Using attributes is fundamental to seismic interpretation. The Paradise Attribute Generator places best-in-class post-stack seismic attribute calculations in the hands of seismic interpreters and specialists alike using easy-to-follow ThoughtFlows™ and geoscience-focused visualization capabilities. The Paradise attribute library includes a comprehensive list of Instantaneous attributes as well as commercial algorithms and workflows developed by the Attribute Assisted Seismic Processing and Interpretation (AASPI) group at the University of Oklahoma, led by Dr. Kurt Marfurt.
Families of Attributes
- Spectral Decomposition
Seismic attributes differ in their relative contribution to information (energy) in a given volume. In Paradise, Principal Component Analysis (PCA) is used to identify those attributes that are the most prominent and quantify their relative contribution to a volume. Using an Eigen spectrum chart, the relative contribution is presented both graphically and numerically, taking the guesswork out of selecting the right attributes seismic interpretation.
Multi-Attribute Classification uses the Self-Organizing Map (SOM) unsupervised machine learning process to improve the seismic interpretation of stratigraphic facies and their distributions. Applied at single sample scale in Paradise, this technique has demonstrated the ability to resolve thin beds that are below classic seismic tuning thickness. The SOM methodology has also proven to define potential fluid effects on seismic data given the appropriate seismic attributes. When used with the unique interactive 2D Colormap in Paradise, the distribution of one or more neural classes can be calibrated with geology. The Machine Learning Geobody application uses the results from Multi-Attribute Classification and the deep learning tools in Paradise to detect geobodies and calculate volumetrics.

Interactive 2D Colormap
Paradise is the only software product in the industry with a 2D Colormap representing neuron classifications of attributes. The 2D Colormap is used with the Paradise Universal Viewer to select and isolate specific neurons that have classified multiple seismic attributes from the SOM process. The 2D Colormap enables the seismic interpretation of neuron-identified geologic features and their geometries while providing the relative contribution of each seismic attribute per neuron.
The blending of attributes in an RGB display can dramatically enhance the visibility of geologic features within the seismic data. The Color Blending application is a 3D visualization tool that co-renders three separate attribute volumes (e.g., three spectral decomposition volumes) into a single volume for enhanced seismic interpretation. When applied to seismic data, Color Blending or co-rendering can highlight geologic and geophysical features, thereby improving interpretability..
Machine learning geobodies are isolated at the bin level, enabling volumetric estimates of hydrocarbons
Machine Learning Geobodies
Generating geobodies from machine learning is unique to the Paradise AI workbench. Machine Learning Geobodies quantify the volume of seismic interpretation features, including hydrocarbon pore volume. The value of the tool is obtaining estimated volumetrics early in the seismic interpretation workflow. Geobodies are defined from one or more neurons from either a Multi-Attribute or Seismic Facies classification. The output is a three-dimensional visualization of geological features and potential reservoirs. Once generated, industry-standard volumetric calculations are applied to geobodies to estimate in-place and recoverable hydrocarbons where reservoir data is available. Using Paradise to identify geobodies empowers interpreters to:
- Investigate geobodies at the sample level of each neuron
- Capture details on areas of interest, including volumetrics and statistics
- Edit selected geobodies by filling in areas or pruning extraneous samples
- Export specific geobodies to an interpretation system for further analysis
Deep Learning (DL) Fault Detection
Built on CNN technology, the Deep Learning (DL) Fault Detection application is equipped with general pre-trained deep learning engines (models), enabling their application to a wide range of seismic data without the need for user-provided fault examples for training. Using Graphics Processing Unit (GPU) technology, the tool dramatically reduces the time to identify faults in a volume, accelerating the seismic interpretation workflow. Seismic interpreters use the Fault Detection application to compare aggressive and conservative results quickly, providing more time to focus on refining the results.

Note the greatly improved fault continuity, resolution, and reduced noise from the CNN-based fault detection method.
Deep Learning (DL) Seismic Facies Classification
The new DL Seismic Facies classification tool enables the identification of structural and stratigraphic facies patterns based on supervised, deep learning (CNN) technology. Seismic facies and other patterns present in seismic data, such as potential Direct Hydrocarbon Indicators, multiples, etc., can be identified in a seismic volume through training of the engine (model) on the desired facies. The 3D extent of these features can provide significant and valuable insights into the seismic interpretation process.
Well Log Visualization
Paradise® brings seismic data to borehole and lithofacies resoltuion in feet/meters. Use the new Well Log Visualization capability in version 3.4 to compare machine learning classification results and other seismic attributes to traditional well logs. View well logs, formation tops, and extracted log curves together within a cross-section to corroborate machine learning to ground truth.
The interpreter can customize the Well Log View, by adding tracks and changing the properties of all data within them. This feature is a powerful tool in the process of correlating machine learning results to the reservoir properties determined by conventional well logs.
GPU Computing (GPU)
Many of the more computationally intensive processes in Paradise use GPU computing to accelerate seismic interpretation. The new deep learning processes that use convolutional neural network (CNN) technology, and many of the seismic attributes, are examples where GPU computing is applied to deliver performance. And more attributes in the rich Paradise library are being migrated from multi-threaded CPU to GPU processing.

The Paradise – Petrel* Connector allows seismic interpreters to import and export data to and from Paradise seamlessly and quickly, increasing the efficiency of seismic interpretation using machine learning.
The Petrel Connector to Paradise is installed on the same machine with Petrel and appears as an icon on the Petrel ribbon. Simply open the Paradise Connector, select the data to be moved to Paradise, drag and drop the data items onto the Petrel Connector dialog, and select Export. Import from Paradise to Petrel is equally straightforward. Multiple items can be exported at once by selecting the folder to export, such as all wells. The products of machine learning and deep learning in Paradise, such as Deep Learning Seismic Facies, Faults, and Multi-Attribute Classification volumes can be imported easily into Petrel for further analysis.

Paradise Scripting Language
The Paradise Scripting Language (PSL) is a powerful procedural and interpreted language for geophysical signal and neural network analysis. The language includes over 600 geoscience-specific commands for analyzing geoscience data. PSL is designed for geoscientists and researchers to develop new geophysical data procedures. Unlike Python or other programming tools, many geoscience constructs are pre-built and readily available in PSL, saving time while providing a rich toolset for analysis and investigations.
The Paradise Script Processor (PSP) is a software application for optimized multi-thread vectorized performance. PSP modes include interactive operations, numerical batch processing, and multi-batch parallel processing. Included with PSL is the Paradise Script Editor (PSE) to write and run scripts interactively.
Below is a list of the minimum technical hardware and software requirements for running a single instance of the Paradise client and server on a dedicated workstation.
Windows 10 Pro
MS SQL Server 2012
8+ processing cores

File storage capacity depends on several different variables: See note below*
10Gb ethernet connection for networked data storage or USB 3.0 connection for external storage devices
*File Storage capacity is dependent on the size of the surveys and attributes volumes, plus interpretation files, e.g., faults, horizons, wells, etc. Local storage (on the server running Paradise) is encouraged for evaluation purposes; however, if a centralized network storage facility is to be used for project files, a 10 Gb LAN connection is recommended between the target server and project file storage facility.
