Passive Seismic Interferometry as a Tool for Seismic Imaging from Mine Galleries

83rd EAGE Annual Conference & Exhibition, 2022
To test passive seismic interferometry (PSI) in underground mining environments, we carried out an active-source seismic and continuous noise measurement in a mine gallery of a former radioactive waste repository - the Asse II salt mine (Lower Saxony, Germany).

Uncertainties in passive seismic monitoring

The Leading Edge, 2009
The use of passive seismic techniques to monitor oil- field completion and production processes is on the rise. Stress changes induced by such reservoir activities as hydraulic fracturing, water injection, or fluid extraction will often result in failure of the rocks with a concurrent release of seismic energy in the form of compressional (P) and shear

Passive seismic measurement of seismic attenuation in Delaware Basin

The Leading Edge, 2019
Abstract Local earthquake activity can be employed to measure attenuation (the effective quality factor [Q]) and characterize production in the Delaware Basin, Texas, USA. To illustrate this, we employed data from the recently installed Texas Seismic Network (TexNet) seismic stations collected in the west Texas area between April 2017

Calibrating borehole seismic attributes with passive seismic data

SEG Technical Program Expanded Abstracts 2003, 2003
In this paper we describe a number of fundamental seismic attributes that can be determined from passive seismic borehole recordings. Passive data can be used to determine not only direct images of reservoir fracturing, but also background borehole noise characteristics, velocity model details including lateral variations and anisotropic ...

Imaging passive seismic data

Geophysics, 2006
Abstract Imaging passive seismic data is the process of synthesizing the wealth of subsurface information available from reflection seismic experiments by recording ambient sound using an array of geophones distributed at the surface.

Surface Passive Seismic in Kuwait

First EAGE Passive Seismic Workshop - Exploration and Monitoring Applications, 2006
Surface passive seismic is a direct hydrocarbon saturation indicator technique. It detects the presence of subsurface hydrocarbons by recording and spectroscopically analyzing the low-frequency acoustic/seismic background noise (between 0.5- 10 Hz) which is actively emitted by the earth.

Passive seismic imaging using microearthquakes

Geophysics, 1995
Abstract We have developed a method of processing seismic signals generated by microearthquakes to image local subsurface structure beneath a recording station. This technique uses the autocorrelation of the vertically traveling earthquake signals to generate pseudoreflection seismograms that can be interpreted for subsurface ...
