Improve structural and stratigraphic interpretation of the reservoir by extracting key information from seismic data.
Seismic attributes decompose or isolate information contained in seismic data into specific components or attributes. The information captured depends on the nature of the attribute.
Seismic Attribute Benefits
- Multi-attribute volume visualization in SeisEarth facilitates attribute correlations
- Calculate one or more attributes in parallel
- Attribute previews with an on-the-fly calculation option for immediate attribute analysis in the interpretation platform
- Attributes can be computed either by CPU or GPU
- Automatic time-depth conversion embedded in attribute interface
- Integration with crossplot tool
- Versatile and powerful user-defined attribute calculator for infinite customized attribute options
Seismic Attribute Features
Emerson E&P offers a comprehensive suite of seismic attributes that includes:
- Complex and Standard Attributes: over twenty attributes calculated from the Hilbert’s and Fourier transform that capture unique information about the seismic wavelet that can be associated with structural or stratigraphic features.
- Structural attributes: dip, azimuth, continuity and Lightscape™. These attributes capture structural information by measuring different geometric components of the lateral relationships of seismic data.
- Curvature attributes: includes a selection of 11 attributes that are often used to detect folds, faults and fractures that are highlighted by measuring different properties of the rate of change of dip and azimuth along a seismic reflection or horizon.
- Coherence Cube: Patented, industry-leading technology derived by Eigen and Semblance processing used to extract structural and stratigraphic features from seismic data volumes.
- Spectral Decomposition: highlights geologic characteristics that respond differently to different frequency ranges of the seismic signal. Ideal for analyzing channels, thin beds, and other subsurface features.
- Automatic Fault Extraction (AFE): Automated workflow for extraction of faults from discontinuity attributes.
- Dip Steered Enhancement: attribute that removes noise and enhances the continuity of the seismic data by applying a smoothing filter along the dip of the seismic reflections.
- Principal Component Analysis: mathematical transformation that can be used to extract key information from multiple volumes so the interpreter can reduce data dimensionality without sacrificing information, the analysis also gives insights about how attributes related to each other and identification of which attributes provide unique information.
- User Defined Attribute or seismic calculator: accessible from the user interface or from the command line (batch) allows interpreters to create their own customized attributes that can be defined using mathematical and function operations between volumes and maps.
- Trace Processing: allows interpreters to perform poststack processing operations on seismic volumes by defining a sequence of steps that include as options: filters, scaling, phase rotation, despiking, spectral balance, Automatic Gain Control, bulk shift and the full suite of complex trace attributes
- Interval Attributes: Computation of maps of multiple seismic attributes extracted over a vertical interval.
- Seismic attribute analysis in SKUA-GOCAD™ modeling suite.
