Alliance Geotechnical Services staff bring over 20 years experience in land, marine, shallow water and transition zone seismic data analysis and processing services to Southeast Asia.
AGS has both the tools and experience to solve a wide range of imaging objectives, such as thrust fault, sub-salt and rugged terrain imaging, and accommodate a variety of imaging acquisitions, including wide angle, OBC and other multi-component recordings.
Using industry leading seismic processing and imaging technology including Paradigm's Echos and GeoDepth software as well as GMG and FusionGeo software, and Ikon’s RockDoc, Alliance Geotechnical Services can provide the highest level of quality, consistency, and cost effectiveness to our clientele.
2D/3D Prestack and Postack Time and Depth Imaging
AGS offers a full range of 3D pre-stack and post-stack time and depth migration methods, with supporting velocity model building technology from the industry-leading Paradigm GeoDepth velocity model building and depth imaging system.
Kirchhoff migration is the most commonly used migration for depth processing. It is particularly attractive due to its speed and target-oriented capability, which enables efficient velocity model building and updating. In addition, the Kirchhoff migration offers adaptability to irregular acquisition geometries, and flexibility in handling anisotropic and converted wave velocity models.
Phase Shift Migration.
Incorporates the full aperture, providing operational advantages over Kirchhoff migrations when performing full volume imaging and generally produce images with less background or operator noise than those created with Kirchhoff migrations.
Reverse Time Migration (RTM).
Solution for imaging seismic data in areas of complex wave phenomena. It is able to handle the most severe combinations of structural dip with high velocity contrast, conditions common in salt basins and other geologic basins with complex structures and velocity distributions.
Common Angle Reflection Migration (CRAM).
A cluster-based imaging system that generates conventional reflection angle gathers without azimuth dependency. These gathers can be used in standard interpretation systems for accurate velocity model building and amplitude inversion.
Full Azimuth Imaging (ES 360).
AAn imaging system that maximizes the information that can be extracted from recorded seismic data. The system creates 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.
AVO / Inversion
Using Paradigm’s Probe technology, AGS combines data, knowledge and technology, including amplitude preserving pre-processing, multi-well/multi-attribute seismic-to-well calibration, AVO inversion, elastic modelling, petrophysics and 3D interpretation, in one comprehensive system. Probe supports both conventional AVO and multi-azimuth, anisotropic AVAZ workflows.
The Paradigm Vanguard seismic reservoir characterization system is a comprehensive, multi-attribute platform that integrates seismic, well and geological data to produce a description of reservoir properties including impedances, porosities, saturations and lithology.
