The tests were performed at net confining stress and at ambient conditions to evaluate if large differences were observed in results. Gravimetric measurements were simultaneously obtained to ensure data quality. Two different available imaging...

We also studied the spatial and temporal resolution of the inter-well analyte distributions...

... Abstract Identifying key geological features (e.g. karsts, faults, fractures) are extremely important for well planning and mitigating drilling hazards. To identify and characterize these features, a high-resolution diffraction study was conducted in a pilot area which successfully detected...

... textures using the stereomicroscope. This helped in selecting representative cuttings for the main identified textures. These cuttings were CT imaged at a resolution ranging from 40 to 4 microns/voxel resolution in order to confirm their rock textures and sedimentary structures for better characterization...

While we were able to highlight the caveats of upscaling on complex chemical floods we continue to investigate and design a solution that would encompass combination of chemicals (surfactant, alkaline and polymer) as well as handle of concentration/salinity changes. resolution...

... ). As a result, the simulation technique has the advantage of being highly computationally efficient, enabling the modeling of capillary and buoyancy driven quasi-static flows in very high-resolution geological models (10-100s of million gridblocks) within minutes to a few hours. IP models fluid flow in a porous...
