摘要： A method of sealing a well comprises creating one or more openings in a tubing installed in a wellbore, in a location for a well seal; using a wireline to locate a stinger in that location; setting the stinger in that location; and forming a seal in the well in that location, by injecting sealant through said stinger.

摘要： A method of centralizing a tubing in a wellbore includes providing one or more expandable elements between the tubing and a surrounding casing located in a wellbore and expanding the expandable elements against the casing so as to cause the tubing to become centered within the casing. Alternatively, one or more portions of a tubing are expanded against a surrounding casing located in a wellbore so as to cause the tubing to become centered within the casing.

摘要： A method of plugging a well includes providing a tubing in a wellbore, wherein in a location for a well plug, the tubing is provided with an internal cable section placed inside of the tubing and/or an external cable section placed outside of the tubing, the external cable section including a fluid-tight cable suitable for forming a sealing part of the well plug, and forming a plug in the well in the location for the well plug without pulling the tubing from the wellbore.

摘要： There is provided a method for removing iron-containing casing from a well bore comprising providing a cathode in said well bore, wherein said cathode is connected to the negative pole of a power source; connecting said iron-containing casing to the positive pole of said power source; injecting an electrolyte into said well bore, wherein said electrolyte contacts said iron-containing casing and said cathode; applying a current so that the iron in said iron-containing casing is oxidised to iron cations; allowing said iron cations to dissolve in said electrolyte; and removing said electrolyte from said well bore. Also provided are a system for removing iron-containing casing from a well bore, a method for monitoring the removal of an iron-containing casing from a well bore and a method for plugging and abandoning a well.

摘要： A method of plugging a well extending into a formation to facilitate temporary or permanent abandonment of the well. The method comprises conveying in one trip, a plug assembly and one or more explosive charges through the well together with a structure for providing wet sealant. The plug assembly comprises a foundation plug for supporting the wet sealant. The plug assembly is set beneath a plug formation location, prior to providing the wet sealant. The method also comprises providing the wet sealant to the plug formation location via the structure, so as to submerge the one or more explosive charges in the wet sealant, and then detonating the one or more explosive charges in the wet sealant at the plug formation location to cut through a tubular or tubulars of the well and into the formation.
