Geovariances launches R&D consortium for depth conversion software

Geovariances has announced its consortium on Depth Conversion and Uncertainties, a two-year R&D programme starting from spring 2015 and aiming at developing a new software solution dedicated to depth conversion for the oil and gas industry.


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 two-year R&D consortium in partnership with Mines ParisTech focused on the development of a software dedicated to depth conversion for the oil and 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 and 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


  • 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.

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


Mines ParisTech and Geovariances combined expertise:

  1. Geovariances proven technology (Isatis, Isatoil);
  2. Most recent advances supported by the Geostatistics and Geophysics teams of Mines ParisTech


  • 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
