  • Publication number: 20240151111
    Abstract: Systems and methods are provided to facilitate connection of multiple stage completions. A first completion stage is deployed at a wellbore location. Subsequently, the next completion stage is moved downhole into engagement with the first completion stage. The completion stages each have communication lines that are coupled together downhole via a wetmate connection. Systems and methods for determining an orientation of the communication lines relative to the wellbore are also provided.

  • Publication number: 20240139191
    Abstract: Disclosed are compounds and compositions that bind to the La-related protein 1 (LARP1). LARP1 has roles as both a repressor of translation and stabilizer of mRNA transcripts, and therefore functions as a molecular switch in cancer biology. LARP1 also upregulates the proliferation of RNA viruses. Accordingly, the compounds and compositions disclosed herein that bind to LARP1 may be used for treating or preventing cancer or viral infections in a subject.

  • Publication number: 20240076942
    Abstract: Systems and methods for monitoring and control in downhole well applications are provided. The system and methodology may be combined with a variety of completions or other types of well equipment deployed downhole to enable both electrical and fiber optic communication with downhole components. For example, the system enables both electrical and fiber optic communication for operating and monitoring of downhole completion systems or other systems.

  • Patent number: 11922515
    Abstract: Platform-agnostic digital assistant methods and apparatuses are provided. The apparatuses and methods include a processor configured by a memory to receive user data from a storage containing informational contents. The processor is configured to establish a communication channel with an entity and utilize the communication channel to receive first information related to a user. The processor is configured to extract at least one user datum from the first information and modify the informational contents of the storage based on at least one of the user datum and the first information. The processor is further configured to initiate an action related to the user based on at least one of the first information, the user datum, and the informational contents.

  • Patent number: 11753908
    Abstract: A screen assembly. The screen assembly may include an inner tubular, a filter screen, a shunt tube, and a perforated shroud. The inner tubular may be configured to flow a formation fluid produced at a first production zone of a formation having multiple production zones that is downhole of the screen assembly. The filter screen may be disposed radially outward from the inner tubular and configured to filter a formation fluid produced at a second production zone that is proximate the screen assembly prior to the formation fluid entering an annulus between the filter screen and the inner tubular. The shunt tube may be disposed radially outward from the filter screen to flow a fluid to a location within the borehole that is downhole of the screen assembly. The perforated shroud may be perforated shroud disposed radially outward from the shunt tube.

  • Patent number: 8503036
    Abstract: A system and method of reducing noise in output image data is provided. Grayscale image data having a plurality of pixels is received and processed. During processing, pixels which may produce noise are identified, and a mask associated with the image data is generated. The mask provides information related to the pixels, such as opaque and transparent regions for overlaying the pixels. The image data and the mask are compressed and stored. The mask assists in preventing the identified pixels from being visible when the image data is output, thereby reducing the noise in the image.

  • Patent number: 8041143
    Abstract: One embodiment is a method for suppressing background inaccuracies in binary to grayscale image conversion. A binary image is converted to a grayscale image using a neighbor map. An image enhancement function is applied to the grayscale image to suppress background inaccuracies in the grayscale image. Another embodiment is method for converting a binary pixel of a binary image to a grayscale pixel of a grayscale image and suppressing noise in the grayscale image using selective filtering of the binary image. Another embodiment is a method for converting a binary image to a first grayscale image and suppressing noise in the first grayscale image to produce a noise suppressed grayscale image using selective filtering of the first grayscale image.

  • Patent number: 8023150
    Abstract: A method and system reconstructs a contone image from a binary image by first tagging pixels to identify one of a multiplicity of image content types. The tag information and the pattern of bits surrounding the pixel to be converted to a contone value are used to reconstruct a contone image from a binary image. The pattern of bits in the neighborhood is used to generate a unique identifier. The unique identifier is used as the address for a lookup table with the contone value to be used wherein each lookup table corresponds to an image context type.

  • Patent number: 7991235
    Abstract: A light compression method that error diffuses image data provided with luminance and chrominance channels. During error diffusion, a higher number of bits are allocated to the luminance channel. A decompression method for the image data based on sigma filtering is also provided. By manipulating the bits in the luminance and chrominance color spaces, the image output quality may be increased in reconstructed images.
