Quantifying CO2 transport and average effective reaction rates in the subsurface is essential to assess the risks associated with underground carbon capture and storage. We use X-ray microtomography to investigate dynamic pore structure evolution in situ at temperatures and pressures representative of underground reservoirs and aquifers. A 4 mm diameter Ketton carbonate core is injected with CO...

The map of permeability distribution in the reservoirs is considered one most essential steps geologic model building due to its governing fluid flow through reservoir which makes it influential parameter on history matching than other parameters. For that, petrophysical properties that are tuned during matching. Unfortunately, prediction relationship between static petrophysics (porosity) and ...

The flowing material balance (FMB) method is widely used to evaluate geological reserves because it does not require shut-in wells and uses daily production data. original FMB based on a homogeneous medium model, but the reservoir often heterogeneous. In this study, equations are derived for radial composite reservoirs naturally fractured reservoirs, effect of parameters estimation analyzed. st...

Abstract Seismic characterisation of deep carbonate reservoirs is considerable interest for reservoir distribution prediction, quality evaluation and structure delineation. However, it challenging to use the traditional methodology predict a deep-buried because highly nonlinear mapping relationship between heterogeneous features seismic responses. We propose machine-learning-based method (rando...
