Hydraulic fracturing-induced seismicity characterization through coupled modeling of stress and fracture-fault systems

چکیده
This work summarizes our recent findings on hydraulic fracturing-induced seismicity nucleated in the Duvernay shale reservoirs within Western Canada Sedimentary Basin. A coupled model of in-situ stress and fracture-fault systems was built to quantify four-dimensional pressure changes spatiotemporal nucleation during fracturing. Five triggering mechanisms were successfully recognized seismicity-frequent areas, including a direct connection between impermeable faults fractures, fault slip owing downward diffusion, reactivation due upward poroelastic perturbation, aftershocks mainshock events, natural fractures surrounding faults. shed light how fracturing operations triggered induced seismicity, providing solid foundation for investigation controlling factors mitigation strategies seismicity.

Discrete Element Simulation of Hydraulic Fracturing and Induced Seismicity in Engineered Geothermal Systems
In this paper the Discrete Element Model (DEM) ‘ESyS_Particle’, previously used to model fracture of brittle rocks and earthquake processes, is further developed to be able to be applied to the hydraulic fracturing process in Engineered Geothermal Systems (EGS). The advantage of DEM is that large deformations and dynamic process can be modelled easily. ESyS_Particle has been used to successfull...
متن کاملHydraulic Fracturing and Seismicity in the Western Canada Sedimentary Basin
The development of most unconventional oil and gas resources relies upon subsurface injection of very large volumes of fluids, which can induce earthquakes by activating slip on a nearby fault. During the last 5 years, accelerated oilfield fluid injection has led to a sharp increase in the rate of earthquakes in some parts of North America. In the central United States, most induced seismicity ...
متن کاملMyths and Facts on Wastewater Injection, Hydraulic Fracturing, Enhanced Oil Recovery, and Induced Seismicity
The central United States has undergone a dramatic increase in seismicity over the past 6 years (Fig. 1), rising from an average of 24M ≥3 earthquakes per year in the years 1973–2008 to an average of 193M ≥3 earthquakes in 2009–2014, with 688 occurring in 2014 alone. Multiple damaging earthquakes have occurred during this increase including the 2011M 5.6 Prague, Oklahoma, earthquake; the 2011 M...
متن کاملHydraulic Fracturing Simulation for Fracture Networks
The term ‘Unconventional Reservoirs’ is used in the oil and gas industry for hydrocarbon reservoirs that have very low permeability in the magnitude of microdarcy (μd) and therefore rely on artificially introducing pathways for fluids and gases, commonly by using hydraulic fracturing techniques, to enable economic production. This approach of using fracturing stimulation campaigns is also incre...
متن کاملLocation of Microearthquakes Induced by Hydraulic Fracturing
This paper examines the problem of locating microearthquakes induced by hydraulic fracturing using seismic arrival time data. In addition to the use of absolute arrival times measured for individual events, we consider the use of differential arrival times amongst a set of two or more seismic events as a means of constralning their locations relative to one another. Differential arrival times c...
