Abstract: An apparatus includes a body. The body includes first and second clamping mechanisms that are configured to grip a tubular member of a beam pump unit at first and second axially-offset locations along the tubular member, respectively. The body also includes a base positioned at least partially between the first and second clamping mechanisms. The apparatus also includes a strain gauge coupled to the base and configured to measure a strain on the tubular member as the tubular member moves. The apparatus also includes a gyroscope configured to measure an orientation, an angular velocity, or both of the beam pump unit as the beam pump unit operates. The apparatus also includes an accelerometer configured to measure an acceleration of the beam pump unit as the beam pump unit operates.

Abstract: A method for detecting operational issues in a beam pump unit includes receiving sensor data representing a position of and a load on the beam pump unit, using a sensor coupled to the beam pump unit, generating a surface dynacard based on the sensor data, predicting a source of inefficiency in the beam pump unit based at least in part on the surface dynacard using a machine learning algorithm, and identifying one or more corrective actions to take to address the source of inefficiency.

Abstract: An apparatus for measuring strain in a polished rod of a beam pump unit includes a body having an upper wide section, a lower wide section, and a narrow section having a reduced width in comparison to each of the upper and lower wide sections. A bore is formed in the narrow section. The apparatus also includes at least two connectors configured to connect the body to the rod. The bore is positioned between the two connectors in a direction that is parallel to an axis of the rod. The apparatus further includes a strain gauge positioned in the bore, so as to measure strain in the rod between the two points of connection.

Abstract: A method includes receiving acoustic signals from one or more acoustic sensors that are coupled to a beam pump unit. The method also includes identifying a frequency of the beam pump unit in the acoustic signals. The method also includes detecting an outlier in the acoustic signals based at least partially upon the identified frequency. The outlier represents an operational issue with the beam pump unit.

Abstract: The invention relates in particular to a detector for two-dimensional analysis of a flux of photons or neutral particles. The detector comprises a solid plane converter (5) constituted by a two-dimensional matrix of cells (such as 9c), an array of charge-multiplying wires (6) using stimulated ionization of a gas, and a cathode grid (7). The cells both convert the photons or neutral particles and collect the charge, and the ionization is preferably stimulated until self-regulating streams of electrons appear (streamer mode).The invention has application to imaging devices.

Abstract: The invention relates to a neutral particle detector for providing one-dimensional analysis of a flux (14) of neutral particles which reach it in a sheet. The detector comprises a solid plane converter (17) disposed at a grazing incidence, a grid of charge amplifying wires (18) making use of stimulated ionization of a gas, and charge collecting tracks (19). The tracks are disposed in the immediate proximity of the converter and are subjected to the same electrical potential as the converter. The invention is applicable to imaging.

Abstract: The present invention relates to a method and apparatus for measuring subsidence by evaluating the distance between radioactive markers which have previously been implanted in the formation traversed by a borehole. The apparatus comprises an elongate body containing at least two nuclear detection assemblies which are spaced apart along the longitudinal axis of the body. Each detection assembly inludes at least one position sensitive detector for detecting position along the longitudinal axis of the body. Measurements are performed while the apparatus is held stationary opposite the markers.
