Natural gas industry studies project that United States gas consumption will increase in the early years of this century by up to 50 percent from the current 22 trillion cubic feet to in excess of 33 trillion cubic feet by 2015.

Domestic oil and gas finders are attracted to international turf for any number of reasons -- the lure of the big find, the challenges inherent in uncharted territory. Indeed, it can be a heady experience.

In 1969, Shell Oil began looking for places where its new 'bright spot' technology could be useful in the onshore of the United States. Armed with a list of rock and fluid criteria, I began making a search for places where this novel technique could be as useful to Shell in the onshore USA as it was in the Gulf of Mexico.

One hundred years of petroleum exploration and development in the Los Angeles region have produced a rich legacy of geological and geophysical data -- a legacy that the oil industry has spent billions of dollars to obtain.

While depressed oil prices in the late 1990s cooled data preservation efforts, officials are trying to kick-start a cross discipline approach that would incorporate all earth science disciplines that benefit from the data.

In this computer age it's easy to lose sight of the all-important fact that those gee whiz computer graphics and models that so beautifully depict the subsurface of the earth still have to start with the basics. The geologic data and rocks.

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

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.
