    摘要： A downhole system includes a tubular having a plurality of spaced apertures radially extending through a wall of the tubular. A section of the tubular blocking radial fluid flow through the wall between an interior and exterior of the tubular. The section arranged from a first end to a second end of the tubular. A plurality of filter pucks respectively inserted into at least some of the plurality of apertures. The filter pucks each including a body configured for insertion in one of the apertures and a filtering element within each body; and, at least one control or monitoring line arranged on the section. Further is a method of controlling sand in a downhole system.

    摘要： An embodiment provides a device that includes a shape memory member having a sealed outer surface and a permeable inner mass and a selected fluid placed and sealed within the inner mass at a first temperature. The selected fluid is released from the inner mass when the shape memory member is heated to a second temperature.

    摘要： A tubular centralizer is secured to the tubular for run in. The profile for run in is small so that damage to the centralizer is minimized during run in. When the string is in position the centralizer is actuated to change shape or volume to engage the surrounding borehole to centralize the tubular for subsequent operations such as cementing or in the case of screens for gravel packing. The centralizer can be a shape memory material that is initially compressed at above its transition temperature to hold the smaller shape. At the desired location after run in it is brought above the transition temperature and changes back to the original shape or volume to centralize the tubular string. The structure can be spaced ring segments or a cohesive ring structure with an undulating profile or radiating blades to create flow spaces in the annulus where it is deployed for flow of a sealing material or gravel, for example.
