  • Patent number: 10697888
    Abstract: A system and method are disclosed for configuring an integrated computational element (ICE) to measure a property of a sample of interest. The system includes an illumination source to provide a sample light which is reflected from or transmitted through a sample. A dispersive element disperses the sample light into wavelength portions. An intensity modulation device having an array of electronically controllable modulation elements is disclosed that forms a pattern which modulates the dispersed sample light. Collection optics focuses the modulated sample light on a detector, which generates a signal that correlates to a property of the sample. The electronically controllable modulation elements can be readily altered to conform to a different measurable property of a sample of interest as desired.

  • Publication number: 20200024498
    Abstract: The present disclosure relates to methods and systems for using elastocaloric materials in subterranean formations. A variety of downhole packages, for example, electronic packages and instrumentation packages, are utilized in subterranean formations during hydrocarbon exploration and production operations. Downhole packages are typically designed to operate below a maximum temperature. When a downhole package is placed in the subterranean formation, its temperature may increase as a result of the natural temperature of the subterranean formation in which it is being used. Additionally, many of these downhole packages used downhole generate heat during operation which may raise the temperature of the downhole package. Reaching or exceeding the maximum temperature of a downhole package may result in ineffective operation and/or complete destruction of the downhole package. As a result, the downhole package may need to be frequently replaced.

  • Patent number: 10513922
    Abstract: Methods and systems for monitoring material loss in a downhole environment arising from corrosion and/or erosion include placing a downhole sensor in a borehole. The resistance of the downhole sensor is measured using a four-probe resistance technique in which a power source is provided at two electrodes of the downhole sensor and voltage is measured at two voltage taps. A rise in voltage over time indicates loss of conductive material on the downhole sensor. The conductive material on the downhole sensor may be formed to provide discrete voltage increases for improving reliability of material loss and/or rate of material loss resistance measurements.

  • Patent number: 10502020
    Abstract: Systems and methods for signaling the detection of a fluid change in a wellbore can be used during wellbore operations, such as cementing a casing in the wellbore. The systems and methods involve using burst discs to provide a pressure pulse that can be detected uphole and there by provide a signal related to when a fluid change has reached a predetermined position in the wellbore. The burst discs can be activated to prevent fluid flow in a portion of the wellbore by a sensor that detects a property that is different between two fluids. Once activated, the pressure of the fluid on the burst discs subsequently ruptures the burst disc and creates the pressure pulse.

  • Patent number: 10452065
    Abstract: An autonomous driving vehicle (ADV) is operated using a human-machine interface (HMI). The web server provides the HMI to a computing device in response to an input received from the computing device. An ADV command is entered into the HMI and passed to an interface of the web server. In response to receiving the ADV command, the web server calls a remote procedure call to a proxy server in a backend server for processing by a perception and control module of the ADV. Results of the ADV command are received by the web server interface and stored in results memory with a unique identifier. The web server interface opens a socket that accesses the results memory. In response to a change in the results memory, the socket reads the results memory and provides the ADV command results to the HMI. Multiple HMIs can simultaneously communicate with the web server interface and socket.
