摘要： A technique facilitates nonintrusive monitoring of a fluid constituent within an overall fluid flow. The system and methodology may be used downhole to monitor, e.g., the volume fraction of water in produced well fluid. The system comprises a sensor system combined with a component, e.g. a well component, having a flow passage for receiving a fluid flow. At least a portion of the fluid flow moves through the sensor system which may comprise a main electrode, a guard electrode, and an insulator to isolate the main electrode and the guard electrode. The main electrode and the guard electrode are oriented circumferentially around the fluid flow to obtain capacitance data on the fluid flowing through the sensor system. The capacitance data may be processed to determine the fraction of a specific constituent within the fluid flow, e.g. to determine the volume fraction of water in a well fluid flow.

摘要： Techniques involve determining the conductivity profile of a formation from a well between a surface location and a borehole location. The method involves placing a first sensor at the surface location, a second sensor located at the borehole location, obtaining a first signal by detecting Schumann resonances from the electric field occurring at the first location, obtaining a second signal by detecting Schumann resonances from the electric field occurring at the second location with the second sensor; and combining the first and the second signal to determine the conductivity profile of the formation between the first location and the second location.

摘要： A technique facilitates evaluation of a fluid flowing through a tubing and includes at least one sensor deployed along an interior of the tubing. Each sensor comprises a plurality of electrodes and insulation material disposed between the electrodes to isolate the electrodes from each other and to facilitate resistivity measurements. The plurality of electrodes comprises electrodes for emitting an electric current and for monitoring voltage so as to enable resistivity measurements with respect to fluid flowing through the tubing. The resistivity measurements may be used to determine a constituent fraction, e.g. a water fraction, of the fluid flowing through the tubing.
