer and the fires struck the western states. The air turned brown and the visibility went to nearly zero. It stayed that way all the way to summer’s end. This was a huge wakeup call on how sensitive the atmosphere is to changes brought about by aerosols. This brings to mind a story about the biggest tourist attraction in the greater Los Angeles area in the late 19th and early 20th century.

Welcome to a new series in the AAPG Learn! Blog entitled “My Favorite Outcrop.” In this series, we chat with geoscientists who tell us about their favorite outcrops encountered during their work in the field. Today we meet with Clara Abu, who is one of the founding members of the Salt Basins Technical Interest Group. One of her favorite outcrops was in Tusher Canyon, Utah, featured in the photo.

Call it unprecedented, call it exciting and unpredictable, call it historic – and you’re right each time. The 2020 Imperial Barrel Award global finals competition was one for the record books – for the first time ever, the entire competition, impacted by the global pandemic that threatened to end it before it began, was held virtually in early June, adding a new chapter in the program’s illustrious history. Indeed, this year’s competition had many firsts – a global pandemic, an entirely virtual competition and the introduction of the IBA Exploration Leadership Series.

The DEG leadership unanimously endorsed EnergySource Minerals in San Diego to receive a DEG Corporate Award for their efforts to harness for lithium extraction the brine flow supplying the John L. Featherstone geothermal power plant in the Salton Sea region. EnergySource Chief Operating Officer Derek Benson shared with us that a proprietary process called “Integrated Lithium Adsorption Desorption,” or “ILiAD,” was demonstrated to be the key that unlocks Salton Sea lithium development. They have succeeded in producing battery-grade lithium carbonate and lithium hydroxide utilizing the brine flow as it exits the power generation.

Assistant Professor of Geological Science (Tenure Track) CSU Long Beach

The Department of Geological Sciences, California State University Long Beach (CSULB) invites applications for a tenure-track Assistant Professor in Geophysics or in any other Geoscience discipline that substantially employs geophysical methods in research to start Fall 2022. A qualified candidate should be dedicated to teaching at the undergraduate and Masters level and committed to developing an externally funded research program that will involve students.

VG Abstract

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

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.
