Abstract: A wellbore screen for screening particulates in wellbore fluid comprising: a base pipe having an inner bore; and a screen section disposed in a section of the base pipe, the screen section comprising (i) an outer jacket having an inner facing surface and apertures extending through the outer jacket, (ii) an inner wall having an outer surface, an inner surface and a port extending through the inner wall from the inner surface to the outer surface, (iii) an annulus formed between the inner facing surface of the outer jacket and the outer surface of the inner wall, (iv) a filter medium for the apertures of the outer jacket; and (v) a filter disc disposed in the port of the inner wall, wherein wellbore fluid flows from outside the base pipe into the inner bore through the apertures, the filter medium, the annulus, and the filter disc.

Abstract: There is provided a wellbore screen having a base pipe and a strip of filter medium wrapped around the base pipe. The strip of filter medium includes one or more layers of woven steel mesh of various weave patterns, fibers sizes, and/or thread tensions. During the construction of the screen, the strip is wrapped around the base pipe under high tension. The strip has two lengthwise edges that may overlap to form a bonded interface.

Abstract: A wellbore tubular including: an inner tubular wall; an opening through the inner tubular wall; an outer tubular wall positioned about the inner tubular, the outer tubular wall including an opening therethrough; a chamber between the inner tubular wall and the outer tubular wall; and a chemical treatment material in the chamber and positioned between the opening of the inner tubular wall and the opening of the outer tubular wall. The wellbore tubular may be used in downhole fluid treatment process.

Abstract: A wellbore screen includes a base pipe including a wall, an inner bore surface and an outer surface, an opening formed through the base pipe wall and a filter cartridge mounted in the opening. In one aspect, the wellbore screen includes an impermeable layer relative to the opening and the impermeable layer may be selected to be substantially impermeable when in a closed position in the opening to passage of fluids through the opening and, the impermeable layer is at least one of (i) selectively openable to permit fluid flow through the opening and (ii) selectively closeable when triggered to close the opening. In another aspect, the opening may include a tapering diameter from one end to the other and the filter cartridge may include an outer diameter formed to reversibly and substantially correspondingly taper relative to the opening to permit a taper lock fit in the opening.
