    Abstract: A frequency sensor comprises a surface functionalized with a reactant sensitive to an analyte and a vibration detector coupled to the functional surface to detect a frequency of a fluid having the analyte and located on the functional surface during vibration thereof. The frequency sensor comprises a measurement circuitry coupled to the vibration detector to determine a frequency shift over time of the detected frequency, wherein the frequency shift corresponds to the presence of the analyte which has reacted with the reactant.

    Abstract: Methods for determining a density of a fluid are provided. The method can include passing the fluid through a conduit, measuring a vibration of the conduit by distributed acoustic sensing via a fiber optic cable coupled to the conduit, and generating a vibrational signal indicative of the measured vibration. At least a portion of the vibration of the conduit can be produced by the fluid passing therethrough. The method can also include measuring a temperature of the conduit and generating a temperature signal indicative of the temperature. The method can further include calculating the density of the fluid passing through the conduit by using the vibrational signal and the temperature signal.

    Abstract: A fluid is received into a sample tube. A processor causes an energy to be applied to the sample tube to induce vibration in the sample tube at a resonant frequency of the sample tube containing the fluid. The processor stops the supply of energy to the sample tube. The processor monitors an amplitude of the vibration of the sample tube as the amplitude of the vibrations diminish over a period of time. The processor uses the monitored amplitude to calculate an RF of the sample tube containing the fluid. The processor uses the calculated RF to calculate the viscosity of the fluid.

    Abstract: An apparatus includes a helical flow tube in a formation testing tool. A current injector injects an electromagnetic current into the flow tube. A receiver coil is positioned to produce a receiver coil signal in response to the electromagnetic current. A processor is coupled to the receiver coil to calculate a conductivity of a fluid flowing through the flow tube based on the receiver coil signal.

    Abstract: Technologies for providing optical analysis systems using an integrated computational element with laterally-distributed spectral filters are described. A measurement tool contains an optical element including a substrate and a plurality of spectral filters supported by the substrate and arranged at different lateral positions with respect to a path of light to be received from a sample during operation of the measurement tool. Each spectral filter is formed to transmit or reflect a different subset of wavelengths in a wavelength range. Additionally, each spectral filter has a respective area exposed to the light from the sample, such that the respective areas are related to a property of the sample. The wavelength range can include wavelengths in a range from about 0.2 μm to about 25 μm. Additionally, the sample can include wellbore fluids and the property of the sample is a property of the well-bore fluids.
