Winston Churchill said, “The farther backward you can look, the farther forward you can see.” For me, during the past seven years this has been a wonderful ride with many milestones along the way. I thank all of the members and staff for your hard work and support.

AAPG has several opportunities in the next several weeks for those who want to make vacation time last a little longer by taking a field seminar. There also are short courses to help you brush up on much-needed skills (and earn Professional Development Hours, too).

Like Estragon and Vladimir, who are waiting for the inevitable in Waiting for Godot, geologists, too, are waiting for an earthquake to come to Los Angeles and its surrounding communities. And like the two protagonists in Beckett’s masterpiece, they also don’t know when it will come, where it will appear or the extent of its impact.

A joint effort by the Energy Minerals Division and the Division of Environmental Geosciences has been undertaken to compile peer-reviewed contributions of research and applications of geological sequestration of CO₂ being performed in the petroleum, energy minerals, and environmental fields into an AAPG special publication.

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

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

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.
