Reservoir Condition Pore-scale Imaging of Multiple Fluid Phases Using X-ray Microtomography
X-ray microtomography was used to image, at a resolution of 6.6 µm, the pore-scale arrangement of residual carbon dioxide ganglia in the pore-space of a carbonate rock at pressures and temperatures representative of typical formations used for CO2 storage. Chemical equilibrium between the CO2, brine and rock phases was maintained using a high pressure high temperature reactor, replicating condi...
متن کاملPore-scale contact angle measurements at reservoir conditions using X-ray microtomography
Contact angle is a principal control of the flow of multiple fluid phases through porous media; however its measurement on other than flat surfaces remains a challenge. A new method is presented for the measurement of the contact angle between immiscible fluids at the pore scale at reservoir conditions (10 MPa and 50 C) inside a quarry limestone through the use of X-ray microtomography. It is a...
متن کاملX-ray microtomography application in pore space reservoir rock.
Characterization of porosity in carbonate rocks is important in the oil and gas industry since a major hydrocarbons field is formed by this lithology and they have a complex media porous. In this context, this research presents a study of the pore space in limestones rocks by x-ray microtomography. Total porosity, type of porosity and pore size distribution were evaluated from 3D high resolutio...
متن کاملThe Imaging of Dynamic Multiphase Fluid Flow Using Synchrotron-Based X-ray Microtomography at Reservoir Conditions
Fast synchrotron-basedX-raymicrotomographywas used to image the injection of super-critical CO2 under subsurface conditions into a brine-saturated carbonate sample at the pore-scale with a voxel size of 3.64μm and a temporal resolution of 45s. Capillary pressure wasmeasured from the images by finding the curvature of terminal menisci of both connected and disconnected CO2 clusters. We provide a...
متن کاملMicrotomography and Pore-Scale Modeling of Two-Phase Fluid Distribution
Synchrotron-based X-ray microtomography (micro CT) at the Advanced Light Source (ALS) line 8.3.2 at the Lawrence Berkeley National Laboratory produces threedimensional micron-scale-resolution digital images of the pore space of the reservoir rock along with the spacial distribution of the fluids. Pore-scale visualization of carbon dioxide flooding experiments performed at a reservoir pressure d...
