An Analysis of Focal Parameters with Application to West Texas Micro-Earthquakes
Two types of seismic events related to hydrocarbon production have been extensively studied recently: microseismic events associated with hydraulic fracturing in unconventional reservoirs and induced seismicity associated with fluid extraction and wastewater injection in oil fields. This …

Challenges of geophysical processes and interpretation of an unconventional play: a case study from Wattenberg field, Denver-Julesburg Basin, Colorado, The
Unconventional production formations are frequently complex to characterize, due to what could be interpreted as sudden lateral stratigraphic changes, potential stress variations, and the inability to use Gassmann's Fluid Substitution theory directly. While general trends of limited permeability, …
