R&D Consortium on Depth Conversion and Uncertainties

Geovariances R&D consortium - UncerTZ

 

The consortium on Depth Conversion and Uncertainties is a 3-year R&D program starting from Automn 2015 and aiming at developing a new software solution dedicated to depth conversion for the Oil & Gas industry.

 

CONTEXT

Performing depth conversion while assessing related uncertainties is a classical although challenging task in various contexts. Dedicated software and methodologies exist but with various limitations: black box solutions, lack of functionalities, limited models, no uncertainty assessment, etc.

To address the issues that still prevent people from performing efficiently this task, Geovariances is starting a 2-year R&D consortium in partnership with Mines ParisTech focused on the development of a software dedicated to depth conversion for the Oil & Gas industry.

 

CONSORTIUM OBJECTIVES

  • To combine various probabilistic methods relevant for depth converting seismic horizons and quantify related uncertainties.
  • To implement these methods in a new generation software for the Oil & Gas industry. The software will be developed on Geovariances’ new development platform and ultimately available as a standalone product. Direct links with mainstream geomodelers will be provided (including Petrel™ and Earth Modeling™).

 

NEW SOFTWARE BENEFITS AND KEY POINTS

Benefits

  • Global multi-layer conversion approach, which avoids error propagation observed when converting sequentially various horizons from top to bottom;
  • Uncertainty assessment on related GRV/STOOIP volumes.

Some important features

  • Data Quality Control and reconciliation
  • Handling of classical velocity models
  • Spatial characteristics described in a consistent multivariate model
  • Bayesian framework to account for prior knowledge about modeling parameters
  • Base case and uncertainty quantification (e.g. P10-P50-P90 cases)
  • Volumetrics: GRV & STOOIP computations
  • Spill point distribution
  • Sensitivity analysis

Advantages

  • Mines ParisTech and Geovariances combined expertise:
    – Geovariances proven technology (Isatis, Isatoil);
    – Most recent advances supported by the Geostatistics and Geophysics teams of Mines ParisTech
  • Ease-of-use:
    – Modern and user-friendly interface
    – Workflow-oriented approach
    – Efficient embedded visualization facility (2D/3D with slicing capability)
    – Updating procedure
    – Direct link with geomodelers
    – Wide Input / Output data compliance
