Imperial College Consortium on Pore - Scale Modelling Second Progress Report
We describe the early stages of a poreto coreto reservoir-scale investigation of wettability variation and its impact on flow during oil recovery. We use a threedimensional pore-scale network representation of a Berea sandstone to predict relative permeability and capillary pressure hysteresis. We successfully match experimental data for the water-wet case, and then focus upon the effect of var...
متن کاملImperial College Consortium on Pore - Scale Modelling Yearly progress and final report January 3 rd 2011
Displacement experiments using the porous plate method were conducted on water-wet sandstones to measure the capillary trapping of oil by waterflooding as a function of its saturation after primary drainage. Three sandstone samples ranging in porosity from 12.2% to 22.1% were considered. Experiments on two samples were conducted at an elevated temperature and back-pressure of 343K and 9MPa resp...
متن کاملFinger Thickening during Extra-Heavy Oil Waterflooding: Simulation and Interpretation Using Pore-Scale Modelling
Although thermal methods have been popular and successfully applied in heavy oil recovery, they are often found to be uneconomic or impractical. Therefore, alternative production protocols are being actively pursued and interesting options include water injection and polymer flooding. Indeed, such techniques have been successfully tested in recent laboratory investigations, where X-ray scans pe...
متن کاملDiffusion Pore Imaging
Nuclear magnetic resonance (NMR) diffusion measurements are widely used to derive parameters indirectly related to the microstructure of biological tissues and porous media. However, a direct imaging of cell or pore shapes and sizes would be of high interest. For a long time, determining pore shapes by NMR diffusion acquisitions seemed impossible, because the necessary phase information could n...
متن کاملComputational Permeability Determination from Pore-Scale Imaging: Sample Size, Mesh and Method Sensitivities
In this work, a complete work flow from pore-scale imaging to absolute permeability determination is described and discussed. Two specific points are tackled, concerning (1) the mesh refinement for a fixed image resolution and (2) the impact of the determination method used. A key point for this kind of approach is to work on enough large samples to check the representativity of the obtained ev...
