A method and system of processing seismic data includes acquiring three-component seismic data and combining horizontal components of the three-component seismic data to obtain a merged horizontal component. Frequency spectra are determined for the acquired three-component seismic data. A ratio of a vertical component of the seismic data to the merged horizontal component is determined. A V/H integration-measure is obtained from the integration of the area bounded by a selected minimum-amplitude value and the amplitude values greater than the selected minimum-amplitude value and the V/H integration-measure is stored in a form for display.

A method and system of detecting and mapping a subsurface hydrocarbon reservoir includes determining ratio data for a plurality of orthogonal spectral components of naturally occurring low frequency background seismic data. The ratio data may be compared, plotted, contoured and displayed as a subsurface hydrocarbon reservoir map or a hydrocarbon potential map. The ratio data may represent a vertical spectral component of the seismic data over a horizontal spectral component of the seismic data. The subsurface hydrocarbon reservoir map may include contouring the ratio data over a geographical area associated with the seismic data.

A method and system for processing synchronous array seismic data includes acquiring synchronous passive seismic data from a plurality of sensors to obtain synchronized array measurements. A reverse-time data propagation process is applied to the synchronized array measurements to obtain a plurality of dynamic particle parameters associated with subsurface locations. Imaging conditions are applied to obtain imaging values that may be summed or stacked to obtain a time reverse image attribute. A volume of imaging values may be scaled by a non-signal noise function to obtain a modified image that is compensated for noise effects.

A reverse-time data process is applied to the synchronized array measurements to obtain a plurality of dynamic particle parameters associated with subsurface locations. These dynamic particle parameters are stored in a form for display. Maximum values of the dynamic particle parameters may be interpreted as reservoir locations. The dynamic particle parameters may be particle displacement values, particle velocity values, particle acceleration values or particle pressure values. The sensors may be three-component sensors. Zero-phase frequency filtering of different ranges of interest may be applied. The data may be resampled to facilitate efficient data processing.

Storing CO2 in the subsurface to reduce global warming, finding hydrocarbon and other resources and monitoring their extraction, generating energy with Earths internal heat, and forecasting natural hazards (earthquake-induced ground motion, volcanic eruptions) requires high-resolution tomographic images of the Earths interior. The main goal of QUEST is research and training in the development of strategies for automated seismic imaging using the increasing power of 3-D simulation technology. While so far the observed information was severely reduced to determine Earths structure, the massive increase in available computational resources allows us now to make use of the complete information contained in the observations. With narrowing resources and increasing energy prizes the exploration industry is seeking highly skilled young scientists capable of driving the new computational technologies towards industrial problems. Earth Science graduating students are lacking profound theoretical and practical training in numerical methods and high-performance computing. QUEST intends to fill this gap offering the students excellent prospects in industry and academia as the combination of skills to be trained are highly in demand. We also expect substantial progress in understanding the dynamics of our planet, the quantification of natural hazards such as earthquakes, tsunamis, and volcanic eruptions. QUEST will link world-leading scientists in methodologies such as computational wave propagation, the theory of inverse problems and global tomography with two of the best industrial research laboratories in geophysics and computing world wide. QUEST will have a lasting impact on the practice of seismic tomography, leading to High-Performance-Computing solutions applicable to industrial and academic challenges, and a generation of young researchers capable of producing better Earth images that help us tackle the challenges of future energy-resource management and natural-hazard related research.
