    摘要: A swelling packer is covered with a material that is preferably in a tubular form and slipped over the swelling element to be shrink fit with applied heat. The material is formulated to break down at temperatures slightly below the expected downhole temperatures so that ideally the packer has about 48 hours of swelling delay which is normally a time period long enough to allow it to be properly located without it swelling so much as to cause it to be damaged by running in. Various polymers can be used to make an imperious covering for run in that on the way starts to break down. Ideally the material for the cover disappears about the time of sealing or shortly thereafter.

    摘要: A liner rotates a bit to make more hole. The liner has openings with inserts in them to lend torque resistance to the liner. The inserts have a passage with a send control media in the passage and a seal so that the liner can hold pressure for run in to get proper circulation through the bit. When sufficient hole is made, the liner is hung off an existing cemented tubular and the seal for the passages with the sand control media is removed by a variety of techniques so that the formation can be produced in a single trip.

    摘要: Casing or other well tubulars that have failed are repaired in a manner that doesn't reduce the final inside diameter and doesn't further propagate the failure. The tubular needing repair is first expanded on at least one zone above and below the damaged area. This expansion in an undamaged area arrests failure propagation when the damaged area is then expanded. After the damaged area is expanded, the patch coupled preferably with exterior seals is positioned in the expanded zone of the damaged tubular and expanded. The procedure can also be accomplished in a single trip into the well.

    摘要: A packer or plug features a main sealing element that swells after a delay long enough to get it into proper position. A sleeve eventually goes away to let the well fluids at the main sealing element to start the swelling process until contact with the surrounding tubular or the wellbore is established. Other sleeves that are disposed above and below the main sealing element preferably swell, but mainly in a longitudinal direction against the main sealing element to increase its contact pressure against the surrounding tubular or the wellbore. The longitudinally swelling members may also be covered to initiate their growth after the main sealing element has started or even completed its swelling action. The longitudinally swelling members can be constrained against radial growth to direct most or all of their swelling action longitudinally. Extrusion barriers above and below the main sealing element can optionally be used.

    摘要: A trigger device keeps a downhole tool from setting until it is properly positioned. Regardless of the type of tool or the type of associated trigger, the retainer of the present invention is combusted. The material is preferably one that combusts readily such as a material used in fuses for explosives. The battery requirements are to simply create the brief spark that starts the combustion, making the battery size significantly smaller than what would be needed to power a heater to melt materials that were used in the past.
