“…Induced seismicity in southern Kansas has a Cv between 1 and 8 (Cochran et al, ). In Oklahoma, ~90% of cases in Oklahoma also have a Cv between 1and 8, although areas with HF‐induced seismicity or relatively large (M > 4) magnitude earthquakes have a Cv as large as ~20 (Skoumal, Brudzinski, et al, ). Similar to Skoumal, Brudzinski, et al, (), we group seismicity in 0.1° × 0.1° geographical bins and we determine whether seismicity is predominately induced by WD or HF.…”

We find that the WD and HF earthquakes have a Cv of 2.9 (±2.1) and 9.8 (±1.7), respectively, which are similar to values reported previously in Kansas and Oklahoma (Cochran et al, 2018;Skoumal, Brudzinski, et al, 2019).…”

Induced Seismicity in the Delaware Basin, Texas

The seismicity rate in the Delaware Basin, located in western Texas and southeastern New Mexico, has increased by orders of magnitude within the past~5 years. While no seismicity was reported in the southern Delaware Basin during 1980-2014, 37 earthquakes with M > 3 occurred in this area during 2015-2018. We generated an improved catalog of~37,000 earthquakes in this region during 2009-2018 by applying multistation template matching at both regional and local stations using all earthquakes in the Advanced National Seismic System (ANSS) and TexNet catalogs. We found that the vast majority of the seismicity is most likely associated with wastewater disposal, while at least~5% of the seismicity was induced directly by hydraulic fracturing. We inferred far-field effects of wastewater disposal inducing earthquakes over distances >25 km. The spatial limits of seismicity correlate with geologic structures that include the Central Platform and Grisham Fault, suggesting hydrologic compartmentalization by low-permeability boundaries. Given that the seismicity rate increased throughout the duration of the study, if industry operations continue unaltered, it is likely that both the seismicity rate and number of M > 3 earthquakes may continue to increase in the future.

“…Other measures have also been proposed for the identification of HF‐induced seismicity. In the ΔEQ rate approach, the earthquake rate during stimulation is compared to rates before and after the stimulation (Skoumal, Ries, et al, 2018; Skoumal et al, 2019). This approach provides a simple means to sort wells in a basin based on their degree of seismicity rate change.…”

Hydraulic fracturing (HF) is a technique that is used for extracting petroleum resources from impermeable host rocks. In this process, fluid injected under high pressure causes fractures to propagate. This technique has been transformative for the hydrocarbon industry, unlocking otherwise stranded resources; however, environmental concerns make HF controversial. One concern is HF‐induced seismicity, since fluids driven under high pressure also have the potential to reactivate faults. Controversy has inevitably followed these HF‐induced earthquakes, with economic and human losses from ground shaking at one extreme and moratoriums on resource development at the other. Here, we review the state of knowledge of this category of induced seismicity. We first cover essential background information on HF along with an overview of published induced earthquake cases to date. Expanding on this, we synthesize the common themes and interpret the origin of these commonalities, which include recurrent earthquake swarms, proximity to well bore, rapid response to stimulation, and a paucity of reported cases. Next, we discuss the unanswered questions that naturally arise from these commonalities, leading to potential research themes: consistent recognition of cases, proposed triggering mechanisms, geologically susceptible conditions, identification of operational controls, effective mitigation efforts, and science‐informed regulatory management. HF‐induced seismicity provides a unique opportunity to better understand and manage earthquake rupture processes; overall, understanding HF‐induced earthquakes is important in order to avoid extreme reactions in either direction.

“…ubsurface injection of fluid may induce earthquakes (1) through anthropogenic alteration of crustal stresses (2). In the case of hydraulic fracturing (HF), high-pressure injection of fluid intended to increase the permeability of tight shales has been known to trigger earthquakes (3), some of which are large enough to be recorded or felt regionally (4)(5)(6)(7)(8). Within the Western Canada Sedimentary Basin, the recent increase in seismicity has been largely attributed to HF (9).…”

A sharp increase in the frequency of earthquakes near Fox Creek, Alberta, began in December 2013 in response to hydraulic fracturing. Using a hydraulic fracturing database, we explore relationships between injection parameters and seismicity response. We show that induced earthquakes are associated with completions that used larger injection volumes (10 to 10 cubic meters) and that seismic productivity scales linearly with injection volume. Injection pressure and rate have an insignificant association with seismic response. Further findings suggest that geological factors play a prominent role in seismic productivity, as evidenced by spatial correlations. Together, volume and geological factors account for ~96% of the variability in the induced earthquake rate near Fox Creek. This result is quantified by a seismogenic index-modified frequency-magnitude distribution, providing a framework to forecast induced seismicity.
