PetroStrat are now offering Petroleum Systems Analysis (PSA), as part of their world-leading integrated geoscience services. This exciting new capability is delivered by a highly experienced team who joined PetroStrat through the acquisition of CGG-Viridien’s Geology Group (Robertson). They bring decades of petroleum systems modelling knowledge, now fully integrated into our service packages for both traditional energy applications, as well as unconventionals and energy transition sectors.

Petroleum Systems Analysis strengthens PetroStrat's ability to support exploration and development projects by reducing subsurface uncertainty and providing a clearer understanding of hydrocarbon systems.

How Petroleum Systems Analysis (PSA) Can Support Your Subsurface Project

Petroleum systems analysis provides a framework for understanding the origin, migration, and accumulation of hydrocarbons in a basin at different scale (basin to prospect level) helping to guide exploration by reducing risk and supporting efficient subsurface decisions. By integrating PSA workflows with geochemical and geological data, we deliver consistent and calibrated geoscience projects across entire plays, fields, basins.

Example of integrated workflow

Geochemistry

• Petrostrat PSA Geochemistry Examples
• Utilising different geochemical techniques to establish the potential of  several source  rocks  based on rock and fluids data available.

1D Modelling

• Petrostrat PSA 1D Modelling Examples
• Modelling key well and pseudo  locations to obtain the thermal history and rock properties of the AOI.

Maturity Model

• Petrostrat PSA Maturity Modelling Examples
• Thermal Model to generate Source rocks maturity and temperature maps.

Migration Model

• Petrostrat PSA Migration Modelling Example
• Migration Model to predict accumulations and calculate fetch area – charge volumes.

Key capabilities

PetroStrat have delivered PSA projects across a wide range of basins worldwide, covering both conventional and unconventional systems. PetroStrat's approach integrates petroleum systems analysis with geological modelling, ensuring consistency between observations and predictions from basin to prospect scale. By combining PSA workflows with geochemical, geological and reservoir engineering data, the company build robust models that align with field data to support confident decision-making.

Example of PSA services:

• Integrated petroleum systems studies, from basin to prospect scale
• Regional evaluation of Petroleum Systems
• Source rock maturity assessment, organofacies, kinetics modelling,  migration and accumulation of hydrocarbons, oil and gas potential charge access assessment of both, plays and prospects.
• Quantitative prediction of hydrocarbon generation within source kitchens
• Generation and expulsion risk assessment using maturity modelling
• Hydrocarbon phase and column height prediction at basin to prospect scale   
• Prospects charge access and ranking
• Integration of modelling results into overall prospect ranking schemes.
• Quick PSA evaluation of blocks (data packages, licenses round, data rooms)  
• A variety of studies using 1D and/ or 3D approaches, subject to the data available and objectives
• Insights on reservoir quality prediction (Diagenetic processes evolution)
• Suggest analytical geochemical schemes to ground-truth our predictive models.
