摘要： A wire screen (122) comprises multiple wires (202) running parallel to one another. Each of wires is spaced apart from each adjacent wire at a distance less than a width of an encased microchip. Each of the plurality of wires includes a plurality of straight segments in a plane and bent segments that connect two of the plurality of straight segments. For each of the wires, each bent segments includes a first end, a second end, and a curved portion curved away from the plane. The first end is connected to at least one of the straight segments and separated from the second end a distance greater than the width of the encased microchip. The curved portion includes a diameter greater than the width of the encased microchip.

摘要： A system and method for covering a cellar (49) at a wellhead to prevent and control fluids and gasses from the cellar (49). The covering includes a mat (50) that circumscribes a wellhead tubular that projects upward from the cellar (49). A split seam (80) in the mat (50) extends radially from the opening to the mat (50) outer periphery which allows the mat (50) to be placed around the wellhead tubular. A fastener joins the ends of the mat (50) that meet at the split seam. The mat (50) includes a collar (82), which mounts to the mat (50) along the opening and extends axially away from an upper surface of the mat (50). The collar (82) is secured to the wellhead tubular with a strap. Two discharge lines project through the mat (50) into the cellar (49), one for pumping into the cellar (49), and one for withdrawing fluid that has collected in the cellar (49).
