Permeability Upscaling for Carbonates from the Pore-Scale Using Multi-Scale Xray-CT Images

bility due to large permeability contrasts. The most accurate upscaling technique is employing Darcy’s law. A key part of the study is the establishment of porosity transforms between highresolution and low-resolution images to arrive at a calibrated porosity map to constraint permeability estimates for the whole core.

Techniques for Extracting Reliable Density and Porosity Data From Cuttings

Reservoir samples are essential for proper formation characterization. The use of drilling cuttings has been proposed as an alternative to coring. Despite some loss, contamination, and depth uncertainty (typically within 10 ft), cuttings show strong potential to represent all the formations encountered during the drilling of a well. This paper discusses the capabilities of various laboratory instruments to extract reliable density and porosity data from cuttings.
