The world’s best classroom? The beautiful and dramatic outcrops that dominate the western Ireland’s Clare and Kerry counties have provided enormous value as analogs to thousands of geoscientists – and new lessons are still being learned there.

It’s a green energy world we currently live and work in, and regardless of the merits of coal, uranium, geothermal, gas shales – and the list goes on – what we have learned over the years, and notably over the past few years, is that environmental concerns can determine, more often than not, whether our profession and industry is successful or not.

Texas Gov. Rick Perry gave his State of the State address Feb. 8, with the central theme being “Reform and the Streamlining of State Government.” As with many states, Texas is facing red ink. The governor wants to balance the budget, and in order to do so one of his initiatives is to combine or suspend 40 boards.

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).

Well, shake it up, baby: Hydro-impact technology is using seismic wave stimulation technology to shake loose residual oil trapped in the reservoirs around existing wells.

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.

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.
