... of the proppant pack is determined by loading the proppant at a 2-pound mass per square foot basis. The conductivity of the proppant pack is then measured as a function of closure stress applied. Each closure stress exerted on the proppant pack is to be maintained for 50 hours. This final measurement...

... Abstract In this work, the dispersion coefficient of solvent in heavy oil/bitumen is innovatively determined by employing an inverse approach to accurately reproduce the measured temperature, pressure, and production profiles in a heated vapour extraction (H-VAPEX) process, thereby...

... are properly accounted, and the resultant pressure and thermal profiles calculated for a flow period of 30 days. Assuming the capacity to fully cap the well (complete shut-in), two shut-in pressure and thermal profiles are subsequently determined by using the flowing condition as a precursor. A Hot Shut...

... Abstract We present two methods to measure contact angles inside porous media using high-resolution images. The direct determination of contact angle at the three-phase contact line is often ambiguous due to uncertainties with image segmentation. Instead, we propose two alternative approaches...

... conditions. The obtained data were processed by compositional simulation to determine the diffusion coefficients. The diffusion coefficients measured for methane + hexadecane and methane + decane are in agreement with the existing literature data. For methane + live oil systems, however, the diffusion...

... Abstract Rock mechanics triaxial tests and well logs are the main source for determination of mechanical properties of reservoir. These methods obtain values for mechanical properties corresponding to parts of the formation close to the well area. The experimental approach is much more limited...
