New features and new capabilities have been added to Imager 5.3 improving its usability and data handling capabilities
User Interface and Data Control
• Significant performance improvements have been made to this version of Imager. Improvements have been made both to the importers and in the main code operation. Very large data files can be loaded and analyzed while maintaining good operating performance
• The user interface of the tables, panel view, and stereographic views has been improved so that they are dynamically linked. Selecting features in the tables, panel view or stereographic view will highlight that feature in the other views and depth center the feature in the image and in the measurement table.
• All plots now consistently updated when measurement table values change.
New Functionality
• Importing Previously Analyzed Fractures: Fracture true dip and true dip direction measurements and associated classification made using another image interpretation package can be imported using a fixed ASCII, 4-column text format.
• Fracture Classification Enhancements: A color classification has been implemented to the Fracture Classification Dialog to let the user specify and assign a different color to the fracture instead of the system default color.
• Custom Fracture Classification: A new user interface has been implemented to let users load their own fracture classification definitions as separate text files into Imager 5.3.
• New Data Import Capabilities: The following table provides a list of the acoustic, electrical and optical data compatible with Imager5.3. Imager 5.3 has been enhanced so that it can import virtually any new type of image data. The import functions allow users to import data from any of the following generic data structures:
o 4 pad tool (i.e., FMS, OBMI/Dual OBMI)
o 6 pad tool (i.e., EMI/XRMI, Star)
o 8 pad tool (i.e., FMI)
o 2D array (i.e., processed 2D array from the EMI, Star, etc.; 2D acoustic data or any 2D array)
o Interpolated buttons (sparsely sampled LWD data – RAB, etc.)
