Pacific Section

Our present activities at the Section level are widespread. We are attempting to increase the number of universities that are affiliated with the AAPG. The California State University at Northridge recently started a student chapter under the guidance of Dr. Kathleen Marsaglia.

AAPG, DPA Oppose Board Move

In late September, the Division of Professional Affairs, through past president Rick Ericksen, was contacted by the California Association of Professional Geologists (CAPG), which is seeking support to block a move by the state of California to eliminate the Board of Professional Geologists and Geophysicists (BGG) and merge it into the Board of Professional Engineers and Land Surveyors (BPELS).

From Old Stripper to Power Producer

Thinking outside the box: One surprise at the recent summer NAPE was a linear driver free-piston engine that can turn watered-out wells into long-life electrical power producers.

A Brief History of Hydraulic Fracturing and Induced Seismicity

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.

Induced Hydraulic Fractures or Reactivated Natural Fractures?

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.

Confounding Carbonates: The Reservoir Rocks that Won't Play Nice

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 By Sherilyn Williams-Stroud

Fracture Mechanics Interpreted from Stress Inversion Analysis on Microseismic Event Source Mechanisms in the Marcellus Shale

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.
