I have had the privilege of serving as one of the AAPG Women’s Network co-chairs since 2020 and it has been a pleasure to watch the network grow over these last two years. In that time, our membership has grown from fewer than 100 to nearly 800 members. This growth can be attributed to the numerous opportunities our team has developed for the AAPG community, including technical training, career development, mentoring, networking and much more.

Here’s one sign of change in university- level geoscience education: This year, for the first time, both recipients of AAPG’s Grover E. Murray Memorial Distinguished Educator Award are female geology professors. Their careers have followed different paths and include contrasting professional interests, but the stories of their respective educational histories share several common links. That story starts with James Taylor. And chocolate chip cookies.

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.

Elastic anisotropy, widely recognized as a typical feature of sedimentary formations, has a strong influence on seismic velocities and amplitudes. For example, the difference between stacking and vertical velocity in anisotropic media most commonly is the reason for misties in time-to-depth conversion. This course provides the necessary background information regarding anisotropic wave propagation and discusses modeling, inversion, and processing of seismic reflection data in the presence of anisotropy.

Wednesday, 8 June 2022, 8:00 a.m.–9:00 a.m.

Join the Petroleum Systems Technical Interest Group (TIG) for the next session of the AAPG Petroleum Systems Webinar Series, "Using Geochemistry to Understand Production GOR in Unconventional Reservoirs", on Wednesday, 8 June 2022, 8:00 AM (CST). A common question in appraisal or development of either conventional or unconventional reservoirs is understanding the control on production yield (stb/mmscf) or GOR (stb/scf).  Fluid and/or rock-based geochemistry is a useful tool in conjunction with engineering principles to understand what the primary mechanism(s) are controlling production yield.  Here we will look at the use of geochemistry to access yield for tight reservoirs.

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.
