  • Publication number: 20200132872
    Abstract: Seismic image processing including filtering a three-dimensional (3D) seismic image for random noise attenuation via multiple processors. The filtering includes receiving a 3D image cube of seismic image data, decomposing the 3D image cube into 3D sub-cubes for parallel computation on the multiple processors, designing and applying a two-dimensional (2D) adaptive filter for image points on 2D image slices of the 3D sub-cubes via the multiple processors to give filtered 3D sub-cubes, and summing the filtered 3D sub-cubes to give a filtered 3D image cube.

  • Patent number: 8962096
    Abstract: A method for coating a substrate includes impacting a substrate with a plurality of particles such that the particles adhere to the substrate, bonding the particles to the substrate to form an overlayer, and crosslinking the particles in the overlayer to coat the substrate with a crosslinked polymer coating. The particles comprise a polyphenyl polymer. An article includes a substrate and a crosslinked polymer coating bonded to the substrate. The crosslinked polymer coating is a product of crosslinking polyphenylene sulfide, polyphenylsulfone, self-reinforced polyphenylene, or a combination thereof on a surface of the substrate.

  • Patent number: 8939222
    Abstract: A downhole element to isolate or complete a wellbore includes a shape memory material including polyphenylene sulfide. The polyphenylene sulfide is the cure product of being cured at a temperature of about 200° C. to about 400° C., for a total time of less than or equal to 200 hours. The shape memory material is thermally activated between an actuated and unactuated shape, and the polyphenylene sulfide in the shape memory material is a closed cell foam, open cell foam, or solid.

  • Patent number: 8876944
    Abstract: A system for separating fluids of a fluid mixture including a filter element operatively arranged for enabling a first component of a fluid mixture to flow therethrough while impeding flow of at least one other fluid component of the fluid mixture. An additive is configured to improve a first affinity of the filter element for the first component relative to a second affinity of the filter element for the at least one other fluid component of the fluid mixture. A method of separating fluids is also included.
