High frequency (8-15 KHz) seismic waves that travel between two boreholes are used to probe the detailed structure of rock in the Los Alamos Scientific Labora:ory Fenton Hill geothermal energy reservoir. Because of the unique ability to control fluid pressure in the reservoir, we can make in situ seismic measurements at different fluid pressures and apply the results of pertinent laboratory mea...

This paper broadly highlights the issues and concerns faced in the Oil & Gas industry today, while deploying and managing such a collection of products and tools for various E&P applications at the enterprise level. The E&P scope encompasses the applications in the domain of Seismic Acquisition and Processing, Surface Interpretation, Reservoir Simulation, Petrophysics, Characterization & Visual...

Subsurface modeling from seismic and borehole data is important for reservoir prediction, geophysical exploration, and production. A reasonable model should honor borehole rock properties and conform to seismic structural and stratigraphic features. Such a subsurface model can be difficult to build in cases complicated by faults and unconformities. Automatic and semiautomatic methods have been ...

This work focuses on the seismic response of a volcano to different magmatic processes with the aim of sheding light on their driving physics as tracked by seismicity. We study seismic time series recorded at basaltic volcanoes and identify generic seismicity patterns characteristic of (i) inter-eruptive, (ii) reservoir feeding, (iii) reservoir leak, and (iv) dyke injection phases of volcanic a...

Coherency cube” and fault detection technologies have evolved rapidly in recent years as important tools for seismic interpretation. The following paper, developed as a joint project between investigators at Memorial University and the University of Calgary, compares several of the fault detection methods for data from Hibernia field. The results, which are outlined in detail in the Memorial Un...

Geological carbon sequestration involves large-scale injection of carbon dioxide into underground geologic formations and is considered as a potential approach for mitigating global warming. Changes in reservoir properties resulting from the CO2 injection and migration can be characterized using waveform inversions of time-lapse seismic data. The conventional approach for analysis using wavefor...

The attenuation values obtained in the lab are usually larger than those measured in the field. To understand this inconsistency, I propose to model attenuation from rock properties and reflection seismic data, and then compare their results. A gas well is used here for providing the rock properties and seismic properties. The preliminary results show that scaling is one of the factors that low...

To extract all the oil from a well, petroleum engineers pump hot reactive chemicals into the well. These Enhanced Oil Recovery (EOR) processes need to be thoroughly monitored, since the injected fluids can seep out of the production oil wells and, if unchecked, eventually pollute sources of drinking water. There is a need to measure the corresponding effects. One way to measure these undergroun...

Seismic data acquired in the field show subsurface reflectors or horizon among geological strata, while seismic inversion converts this reflector information into acoustic impedance section which shows layer properties based on lithology. The research aims to predict porosity identify reservoir is between tight layer. So, output of much more batter than as it closer reality such geology. freque...
