During drilling operations, encountering highly pressurized brine zones or low-pressure zones can alter the amount of brine in an oil-based mud, also known as oil-brine-ratio (OBR). Thus, monitoring the OBR is an important measurement to determine an

The complex permittivity at microwave frequencies of benzene, toluene, ethylbenzene, o-xylene, m-xylene, and p-xylene was measured at 25 °C. Given the extremely low conductivity of these solvents, ...

The ultimate goal of our work is to develop an electromagnetic multi-frequency integrated system to enable real-time and in-situ characterization during high power electromagnetic (HPEM) operations, e.g. logging while lasing (LWL) or logging while mi

Microwave measurements of slabbed, whole core surfaces from calcite-rich shales are correlated to mineralogy quantified from elemental maps measured using micro X-ray Fluorescence (µXRF) across those same surfaces. The nondestructive microwave measu

[EN] Permittivity is a useful tool to characterize the composition and quality of many geomaterials. In general, the non-resonant permittivity measurement methods exhibit a higher degree of uncertainty than their resonant counterparts. In resonant me

During well-logging operations, the depth of a logging tool is usually obtained by measuring the length of the wireline cable that suspends the tool in the well. In some cases, a secondary depth reference is obtained with a casing collar locator (CCL

This paper investigates numerically the feasibility of using quarter wavelength coaxial resonators for permittivity measurements of pressurized gases, as found in the subsurface. The non-short-circuited end of the resonator is facing the inside of a

Complex permittivity measurements were conducted for four crude oils and a gas condensate at temperatures ranging from 25 °C to 125 °C. The measurements were conducted using a liquid test fixture and results are reported for frequencies between 50
