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.

Perception vs. reality: Any opinions that the energy industry is old school are definitely old hat – high-tech advances are being encouraged and embraced by 21st century geoscientists.

Welcome to the 2011-12 series of short EXPLORER articles by the Division of Environmental Geosciences. As the new president of DEG, I get to kick off the series with my view of one of the technical areas that DEG – and AAPG in general – needs to address this fiscal year.

It is approximately 80 miles between Titusville, Pa., and Fredonia, N.Y. – and while nobody is suggesting the rivalry between these two cities is on par with, say, the competition between the Red Sox and the Yankees, the origins of the petroleum industry is becoming a bone (a well?) of contention.

There may be many reasons for the success geoscientists recently reported at Salt Creek, Wyoming – but a big one was the result of data collected from a 4-D seismic survey, which revealed fine interval resolution as well as identified flow patterns that cannot be seen from well data alone.

Workshop
Virtual Workshop
Tuesday, 8 March Wednesday, 9 March 2022, 8:00 a.m.–5:00 p.m.

This two-day virtual conference aims to bring together industrial and academic persons to present, explore and develop approaches that will benefit both sectors in the future. The virtual conference will focus on current techniques, the challenges and future solutions in understanding the Triassic stratigraphy of the North Sea, Norwegian Sea, West of Shetland, Atlantic margins, and northern Europe.

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.

This is a less-technical education topic. It can be condensed to an hour or given as 2 two-hour sessions. It stresses selected controversial aspects of fracking that touch some combination of environment and economics and includes a short video of how fracking is done.

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.
