Integrate QSI Workflows Early in the G&G Cycle to Reduce Uncertainty

The integration of early quantitative seismic interpretation (QSI) into the seismic interpretation process is one of the most effective methods for reducing uncertainty in the long term. Adding QSI to daily interpretation work can help companies thrive, even in today’s economy. Paradigm® Quantitative Seismic Interpretation modules are directly integrated into the interpretation platform.  They benefit from a high-definition viewer, and direct access to data stored in Paradigm Epos® -based data repositories.

Prestack and poststack integration in a single 3D canvas for interactive Quantitative Seismic Interpretation
 
Paradigm QSI quantifies the relevant parameters of the subsurface for each rock unit within the geometrical interpretation framework.  Our technology provides answers to questions about rock type, lithology, reservoir properties, fluid fill, elastic properties, and geomechanical properties, and help you better evaluate your probability of drilling success. The workflow traditionally begins with prestack migrated data organized in offset/angle gathers or angle stack volumes.  The user reviews and conditions the data in 2D for more detailed work, or 3D Canvas for more integrated interpretation.  Both windows provide attractive functionalities for this, including a comprehensive set of dedicated algorithms for pre-conditioning the data and an interactive framework for visualizing and running the process.
 

Flexible QSI Packaging

Paradigm QSI solution packages have been configured specifically for different data characterization goals.  For the interpreter, the QSI-RFP (Rock and Fluid Properties) package is aimed at providing deeper insight into the subsurface, for enhanced understanding of the impact of lithology and fluid on seismic data.  For those who wish to go beyond interpretation, a QSI-RFP for Reservoir Geophysics package enables users to dig deeper into their data using techniques such as elastic inversion and automatic residual moveout analysis and correction. 

Major features of the QSI-RFP packages include:

  • Multi-disciplinary crossplot
  • AVO analysis
  • Colored Inversion - a tool to generate impedances simply while interpreting.  Fast and accurate, fully integrated into Paradigm SeisEarth®.
  • A comprehensive and interactive Synthetic Utility for calibrating single or multiple wells in both time and depth.
  • Fluid substitution to consider “what if” scenarios and accurately analyze the effects of fluid on seismic data.
  • A wedge modeling tool, to analyze the effect of bed thickness on seismic amplitude

Additional features in the QSI-RFP for Reservoir Geophysics package:

  • Velocity analysis with Paradigm FastVel®
  • Machine learning to correlate logs and seismic data
  • Simultaneous inversions using prestack data (full collection of gathers)
For specialists who need to characterize unconventional and other fractured reservoirs, Paradigm offers the QSI-AzFP (Azimuthal Analysis of Fracture Properties) package. QSI-AzFP is a comprehensive system for performing azimuthal analysis of Fracture Properties, providing accurate information about the orientation, intensity and density of fracture/tectonic-stress systems.

Major features in QSI-AzFP include:

  • Azimuthal-dependent residual moveout analysis (FastVel/VVAZ) and amplitude variation (AVAZ) analysis for automated extraction of azimuthally dependent attributes
  • Support for both full-azimuth OVT (sectored) and EarthStudy 360® gathers for analysis and display
  • Customizable vector map displays
  • Includes FastVel and full-azimuth AVA analysis, and gather conditioning
The optimal use of EarthStudy 360 results is key in many assets, and is the only way to maximize ROI on extensive data acquisitions. However, much data is still processed by sectoring data. Paradigm 15 provides tools to work on both sectored and non-sectored AVAZ data.
