Abstract: A fluid-sampling system that includes a downhole tool string with a fluid-sampling tool coupled thereto, and a fluid sampling probe coupled to the tool via a probe extension arm, the fluid sampling probe having an oval pad that contacts a borehole wall, one or more fluid inlets which receive a formation fluid, and a plurality of screens between the borehole wall and the one or more fluid inlets which filter the formation fluid. The fluid-sampling system further including one or more offset arms coupled to the tool which contact the borehole wall.

Abstract: A sand control screen (40) includes a perforated base pipe (42) and a filter layer (50) that has micro-perforations (52) therein. The filter layer (50) is attached to the base pipe (42) along the entire length of the filter layer (50). Channels (46) are formed between the base pipe (42) and the filter layer (50) to allow fluid to flow therebetween. The sand control screen (40) is formed by micro-perforating a length of material, such as sheet metal, to form the filter layer (50), creating channels (46) that will allow fluids to flow between the base pipe (42) and filter layer (50), wrapping the filter layer (50) around the base pipe (42), attaching the filter layer (50) to the base pipe (42) along the length of the filter layer (50) and creating a seam between the two edges of the filter layer (50).
