Abstract

Increased levels of induced seismicity since 2017 in the Delaware Basin (West Texas and New Mexico, USA) has gained the attention of the geoscience community. Knowledge about seismic attenuation in this sedimentary basin is very limited. We applied the peak frequency method to selected seismic events with high signal-to-noise ratio from the Delaware Basin to estimate effective quality factors representing the basin sediments. The observed attenuation can be characterized by attenuation factors (Q) of ranging between 90 and 100 (with uncertainty of 30) for P-wave and S-waves, respectively. The ratio between QP and QS is common for saturated sedimentary basins as they are less attenuating the S-waves.
