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.

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 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

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.

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:

1. Geovariances proven technology (Isatis, Isatoil);
2. 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
