Fluid-injection induced seismicity in the Cooper Basin (Australia): spatial, temporal, and energy characteristics
نویسندگان
چکیده
Induced seismicity has been recognized as a concern in subsurface industrial operation, and particularly at fluid-injection sites in major oil and gas exploitation plays, where hydraulic stimulations are conducted to increase rock permeability. Induced seismicity occurs also in Enhanced Geothermal Systems (EGS), where hydraulic fracturing is used to accelerate heat extraction from the rock. If that seismicity can be controlled, EGS may represent a valid alternative to produce energy with a low-carbon impact.

A century of oil-field operations and earthquakes in the greater Los Angeles Basin, southern California
Most of the seismicity in the Los Angeles Basin (LA Basin) occurs at depth below the sediments and is caused by transpressional tectonics related to the big bend in the San Andreas fault. However, some of the seismicity could be associated with fluid extraction or injection in oil fields that have been in production for almost a century and cover ~ 17% of the basin. In a recent study, first the...
متن کاملInvestigation of possible induced seismicity due to wastewater disposal in the Delaware Basin, Dagger Draw Field, New Mexico-Texas, USA
Since the 1960s, numerous cases of induced seismicity have been associated with reservoir impoundment, mining and the injection of fluids into the subsurface [National Resources Council, 2012]. In recent years, fluid injection activities have intensified as a result of growing shale gas production, enhanced oil recovery, disposal of produced waters in dedicated injection wells, enhanced geother...
متن کاملFluid-induced Seismicity
The characterization of fluid-transport properties of rocks is one of the most important, yet difficult, challenges of reservoir geophysics, but is essential for optimal development of hydrocarbon and geothermal reservoirs. Production of shale oil, shale gas, heavy oil and geothermal energy, as well as carbon-dioxide sequestration, are relatively recent developments where borehole fluid injecti...
متن کاملAn investigation of seismicity clustered near the Cordel Field, west central Alberta, and its relation to a nearby disposal well
Historically, seismicity documented in the Western Canada Sedimentary Basin has been relatively quiescent and earthquakes are usually restricted to the foreland belt of the Rocky Mountains. However, exceptional clusters of events, which have remained active for decades, are recognized in Alberta. In this study we investigate the seismicity in this region using data obtained from recently establ...
متن کاملSelecting ground - motion models developed for induced seismicity in geothermal areas
2 Summary 20 We present a case study of the ranking and weighting of ground-motion prediction equations (GMPE) 21 for seismic hazard assessment of Enhanced Geothermal Systems (EGSs). The study region is Cooper 22 Basin (Australia), where a hot-fractured-rock project was established in 2002. We test the applicability 23 of 36 GMPEs based on stochastic simulations previously proposed for use at E...
