Empirical correlation for porosity deduction from X-ray computed tomography (CT)
For obtaining reservoir petrophysical properties, for example porosity, non-destructive methods such as X-ray computed tomography, CT, seems to be precise and accurate. Porosity is deducted from the CT image with a single scan via different techniques, such as pore space detection by image segmentation techniques then correlation with porosity. More than one hundred samples with carbonate li...
متن کاملDissolution-Driven Permeability Reduction of a Fractured Carbonate Caprock.
Geochemical reactions may alter the permeability of leakage pathways in caprocks, which serve a critical role in confining CO2 in geologic carbon sequestration. A caprock specimen from a carbonate formation in the Michigan sedimentary Basin was fractured and studied in a high-pressure core flow experiment. Inflowing brine was saturated with CO2 at 40°C and 10 MPa, resulting in an initial pH of ...
متن کاملμCT on narrowly fractured natural rock samples from a hydrocarbon reservoir
Micro-Computed Tomography (μCT) is used for imaging narrowly fractured natural rocks from the subsurface of the Vienna Basin, Austria. The dolomites from the Hauptdolomit Formation represent a successfully producing reservoir for hydrocarbons (mainly gas). However, the heterogeneity of the rocks and their fracture networks make conventional predictions on economically viable exploration of the ...
متن کاملNoble Gas Release and Flow Through a Granite and Basalt
An experimental system we developed combines triaxial rock deformation and mass spectrometry to measure noble gas flow before, during, and after rock fracture. Gas flow through a granite and basalt in its unfractured condition allows estimation of “native” permeability. Geogenic noble gas is released during triaxial deformation (real time) and is related to volume strain and acoustic emissions....
متن کاملResearch on Stress Sensitivity of Fractured Carbonate Reservoirs Based on CT Technology
Fracture aperture change under stress has long been considered as one of primary causes of stress sensitivity of fractured gas reservoirs. However, little is known about the evolution of the morphology of fracture apertures on flow property in loading and unloading cycles. This paper reports a stress sensitivity experiment on carbonate core plugs in which Computed Tomography (CT) technology is ...
