    摘要: Methods and tools to consolidate a wellbore by displacing conventional cement slurry or any other settable fluid, without any permanent casing are useful. A bladder is inflated inside the bore to act as a mold and to form an annulus that can be filled by cement slurry or any other settable fluid. When the cement or the resin is set, the form is retrieved by straight pull; leaving a cement or resin sheath to support the formation without requiring any re-drilling. The sheath can be perforated if necessary (in the producing zone). Applications include without limitations temporary cementation of mono-diameter wells, through-tubing repair of an open hole, or cementation of a slotted liner in water, oil or gas wells.

    摘要: A clean version of the revised Abstract is shown below for the Examiner's convenience.A method of and apparatus for treating a zone in a well is disclosed. A tube that is permeable to a material is inserted into a wellbore, creating an annulus inside the wellbore. Two zones—the annular region and the formation surrounding the wellbore—may be treated. The method comprises the following steps. (1) A setting section surrounded by a sleeve is placed inside the tube near the zone to treat, the sleeve being expandable and impermeable to the material. (2) The sleeve is inflated inside the tube near the zone to treat, ensuring that a first zone of the tube is impermeable to the material, but leaving a second zone permeable to the material. (3) A treatment fluid is pumped to the zone to treat, the treatment fluid passing into the annulus via the second zone. (4) The zone to treat is treated with the treatment fluid.

    摘要: A method of and an apparatus for treating a near zone and/or a far zone of a well is disclosed. The method comprises the following steps. (1) A tube that is permeable to a material is placed inside a wellbore, forming an annulus inside the wellbore. (2) A setting section surrounded by a sleeve is placed inside the tube. The sleeve is expandable and impermeable to the material. (3) The sleeve is inflated so that the sleeve is in contact with the tube, ensuring for a first zone of the tube is impermeable to the material, but leaving a second zone permeable to the material. (4) A treatment fluid is pumped to the zones that passes through the second zone still permeable to the material. (5) The near zone in the annulus and/or the far zone in the surrounding formation is treated with the treatment fluid.

    摘要: The external surface of a tubular body such as well casing is coated with a substance that, upon exposure to cement, is unstable and degrades. After installation in a subterranean well and subsequent cementation, the coating degrades and forms a gap between the external surface of the tubular body and the cement sheath. Forming the gap is useful for obtaining optimal stimulation during the hydraulic fracturing of unconventional shale-gas formations.

    摘要: Compositions containing an alkali swelling polymer and a pH buffer with a pH between 3 and 7 may be used to treat a wellbore. The pH buffer prevents the swelling of the alkali swellable polymer. The compositions may be placed in the wellbore, whereupon they contact another material with pH increasing properties. The pH of the compositions increases, causing the compositions to swell and form a seal. The alkali swelling polymer may be an alkali swelling latex.
