... dielectric data are measured on clean outcrop core samples of both carbonate and sandstone. The data are analyzed by using the traditional dielectric interpretation models assuming that m equals to n i.e., considering matrix and hydrocarbon as one phase and water as the second phase, the MN approach...

... Coring is the only acquisition technique used to directly measure the fluid saturations inside the reservoir by extracting and measuring the fluids contents in core samples. Fluid saturations obtained using other surveillance techniques, such as well logs or tracers, are indirectly inferred based...

..., it has been shown that a significant portion of this void filled porosity is occupied by formation water at reservoir conditions. The discussion below will show several experiments validating this idea including: comparisons between preserved and non-preserved core samples, re-testing old core to measure...

... on these challenging wells. The improvements include: - 1.5-in. diameter core samples, on a 35,000-psi tool - New high-powered coring tools with significantly more power for cutting Lower Tertiary well cemented rock (Wilcox, etc.) - Higher torque and horsepower at the bit - High-powered surface systems and high...

... significant challenges originating from uncertainties in the acquired data, assumptions used to interpret these data and more broadly, due to increased relative uncertainty associated with tight, low-porosity formations. For example, the crushing of the core samples, which is required for efficient fluid...

... on core samples from different rock types, covering a range of wettability and water saturation levels. These measurements are inputs to the non-linear models, which are simultaneously solved to estimate wettability and water saturation for each core sample. We verify the reliability of wettability...

..., unsteady-state methods often fail to address viscous and capillary effects which are commonly present in low-porosity and low-permeability core samples. The objectives of this paper are (a) to compare unsteady-state and steady-state methods (stationary liquid) using two desaturation techniques, porous...

.... The outputs of this workflow include water saturation and wettability. To experimentally verify the reliability of the introduced workflow, we chemically alter the wettability of core samples to be water-wet, mixed-wet, or oil-wet. We confirm and quantify the wettability level in each core sample using...
