Abstract: A method is for establishing a new well path from an existing well, wherein the existing well, at least in a portion where the new well path is to be established, is delineated radially by a casing. The method comprises disposing and anchoring a plug base in the well; providing a plug above the plug base in the well and along a longitudinal section thereof, wherein the plug, at least in a portion thereof, covers substantially the entire cross-section of the well; removing a portion of the plug in such a manner that at least a cross-sectional section of the plug remains on the outside of the casing; disposing and anchoring a direction-guiding element in the well, and at least partially within the longitudinal section; and with the direction-guiding element, guiding a drilling tool against the inside of the casing in the existing well path in order to form a hole through the casing, and through the remaining cross-sectional section of the plug within the longitudinal section, which opens up to formation of a new well path. The method also comprises conducting a perforation tool down into the casing and to the longitudinal section where the plug is to be set; forming holes in the casing and along the longitudinal section by means of the perforation tool; and pumping a fluidized plugging material down through the string and out into the casing, thus also into the annulus via the holes in the casing.

Abstract: A method is for the combined perforation, cleaning, and the subsequent plugging of a longitudinal section of a well. The well is provided with two pipe bodies placed substantially concentrically. The method includes lowering a perforation tool into the innermost pipe body to the longitudinal section, forming perforations in both pipe bodies along the longitudinal section with the perforation tool, cleaning the longitudinal section with a flushing tool which is attached to a lower portion of a string allowing through-flow, pumping a fluidized plugging material down the string and into the innermost pipe body at the longitudinal section, and placing the fluidized plugging material in the innermost pipe body, and thereby also into the entire cross section of the well via the perforations within the longitudinal section. A flushing tool is for cleaning the longitudinal section of the well.

Abstract: A method is for establishment of a new well path from a well. The method comprises disposing and anchoring a plug base in a casing in the well; lowering a perforation tool into the casing; forming holes in the casing along a longitudinal section; pumping a flushing fluid out through outlets in a flushing tool and into the casing and further out into an annulus; pumping a fluidized plugging material out through the flushing tool and into the casing and further out into the annulus; placing the fluidized plugging material along the longitudinal section so as to form a plug across a cross section of the well; wherein the outlets in the flushing tool are angled non-perpendicularly relative to a longitudinal axis of the flushing tool. The method also comprises removing a portion of the plug until a cross-sectional section of the plug remains in the annulus; disposing and anchoring a direction-guiding element in the casing within the longitudinal section; by means of the element, guiding a drilling tool against the inside of the casing; and forming an exit hole through the casing and the cross-sectional section of the plug, thereby allowing a new well path to be formed from the well.
