Abstract: Methods and systems of electromagnetic sensing in a wellbore are presented in this disclosure for monitoring annulus fluids and water floods. An array of transmitters and one or more receivers are located along a casing in the wellbore. A transmitter in the array and one of the receivers can be mounted on a same collar on the casing forming a transmitter-receiver pair. The receiver can receive a signal originating from the transmitter and at least one other signal originating from at least one other transmitter in the array, wherein the signal is indicative of a fluid in the wellbore in a vicinity of the transmitter-receiver pair and the at least one other signal is indicative of another fluid in a formation around the wellbore. The receiver can further communicate, via a waveguide, the signal and the at least one other signal to a processor for signal interpretation.

Abstract: Provided are turbidometers and fluorometers having a unique form-factor to accommodate a number of optical components in a confined geometry. This provides the ability to compensate for change in light intensity from an optical source even in a closed-loop manner. The ability to package reference and signal detectors, along with a relatively large diameter LED light source in a confined geometry is particularly suited for applications requiring small-diameter sensors, such as multi-parameter sonde devices having a total diameter that is in the sub-two inch range.

Abstract: A fluid monitoring assembly includes a conduit having a wall defining a lumen for carrying fluid. A sensor mount is integrally formed with the wall of the conduit and extends generally transverse with respect to a longitudinal axis of the conduit, the sensor mount including an aperture defining an inner surface extending to the lumen. The assembly includes a sensor configured to be removably secured within the sensor mount, the sensor having an elongate body terminating at one end thereof in a sensing portion, the elongate body having a male projection on a portion thereof and configured to rest within the inner surface of the sensor mount. The assembly further includes a housing having first and second portions connected to one another, the housing defining an interior portion configured to encapsulate the conduit, at least a portion of the elongate body of the sensor, and the sensor mount.

Abstract: A multi-directional water sensor comprises a housing having multiple conductive pads on the outer surface of the housing at locations spaced around the periphery of the housing, an electrical power source coupled to the conductive pads, and multiple electrical conductors located inside the housing and connecting multiple pairs of the contacts so that electrical current can flow between different pairs of the contacts when they are connected by water. The housing may have a generally rectangular shape, with the contacts located at the corners of the housing. The multiple electrical conductors are connected to an alarm that is energized when electrical current flows between any pair of the contacts.

Abstract: A device, apparatus and method for trapping metal ions and detecting metal ion contamination in a solution provide a semiconductor device formed on a semiconductor substrate and including an N-well formed over a P-type substrate and at least a contact portion of the N-well in electrical contact with the solution. When the semiconductor device is optically illuminated, a P/N junction is formed as a result of photovoltaic phenomena. Metal ions from the solution migrate to the contact area due to the voltage created at the P/N junction. The semiconductor device includes a conductive structure with conductive features separated by a gap and therefore in an initially electrically open state. When the ions migrate to the contact area, they precipitate, at least partially bridging the gap and creating conductance through the conductive structure. The conductance may be measured to determine the amount of metal ion contamination.
