  • Publication number: 20230145343
    Abstract: A method for supplying, via an electrical interface, an output electrical power to an electrical load that is downhole in a borehole formed in a subsurface formation, includes generating mechanical energy from a flow of a fluid being delivered into the borehole; converting the mechanical energy into an input electrical power; storing the input electrical power into a primary capacitor, wherein the input electrical power has a variance that is greater than a variance threshold. The method includes performing the following operations while continuing to generate the mechanical energy generated from the flow of the fluid, in response to determining that at least one load criteria is satisfied, discharging the input electrical power from the primary capacitor to the electrical load to power a downhole operation by the electrical load.

  • Patent number: 10781689
    Abstract: A tool including a probe deployable within a wellbore and an optical analysis device coupled to the probe is provided. The optical analysis device includes a two-dimensional (2D) waveguide layer to transmit and to disperse an electromagnetic radiation according to wavelength and including detector elements disposed along an edge, each detector element providing a signal associated with a pre-determined wavelength portion of the electromagnetic radiation. The optical analysis device also includes a substrate layer electrically coupled to receive the signal from each of the detector elements and form a spectrum of the electromagnetic radiation with the processor. A method for using the tool in a wellbore application, a pipeline application, or a reservoir storage application is also provided.

  • Patent number: 10533938
    Abstract: Conventional optical analysis tools containing an integrated computational element may have an operational profile that is too large for convenient use within confined locales. Optical analysis tools having a miniaturized operational profile can comprise: an electromagnetic radiation source that provides electromagnetic radiation to an optical train; and an optical computing device positioned within the optical train. The optical computing device comprises a planar array detector having at least two optical detection regions. At least one of the at least two optical detection regions has an integrated computational element disposed thereon. The planar array detector and the integrated computational element are in a fixed configuration with respect to one another.
