New Insights into Subsurface Exploration and Production
Imagine being able to lower a camera into the subsurface of the earth and record a continuous animation that captures the surroundings in all directions and all angles. Paradigm’s new full-azimuth angle domain imaging and analysis system, EarthStudy 360®, is able to emulate this capability by combining a rich bottom-up ray tracing procedure with the fully recorded seismic wavefield.
EarthStudy 360 is designed to deliver to both depth imaging and processing experts and interpretation specialists a complete set of data that enable them to obtain accurate subsurface velocity models, structural attributes, medium properties, and reservoir characteristics. The system extracts unprecedented value from all modern and legacy seismic data acquisitions, especially those with wide and rich azimuth and long offset, in both marine and land environments, including unconventional shale plays. EarthStudy 360 is not an improved version of existing imaging and interpretation systems; nor is it an evolution of any seismic imaging or interpretation technology in use today. Rather, it is a brand new invention designed to image, characterize, visualize and interpret the total seismic wavefield, and provide previously unattainable levels of subsurface knowledge.
|EarthStudy 360 has successfully undergone full-scale studies and field trials in a number of geological and structural environments. The rich information from all angles and azimuths significantly reduces uncertainty and ensures more reliable analysis. It is a major step towards a full seismic data analysis system with rich deliverables and extremely high levels of user interaction and QC at any state in the workflow.
EarthStudy 360 maximizes the information that can be extracted from recorded seismic data. The system creates a wealth of seismic image data, decomposed into full-azimuth angle-dependent reflectivities and directional (dip and azimuth) data components that can be selectively sampled, creatively combined, dynamically visualized, and further processed to secure images of the subsurface. These images can reveal the information needed for velocity model determination, and provide details regarding the presence of micro-fractures, the orientation of faults and fractures, the influence of anisotropy, the directions of contributing illumination, the elastic properties of target reservoirs, and the boundaries of those reservoirs.
