Breaking the seismic 4D ‘image’ paradigm of seismic monitoring
First Break, 2021Abstract Seismic imaging techniques were designed for exploration. To better image the subsurface, the industry developed high-resolution 3D seismic monitoring methods which used systems able to record hundreds of thousands of channels simultaneously.

Unconventionals in Seismic Monitoring
Proceedings, 2012Passive seismic monitoring gives essential information on reservoir dynamics, cap-rock integrity, propagation and extend of fracking activities, and eventual hazard scenarios by potential triggering of induced seismicity. Data analysis can either be performed by classical, seismological tools for determination of single-event properties like hypocenter,

Monitoring Seismic Processing For Seismic Reservoir Characterization
International Petroleum Technology Conference, 2009This reference is for an abstract only. A full paper was not submitted for this conference. Abstract Seismic reservoir characterization (for instance, inversion) requires a well-controlled seismic signal that can sometimes not be guaranteed by conventional processing QCs. One option is to use borehole

Seismic Characterization of Landslides and the Emergence of Seismic Monitoring
Proceedings, 2012After a short introduction on the main problems that need to be better understood in order to better model landslide dynamics, this contribution focuses on how geophysical methods and in particular seismic methods can help in better characterizing the geometry and heterogeneities of landslides.

Global Seismic Monitoring: A Bayesian Approach
Proceedings of the AAAI Conference on Artificial Intelligence, 2011The automated processing of multiple seismic signals to detect and localize seismic events is a central tool in both geophysics and nuclear treaty verification. This paper reports on a project, begun in 2009, to reformulate this problem in a Bayesian framework.

Seismic and gas monitoring of volcanic sites
2015 IEEE Sensors Applications Symposium (SAS), 2015Geophysical and geochemical monitoring of volcanic areas have a notable impact for the assessment of the geological instability and for safety of the populations. Nowadays the low cost Micro Electro-Mechanical Systems (MEMS) devices and Wireless Sensor Networks (WSNs) could represent a good way to perform a real-time monitoring task.

Monitoring Creep Movements by Seismic Refraction
1st EEGS Meeting, 1995The Italian Apenninic area is a well known example of hydrogeological and landslide hazard, due to recent largely incoherent shallow formations like clay, sandstone, flysch. When artifacts must be built as roads, bridges, dams..., a very careful study of buried geology and lithological properties must be performed in advance, resorting to intensive ...

Weyburn Field Seismic Monitoring Project
67th EAGE Conference & Exhibition, 2004High-resolution, time-lapse (4-D), multicomponent (9-C) seismic data acquired by the Reservoir Characterization Project (RCP) of the Colorado School of Mines were used to monitor a miscible CO2 flood in a thin (30m) carbonate reservoir at a depth of 1450m in Weyburn field, Saskatchewan.

1997
Seismic sensors are distributed around or throughout the volume of interest. The monitoring system must accurately record the amplitude and timing of any significant ground motion over a wide range of amplitudes, frequencies and durations, and assemble the records at a central point for processing, within a reasonably short time so that action may be ...

Seismic monitoring of hydrocarbon fluid flow
Journal of Mathematical Imaging and Vision, 1995Time-lapse 3-D seismic monitoring of subsurface rock property changes incurred during reservoir fluid-flow processes is an emerging new diagnostic technology for optimizing hydrocarbon production. I discuss the physical theory relevant for three-phase fluid flow in a producing oil reservoir, and rock physics transformations of fluid-flow pressure ...
