Zusammenfassung: | A tubular body for a wellbore. The tubular body comprises an elongated pipe body having a box end and a pin end, defining a wall. The tubular body includes a filter screen. The filter screen is disposed around an outer diameter of the wall along at least a portion of the elongated body. The filter screen defines a cylindrical body having slots there along. A plurality of compressible particles are held within the filter screen. Each of the compressible particles is fabricated to collapse in response to fluid pressure communicated through the slots. A method of mitigating pressure within a trapped annulus is also provided herein. The method includes the use of at least one of the tubular bodies along a casing string. |
