  • Patent number: 9504946
    Abstract: A method and apparatus are provided for separating droplets of finely aerosolized elemental mercury from a fluid stream in which the droplets are dispersed, particularly a gaseous stream. In the method, a precious metal wire capillary surface or precious metal-coated wire capillary surface is contacted with the gaseous stream, causing the aerosolized droplets to deposit on the capillary surface and by capillary action to coalesce with other of such droplets. The surface is oriented to allow the mercury to flow by gravitational forces and capillary action to the lowermost portions of the surface, where it accumulates and can be collected. Metallic capillary surfaces comprised of finely braided strands of silver, gold, palladium, platinum, or rhodium wire, or wire coated with one or more of these metals, are particularly preferred.

  • Patent number: 9434026
    Abstract: A filtering assembly is laid flat on an outer shroud. An inner drainage layer is set over the filtering assembly while laid flat such that the inner drainage layer overlaps the filtering assembly. The inner drainage layer is sealed and secured to the outer shroud by diffusion bonding or welding while overlaying the filtering assembly. With the filtering assembly held firm between the inner drainage layer and the outer shroud a spiral winding procedure is commenced to roll the flat assembly into a cylindrical shape. The edges are sealed by welding or diffusion bonding. The spiral winding and seam closure can be done on a perforated base pipe or the base pipe can be inserted into the finished assembly at a later time and secured. Alternatively the filtering assembly and outer shroud, with or without the drainage layer can be wound over a perforated base pipe or a complete screen assembly.

  • Publication number: 20150144330
    Abstract: A method is for use with subterranean formations, such as oil and/or gas reservoirs. In some examples (e.g., production examples), the method improves the production from that formation. Some of the examples of the method describe selecting both an exertive force (e.g., a pressure) to apply at a wellbore, but together with a drawdown pressure at the wellbore to modify operations (e.g., improve production) at that subterranean formation. The selection of one or both of the exertive force and drawdown pressure may be based on the downhole environment at that wellbore, which can include the porosity and/or permeability of a near-wellbore formation radially surrounding a wellbore. The exertive force and drawdown pressure may be specifically selected to modify the porosity and/or permeability of the near-wellbore formation.

    Abstract: A wellbore assembly comprises a tubular member adapted to be connected to other tubular members, the tubular member having a side wall defining a hollow interior and an array of openings therethrough to permit material into the interior. A screening element extends about the tubular member over the array of openings to control the material that reaches the array of openings. A stress relieving arrangement associated with the screening element permits relative movement between the screening element and the tubular member to absorb stress build-up within the screening element whether due to mechanical or temperature induced forces that would tend to distortion the screening elements. In a preferred arrangement, the wellbore assembly serves to maintain solids control in production wells while accommodating stresses and strains that occur within the tubular members in those wells.

    Abstract: Thermally crosslinked polysulfone may be made from linear polysulfone, such as polyethersulfone, in powder form blended with a powdered inorganic peroxide such as magnesium peroxide or another oxygen source, to form a mixture followed by compression inside a mold. The mixture is cured at a an elevated temperature, for instance above 325° C., for an effective period of time to form a dense object. The object is then boiled in water, optionally under pressure, to remove the salt to give a structure that is open and porous which may be used as a filtration device on a downhole tool for hydrocarbon recovery. If a powdered salt is not used, a thermally crosslinked, solid, void-free polysulfone is made which may be strong and rigid at ambient, surface temperatures, but is an elastomer at elevated downhole temperatures, and is thus suitable for use as a packer or an O-ring.

  • Publication number: 20090308596
    Abstract: Non conductive supports flank the mounting location of ribs for a wire wrap screen so as to limit penetration into the wire being fed over the ribs and resistance welded notwithstanding variations of applied force from the weld roller. Optionally the wire can be pre-rolled to approximately its end diameter in the finished screen ahead of the time it contacts a rib so as to minimize bending the wire over the rib which thins the wire. The supports are preferably ceramic and provide equal penetration of the rib into the wrap wire despite variations in loading by the weld roller.

  • Publication number: 20080289815
    Abstract: A screen assembly that is used with a well includes a base pipe, a screen and ribs. The base pipe has a non-perforated section and has a longitudinal axis. The screen at least partially circumscribes the non-perforated section of the base pipe, and the ribs extend longitudinally in an annular space between the screen and the non-perforated section. A flexible member (e.g., a wire) is wrapped around the ribs. Various other mechanisms may be used instead of the ribs and flexible member in the annular space. In this regard, such annular standoffs such as a corrugated material, a member that has longitudinal channels, and a member formed from a first set of wires that is interwoven with a second set of wires may be used. Alternatively, longitudinal channels may be formed in the outer surface of the base pipe.
