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.
- 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.
- 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:
- Geovariances proven technology (Isatis, Isatoil);
- 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
