KINGDOM Colored Inversion

Create Acoustic Impedance Attributes Using Log Data

Most interpreters prefer to use seismic inversion as the primary data type for seismic interpretation as it represents a simplified signal compared to the normal seismic response. The inverted data represents true geological layering rather than the wavelet response at an interface.

KINGDOM Colored Inversion is a tool that enables interpreters to quickly generate a relative acoustic impedance data type from the reflection seismic data for the purpose of more accurate, more confident seismic interpretation.

Colored Inversion is a proven technique that is fast and easy to apply to seismic data, yet it produces results that match more sophisticated and compute intensive techniques such as sparse spike inversion. KINGDOM Colored Inversion matches the well character within the seismic bandwidth and automatically performs phase correction, thereby minimizing the risk of interpreting incorrect or unwanted seismic events and improving the speed and accuracy of the interpretation. This increase in interpretation efficiency easily offsets the time spent creating the inversion data.

Benefits

  • Cost effective way of increasing interpretation productivity and accuracy
  • Fast and robust method of generating a seismic inversion data type ideally suited for use by all interpreters
  • Matches seismic data to well log data to produce cleaner data with less noise and less signal instability
  • Simple for the interpreter to set up and use
  • Ideal 'quick look' inversion tool for use prior to more detailed inversion studies

Features

  • Supports single and multi-well analysis
  • Automatic seismic to well phase correction
  • Sonic log to time-depth curve and check shot calibration module
  • Fully integrated with KINGDOM
  • Highly customizable, user friendly interface
  • Simple data requirements:
    • One or more wells with a sonic or velocity log
    • A time-depth or check shot curve for the well or a depth formation top and corresponding time grid
    • A seismic reflection data type
    • Ideally the well will have also have density log, but this can be automatically derived from the sonic log using Gardner's equation in the software
