SHALLOW & DEEP WATER SOLUTIONS

Deploying the latest OBN technology, SAExploration is capable of acquiring and processing 2D, 3D and 4D full azimuth and full wavefield seismic datasets, with either single (1C) or two-component (2C) or four-component (4C) sensing technology, in water depths from 0 to 3,000 meters.

SAExploration maintains a steadfast commitment to maximizing the quality of seismic processing for complex geology, irregular and sparse survey geometries. Our depth processing and imaging program contains multiple modules and applications for deconvolution, wave-equation migration, model building, de-multiple and post-migration processes.


Specializing in Wavefield Modeling and Wave-Equation Depth Imaging, SAExploration delvers three migrated volumes of data: up-coming field, down-going field and the sum of direct and mirror migrations. We also offer converted-wave imaging (isotropic & anisotropic), where the Common-Conversion-Point (CCP) binning technique is not required.


From advanced 2D, 3D and 4D surveys, to multi-component design. SAExploration’s processes and technologies are designed to affordably, efficiently and accurately meet project objectives.


Seismic Processing Technology

SAE has developed a depth imaging technique based on wave-equation migration to handle acquisitions with sparse receivers as well as a proper accommodation of lateral velocity variation in complex geologies. Our proprietary software is designed to meet the demands of the industry providing efficient, consistent and reliable high quality imaging solutions.


Depth Imaging

We are committed to maximize the quality of seismic processing for complex geology, irregular and sparse survey geometries. The depth processing and imaging capability has an extensive number of modules and applications for deconvolution, wave-equation migration, model building, wave-equation multiple attenuation and post-migration processes.


Wavefield Separation

SAE’s wavefield separation algorithm obtains an accurate matching filter to adjust the vertical geophone component to the hydrophone. The matched data is QC’d, co-sensor summed and co-sensor differenced to separate up-coming and down-going wave, essentially doubling the fold of the survey.


3D Pre-Stack PSPI Migration

SAE’s 3D PSPI migration module provides an accurate, efficient and affordable solution to seismic imaging based on wavefield extrapolation. As the geology gets more complicated, less confidence is placed in ray tracing based techniques such as Kirchhoff Migration.


C-Wave Processing

SAE offers 2D and 3D converted-wave solutions for isotropic and anisotropic imaging. Our algorithms use P velocity for down-going waves and S velocity for up-coming waves. Our depth focusing converted-wave velocity analysis application is used to determine S velocity model.


Depth Focusing Velocity Analysis

SAExploration’s depth focusing converted-wave velocity analysis is an iterative application based on determining the best imaging velocity by examining how the energy is “focused” during the wave-equation migration. With this process, tomography techniques are not necessary.


3D Wave-Equation Multiple Attenuation

One of a few multiple suppression techniques, 3D wave-equation multiple attenuation especially well adapted to 3D common receiver data (ocean bottom node). Using this process, predicted multiples are suppressed by least squares adaptive subtraction process.
