If you could listen to a heartbeat of the geophysical industry today, you might be tempted to call 911. While not yet to the life support stage, the health of this sector might best be described as poor and still declining.

Regulations regarding seismic exploration on federal land — an important factor in any program, but especially in the U.S. West, where so much of the land is federal acreage — are causing companies and crews to rethink their operations.

Borehole seismic methods have been used since the beginning of exploration seismology. Check shot surveys were used to obtain travel times and interval velocities, and 2-D VSPs (Vertical Seismic Profiles) and 2-D high-resolution crosswell data also have been recorded.

The proposed Lease Sale 181 in the eastern Gulf of Mexico -- the area's first since 1988 -- is facing a big political showdown that goes all the way to the Oval Office.

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.

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.
