Basin & Petroleum Systems Analysis

BPSM utilises key aspects of geological, geophysical and geochemical interpretation into a unified, integrated subsurface model. Depending aims/objectives and data availability a bespoke workflow will be proposed

Coupled thermal-burial histories are fundamental to BPSM, integrating tectonic, sedimentological and fluid properties, calibrated to temperature, pressure and palaeothermometric (e.g., vitrinite reflectance) data

Quantifying the magnitude and timing of source maturity, and predicted hydrocarbon volumes and phase

Provides critical understanding to source rock maturity, reservoir quality & seal effectiveness

Modelling of reservoir charge volumes/phase/timing, migration and alteration processes 

Discrete scenarios (e.g., migration) or Monte Carlo Simulations (e.g., expulsion volumes in fetch area, PVT prediction of reservoir fluids)

Source potential is a function of many factors, including (but not limited to) organic content, kerogen type, maturity, expulsion efficiency & thickness, all of which vary temporally and spatially. When properly integrated with calibrated basin models, the petroleum generation/expulsion volumes and phase can be predicted

Integrating source maturity through time, migration routes (e.g., fault seal), reservoir properties, PVT conditions and alteration processes (e.g., biodegradation) allows an estimation of prospect volumes and phase in both deterministic scenarios and stochastic uncertainty analysis. If in a mature basin, calibration to neighbouring discoveries is critical

IGI's workflow always includes risk & uncertainty analysis with distributed ranges of input parameters (e.g., TOC, geothermal gradients), dynamically showing which elements are most sensitive to predicted charge volumes and phase

Coupled thermal-burial histories are fundamental to BPSM, integrating tectonic, sedimentological and fluid properties, calibrated to temperature, pressure and palaeothermometric (e.g., vitrinite reflectance) data

For most projects, even building a grid-based 3-D model is a relatively efficient process, providing impactful and powerful results in what is usually a fraction of the time taken for seismic and geological interpretations

Project deliverables include key outputs (e.g., digital maps for GIS/Petrel). Modelling files are also included to be updated as and when new data become available
