This branch of geology studies how rocks deform and what their internal structures reveal about the forces that shaped them. At PetroStrat we use a variety of techniques to better understand the deformational history, including;

• Log & core interpretation and analysis
• Section balancing and restoration
• Structural modelling

Our team help integrate the findings into projects and models to inform decisions about exploration, development, and production. From micro-scale to prospect, basin, and regional / plate level scale and integration into all aspects of exploration geology.

• Integration of data sets from seismic, core, analogues, gravity and magnetic data, to inform a coherent structural model
• Mapping of subsurface structures such as faults, folds, and fractures
• Hydrocarbon trapping and analysis of faulting and fault seal
• Analysis of stress orientations to assess fractures and fluid flow pathways and subsurface geomechanics / well stability assessment
• Fracture identification and analysis in thin section and core – integration with QEMSCAN and AxioScan – borehole acoustic and image logs
• Plate reconstruction and integration of these models into interpretation

Understanding of source rock systems, presence, and maturity is vital to exploration success. Geochemical analyses provide a fundamental dataset for understanding the processes controlling the formation, migration, accumulation and alteration of hydrocarbons.

By providing an overview of these processes, geochemistry is a powerful tool for reducing exploratory risks, improving production strategies and supporting efficient subsurface projects.  By combining geochemical and geological data, we deliver consistent and calibrated geoscience data across individual fields or entire plays.

• Geochemical analysis supports the identification of potential source rocks and active petroleum systems at different scales
• Detailed geochemical inversion of migrated hydrocarbons (seeps and stains) to support the identification of potential source rocks where no other data is available
• Integration of optical, geochemical and geological methods to estimate thermal maturity and reduce uncertainties in thermal models
• Reservoir geochemistry to determine the presence of compartmentalisation, Tar Mats and Gravity segregation (among other processes)
• Establishing oil/gas families and providing source rocks-fluids correlation

PetroStrat provides expert support for identifying and evaluating hydrocarbon plays, prospects and leads across diverse geological settings. Our approach combines geological and geophysical data to deliver clear, evidence-based insights. We map and assess subsurface targets to support confident exploration decisions.
