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.
