Attention to detail and a customer-centric approach is what sets us apart. Our unique geology-driven approach integrates well log data into the processing sequence ensuring our seismic volumes are fully calibrated to geology – shortening cycle time by producing interpretation-ready data. With our extensive processing toolkit, we deliver a suite of seismic attributes for reservoir characterization. And, while we are known as the imaging experts onshore we also have advanced tools and leading experts in offshore and OBC environments.
We tackle the toughest seismic imaging challenges.
In 20 years of operations and countless 3-D seismic processing projects worldwide, we are the experts in imaging onshore, offshore, OBC, hard rock geology, and conventional and unconventional plays.
AZIM: Azimuthal Velocity Variations
Our patented AZIM technology is the industry’s leading method to measure azimuthal velocity variations. It is used to detect reservoir fracture patterns and to improve quantitative AVO (amplitude variation with offset). Using AZIM technology, our clients have successfully optimized production from heterogeneous, tight reservoirs around the world. By characterizing azimuthal anisotropy accurately, AZIM provides several key benefits:
Produces a high-density, azimuthally-varying NMO velocity that results
in improved reflector continuity and better stratigraphic resolution;
Our technical partnership with ION’s imaging group, a leader in offshore pre-stack depth migration (PSDM) and tomography, gives us access to an incredible suite of imaging technologies, including Kirchhoff, reverse time migration (RTM), and full waveform inversion (FWI). For decades, we have tailored advanced PSDM workflows to serve our clients in every conceivable onshore play – subsalt, thrust belt, carbonate and unconventional. The benefits of our PSDM imaging include:
Corrects for the effects of lateral velocity variations in the geology
that distort the true structural image of the subsurface;
SOFE - Structurally Oriented Frequency Enhancement
We have pioneered a method to recover high- and low- frequency acoustic data. Our SOFE technique uses structure tensors computed on the high signal-to-noise, mid-range frequencies to significantly enhance signal-to-noise of both high- and low-frequencies and improves the resolution of the resulting seismic images and the utility of the acoustic datasets for inversions and attribute extraction. The benefits of SOFE include:
Uncovers masked signal in seismic datasets – does not rely on predictions that
extrapolate beyond the limits of the acoustic signal actually put in the ground;
Delivers broadband, high-resolution interpretable section that ties to well
data without the introduction of unwanted artifacts;
Improves resolution, enabling more accurate mapping of thin beds in stacked
pay reservoirs and the detection of subtle structural features including faults;
Our proprietary technology – WAVO™ – overcomes some of the inherent shortcomings of conventional sample-by-sample AVO analysis. Using a wavelet-based AVO calculation, WAVO improves the accuracy of 2- and 3-term AVO, as well as, azimuthally varying AVO (AVAz). WAVO is less sensitive to NMO stretch and tuning than conventional AVO techniques, improving the ability to identify and evaluate AVO anomalies in challenging environments, such as fractured reservoirs.
We have extensive elastic inversion experience having completed 60+ inversion projects involving over 5,000 square miles of seismic data in North America alone. Using Hampson-Russell’s STRATA software and a proprietary suite of gather conditioning software, we produce high-quality elastic inversion attributes for subsequent reservoir characterization work.
With more than 50 3D-3C projects in almost every geologic environment including carbonates, tight gas, oil sands and shales, we are an industry leader in multicomponent processing experience and technology. As a result of our experience and investment in multicomponent solutions, we have developed an advanced C-wave processing toolkit for the unique shear wave challenges in complex (hard-rock) environments. Our global experience includes:
North America – Fort Worth basin, Appalachian basin, Williston basin, Greater Green River basin
South America – Venezuela, Argentina
Africa & the Middle East – Egypt, Libya, Nigeria, Kuwait
