In the summer of 1865, Thomas Bard arrived in Ventura County, Calif., to begin exploration drilling on properties owned by his uncle, Thomas Scott, in the area of Sulphur Mountain. Scott had made a fortune investing in Pennsylvania railroads in the 1850s and in Titusville oil fields in the early 1860s. Scott undertook petroleum exploration in California on the basis of sensational reports of the oil potential there published by Yale professor Benjamin Silliman in 1864. Writing to Scott about the Sulphur Mountain area, Silliman said, 'Its great value is in its almost fabulous wealth in the best of oil.'

When asked what they know about Livermore, Calif., most people think of the nuclear weapons laboratory with the largest lasers and computers, and some think of the oldest wine region in the state, but no one thinks of it as an oil producing region. Yet Livermore was the site of one of the earliest oil wells in California and still has a small, declining oil field just east of Lawrence Livermore National Laboratory.

Laura Branch teaches high school science courses and is one of only a few credentialed Earth science teachers in Santa Barbara County and has the only upper-level high school geology class in the county. As a geoscience instructor, Branch is able to teach her students about the petroleum system and the seepage of oil and heavy oil in the coastal area.

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.
