For identifying storage sites and characterisation of the storage complex: our geoscientists create 2D and 3D maps of the subsurface, showing the geometry, potential leakage pathways and properties of potential storage reservoirs and cap rock layers.

The petrophysical services of PanTerra are fully integrated with the core analysis results and the geology results. The petrophysical analysis of PanTerra will deliver porosity-permeability relations calibrated with core measurements – including uncertainty analysis.

The calculations of the storage volumes, include core analysis work and small-scale geology work on thin sections to assess the remaining pore space after depletion, for depleted gas fields, or for aquifers. Moreover, it also includes the geomechanical analysis on the existing pore space. PanTerra’s reservoir geology capabilities include SEM, XRD and petrographic analyses, that provide detailed geological information on the composition of the caprock and the pore volumes and possible CO2 reactivity on the storage reservoir. Based on the above input data calibrated models are then obtained for reactive core flow modelling.

Following a full integration of sedimentological, structural, petrographic and reservoir quality data, interpretation of the reservoir architecture can be undertaken. Including analysis of core data, calibrated against wireline logs, well test/production data (eg. MDT/PLT) and SCAL data. In addition, the interpretation and analysis of the caprock, aquifers and overburden will lead to a static model with properties populated.
