Title:
CNT FIBER BASED IMPEDANCE SPECTROSCOPY FOR CHARACTERIZING DOWNHOLE FLUIDS
Document Type and Number:
WIPO Patent Application WO/2013/009501
Kind Code:
A3
Abstract:
The present disclosure relates to an apparatus and method for estimating a parameter of interest of a downhole fluid using a fluid analysis module. The fluid analysis module may include: at least one nano element and a processor configured to estimate an impedance of the at least one nano element. The fluid analysis module may include an AC power supply configured to supply electrical signals at a plurality of frequencies through the at least one nano element. The method may include bringing the downhole fluid into contact with the at least one nano element; supplying electrical signals through the at least one nano element at a plurality of frequencies; generating impedance information for the at least one nano element in response to the electrical signals; and estimating the at least one parameter of interest using the impedance information.
