In addition to deriving the porosity, the T 2 distributions (related to pore size distributions) can unlock a whole new suite of parameters which can be derived from cuttings including the relative size of the pores and the bound vs...

... gradient equipped 12 MHz NMR spectrometer. The experimental technique begins with carrying out as-received NMR scans on shale core plug samples to measure the amount of water and oil in the samples. Micro-CT scans are used to identify and reject plug samples that have micro-cracks. These samples...

... scan voxel. For upscaling purposes, we established a quadratic correlation between the grey values in a CT scan and the porosities measured on core plugs. This correlation allowed us to generate a synthetic porosity log of millimeter resolution. After that, the length scale was increased by moving...

... analysis study has established the feasibility of permeability predictions from dielectric core plug measurements using an empirical model based on phase shift and amplitude dispersion in the kHz range (Norbisrath et al., 2017, 2018). The technique has now been adapted to dielectric wireline logs using...

... from a comparative study among three commercial core laboratories on core saturation measurement techniques made on samples from the BPS. One part of the study was to confirm that core plugs from the Middle Bakken/Three Forks section of the BPS cleaned using the Dean-Stark core-cleaning protocols...

... dielectric log. Laboratory dielectric measurement on core plugs extracted from subsurface formations provides a way to address these issues and improve the interpretation of the well logs (Josh et al., 2009; Seleznev et al., 2016). Here, we present experimental methods to determine matrix permittivity from...

Once core plugs are cleaned and dried, regaining the clay fabric with restored state techniques is most often not achieved and causes overestimation of both porosity...
