摘要： 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.

摘要： A subterranean formation can be monitored using motion data. For example, a series of time-lapsed images of a well site can be received by a processing device. Motion data can be extracted from the series of time-lapsed images. The motion data can correspond to a difference between images in the series of time-lapsed images. Changes to a surface of the well site can be determined based on the motion data. Features of a subterranean formation of the well site can be determined based on the changes to the surface.

摘要： A sensor is calibrated to determine a first offset parameter. The sensor has a boundary condition that affects the first offset parameter. A first viscosity of a first fluid is calculated using a calculated parameter adjusted by the first offset parameter. The calculated parameter is calculated from an output of the sensor being applied to the first fluid. An operational decision is made based on the calculated first viscosity.

摘要： Downhole fluid sensing device is disclosed for determining heat capacity of a formation fluid produced by a sampled subterranean well, the sensor package having an annulus shaped, elongate body defining a cylindrical fluid sampling space, the sensor package and the sampling space having a common longitudinal center axis. The elongate sensor package body has a fluid entrance port that provides well fluid ingress into the fluid sampling space and a fluid exit port that provides well fluid egress out of the fluid sampling space. A heat source is coupled to the elongate sensor package body and located along a portion of the fluid path, and the heat source inputs heat into sampled well fluid. Finally, temperature sensing devices (located between the fluid entrance port and fluid exit port measure heat conducted to the sampled well fluid, wherein each of the temperature sensing devices is radially spaced from the heat source.

摘要： An optical cable can include one or more graphenic elements disposed about one or more optically transmissive fibers. A graphenic element can be a coating of graphene or amorphous graphite, a ribbon of graphene or amorphous graphite, or fibers of graphene or amorphous graphite. The graphenic element provides a path for electrical conduction while the optically transmissive fiber provides a path for optical transmission. An optical cable as disclosed herein can include a plurality of electrical and optical paths with a much smaller diameter and weight than traditional cables.

摘要： 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.

摘要： 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.
