PetroMod: Managing Uncertainties

PetroMod software manages uncertainties using advanced statistical PetroRisk software and through calibration—simplified calibration with actual or hypothetical wells in the entire PetroMod suite through PetroMod 1D, or using the crustal heat flow processor in conjunction with the PetroMod heat flow calibration tool to generate accurate boundary conditions for optimal simulations.

Managing uncertainties with PetroMod PetroRisk software

PetroRisk software operates as a controlling framework on all PetroMod packages, assessing uncertainties and following the entire migration path to calculate probability estimates for accumulations. You can define uncertainties in the input data and both quantify and statistically evaluate their effects on the simulation outcome. Exploration risking is performed within the framework of a fully integrated dynamic geologic model. Results are displayed in 1D, 2D, and 3D viewers, with additional overlays for specified output parameters. Probability estimates and statistical information for potential hydrocarbon accumulations can also be selected and displayed. PetroRisk software allows users to define well data for calibration, run inversion (MCMC), evaluate results, and shift desired parameters on the master model to achieve their targets.

Managing uncertainties through calibration

The PetroMod 1D tool provides access to all modeling features, including statistics. Single point data can be constructed from scratch, imported from the Well Editor, or extracted directly from PetroMod 2D and 3D models. Calibration data from wells can be used to generate heat flow trends and lithology parameters, which can be used directly by the 2D and 3D simulators.

The Heat Flow Calibration Tool quickly calibrates 3D models to the temperature and vitrinite reflectance measurements provided from project wells. All maps are calibrated at once; results are written in heat flow maps that are imported into the 3D model in all 3D PetroMod packages. The fully integrated Crustal Heat Flow preprocessing tool calculates the heat flow history of 2D and 3D PetroMod models. This tool takes subsidence, timing, and crustal parameters as input to generate accurate stretching factors and higher-quality paleo heat flow maps, reducing uncertainty for faster map generation.
