Calculate High-Resolution 3D Seismic Attributes

Geoscientists have found that seismic attributes are a valuable addition to seismic amplitude data in structural and stratigraphic interpretation, particularly in highlighting subtle geological features, such as faults, fractures, channels, and karst features. Many seismic attributes provide a more "geological-looking" data volume than seismic amplitude data, speeding understanding of the geological setting of plays, and also enhancing presentations.

LMKR Volume Attributes for 3D seismic allows calculation of curvature and geometric attributes such as semblance and Event Similarity Prediction (ESP), based on spectral decomposition of the seismic amplitude data. It also supports calculation of time-based attributes based on time windows, instantaneous attributes based on Hilbert-transformed traces, and expression-based attributes calculated from mathematical combinations and operations on other attribute volumes. The spectral decomposition algorithm that is embedded is patented, and allows higher resolution decomposition than conventional approaches.

LMKR Volume Attributes reads and writes both SEG-Y and GeoGraphix 3dx data volumes, allowing easy integration with LMKR GeoGraphix applications as well as standalone use.


Flexibility

Expression-based mathematical combinations of attributes allow interpreters to generate custom attributes to enable the best use of attribute analysis for a given geological play.

Accuracy

The LMKR patented spectral decomposition technique gives better resolution than conventional methods - a factor which is critically important in today's unconventional plays.

Integration

LMKR GeoGraphix 3dx and 3dh seismic formats are supported, for rapid "what if" testing and visualization of attributes in the area of interest. Volume Attributes also supports SEG-Y input and output for data transfer to other applications.

Ease of use

Modern tab-based user interface and interactive menus with tool-tips guide even novice attribute users through their workflows.
