Abstract: A system for monitoring a composition includes: an electromagnetic source that emits a beam; one or more evanescent field sensing element inside a tubular structure, arranged in series along a flow direction of the composition, and configured to be in direct contact with the composition; a waveguide that directs at least a portion of the beam to the evanescent field sensing element as an incident beam; and a detector configured to obtain a spectral distribution of the fingerprint beam. The evanescent field sensing element provides partial or total internal reflection of the incident beam at an interface between the evanescent field sensing element and the composition, and the incident beam interacts with the composition to form a fingerprint beam.

Abstract: An untethered apparatus for measuring properties along a subterranean well includes a housing, and one or more sensors configured to measure data along the subterranean well. The data includes one or more physical, chemical, geological or structural properties in the subterranean well. The untethered apparatus further includes a processor configured to control the one or more sensors measuring the data and to store the measured data, and a transmitter configured to transmit the measured data to a receiver arranged external to the subterranean well. Further, the untethered apparatus includes a controller configured to control the buoyancy or the drag of the untethered apparatus to control a position of the untethered apparatus in the subterranean well. The processor includes instructions defining measurement parameters for the one or more sensors of the untethered apparatus within the subterranean well.

Abstract: A pressure cell system includes a pressure cell configured to house a sample within inner walls of the pressure cell. An injection system is configured to inject an injectable medium into the pressure cell in a gap between the sample and the inner walls. A heating element is configured to provide heat to the injectable medium in the pressure cell. A pressure gauge is configured to measure pressure inside the pressure cell. A temperature gauge is configured to measure temperature in the pressure cell. A top is configured to provide a pressure resistant lid on the pressure cell. A coaxial resonator system is configured to capture microwave measurements of the sample at different temperatures and pressures after the sample is placed inside of the pressure cell, a top of the pressure cell is closed, and after the injectable medium is injected into the pressure cell in the gap.

Abstract: A computer-implemented system includes a downhole tool in a bottom hole assembly attached to a drill string, configured to perform gas measurements during drilling operations. The downhole tool includes a housing to house the downhole tool; sensors positioned along external walls of the housing and including coaxial resonators; electrical circuitry located inside the downhole tool and configured to enable communication by, and operation of, the downhole tool; at least one processor configured to convert scattering parameter 11 signals received from sensors to permittivity values and determine signatures from permittivity values. A memory stores data collected by sensors. A sensor system monitors changes from a baseline signal of drill mud produced during the drilling operations, the changes based at least in part on signatures determined from permittivity values. The downhole tool provides communications to surface systems when a gas kick event is detected by the downhole tool.

Abstract: A pressure cell system includes a pressure cell configured to house a sample within inner walls of the pressure cell. An injectable medium is injected by an injection system of the pressure cell system into the pressure cell in a gap between the sample and the inner walls. The injectable medium in the pressure cell is heated by a heating element of the pressure cell system. A pressure inside the pressure cell is measured by a pressure gauge of the pressure cell system. A temperature in the pressure cell is measured by a temperature gauge of the pressure cell system. Microwave permittivity measurements of the sample are captured by a coaxial resonator system of the pressure cell system. The microwave permittivity measurements of the sample are captured at different combinations of temperatures and pressures. The microwave permittivity measurements include measurements of permittivity of gas under pressure at plural frequencies.
