Multi-frequency dielectric scanning logging is an advanced method that plays a critical role
in evaluating unconventional oil and gas reserves and residual oil distribution. This method …

Hydrocarbon saturation is an important petrophysical parameter in reservoir evaluation and
reserve calculation. Dielectric dispersion logs have been widely used to estimate the …

Measurements of complex resistivity spectra (CRS) are performed on core plugs from a wide
variety of carbonates in a log sweep from 0.1 to 100,000 Hz inside a pressurized chamber at …

Electromagnetic (EM) formation evaluation currently relies on low-frequency resistivity and
high-frequency dielectric measurements that are typically not interpreted jointly. In …

Petrophysical models are used to estimate formation water saturation and salinity from
dielectric dispersion data. These models are sensitive to other attributes of the formation …

Variable depositional cycles and severe diagenesis are among the main contributing factors
to the complex pore networks encountered in formations, such as carbonates. This …

Abstract The Bakken Petroleum System (BPS) is composed of both conventional and
unconventional units exhibiting significant variations in lithology, rock texture, clay content …

Determining hydrocarbon content from conventional resistivity measurements in freshwater
shaly sands formations is challenging because the resistivity depends on the clay …

In this work, we establish an effective medium model to describe the low-frequency complex
dielectric (conductivity) dispersion of dilute clay suspensions. We use previously obtained …

Dimensional analysis was performed to understand the physics of ionic dispersion in
reservoir rocks and to identify the factors influencing the cation exchange capacity (CEC) of …
