Unconventional Gas Development

Background: This study explores sociodemographic disparities in residential proximity to unconventional gas development (UGD) among pregnant women. Methods: We conducted a secondary analysis using data from a retrospective birth cohort of 164,658 women with a live birth or fetal death from November 2010 to 2012 in the 24-county area comprising the Barnett Shale play, in North Texas. We considered both individual- and census tract-level indicators of sociodemographic status and computed Indexes of Concentration at the Extremes (ICE) to quantify relative neighborhood-level privilege/disadvantage. We used negative binomial regression to investigate the relation between these variables and the count of active UGD wells within 0.8 km of the home during gestation. We calculated count ratios (CR) and 95% confidence intervals (CI) to describe associations. Results: There were fewer wells located near homes of women of color living in low-income areas compared to non-Hispanic white women living in more privileged neighborhoods (ICE race/ethnicity + income: CR = 0.51, 95% CI = 0.48–0.55). Conclusions: While these results highlight a potential disparity in residential proximity to UGD in the Barnett Shale, they do not provide evidence of an environmental justice (EJ) issue nor negate findings of environmental injustice in other regions.

Microseismic Event

Hydraulic fractures are delineated by induced microseismic event distributions and typically propagate perpendicular to the regional minimum stress direction. However, at a smaller scale, varying mineralogical composition and existing fault and fracture networks can influence developing fracture networks. We integrated microseismic event locations with seismic attributes from multichannel seismic reflection data, including inversion results for impedance and Lamé parameters, and seismic curvature attributes. We found that microseismic event locations consistently correlate to zones of low seismic impedance and low [Formula: see text] and [Formula: see text] values, describing characteristic material properties of fracture-prone zones within the North Texas Lower and Upper Barnett Shale. Additionally, event locations showed a weak correlation with anticlinal structures as defined by volumetric curvature attributes. We suggest that the low impedance, low [Formula: see text] and [Formula: see text] zones were related to the boundary between calcite-filled fractures and the host rock.
