Integrating Geology and Petrophysics into Numerical Models – A Step Towards the Digitalization of Rocks

Monsees, A. C.; Busch, B.; Subhedar, A.; Nestler, B.; Hilgers, C.

Abstract (englisch):
Detailed petrographic analyses as well as petrophysical measurements are well established standard methods used for reservoir characterization by the E&P industry. Advances in computational power over the last decade combined with the ongoing challenge of digitalization present new opportunities regarding fluid flow through porous siliciclastic sandstones. Based on a case study from a northern German Rotliegend gas reservoir (depth >5000 m), we introduce a workflow that calibrates numerical flow simulations with geologic lab data. X-ray micro computed tomography (μCT) images of samples representing the reservoir heterogeneity were used to reconstruct the 3D geometry of the studied sandstones. The digitized rock was integrated with mineralogical data relevant for reservoir quality like mineral content (Morad et al. 2000, Taylor et al. 2010) and clay coating coverages (Ajdukiewicz et al. 2010, Busch et al. 2017). Petrophysical measurements of porosity (He pycnometry) and permeabilities were conducted and integrated. Permeability was measured under constant (1.2 MPa) and elevated confining pressures (2-50 MPa), as well as at room temperature and elevated temperatures (140° C).
