A fluid diverter tool, system and method of diverting a fluid flow in a in a well, having: a tubular mandrel and a packer element affixed onto an exterior thereof and operable to sealingly engage an inside of a pipe body to divert a flow of a treatment fluid outwards through holes formed in the pipe bod; and a pressure relief device operable to open and relieve pressure from one side to another side of the packer element when exposed to a given pressure differential acting across the pressure relief device from said one side of the packer element, the pressure relief device also adapted to close when exposed to a lower than said given pressure differential acting thereacross from said one side of the packer element.

Fluid diverter tool, system and method of diverting a fluid flow in a well

A method is for isolation of a permeable zone in a subterranean well, wherein the well is provided with a pipe body. The method comprises lowering a perforation tool into the pipe body; forming holes in the pipe body along a longitudinal section; pumping a flushing fluid out through outlets in a flushing tool, into the pipe body and further out into an annulus; pumping a fluidized plugging material out through the flushing tool, into the pipe body and further out into the annulus; placing the fluidized plugging material along the longitudinal section so as to form a plug across the cross section of the well, whereby the plug fills the pipe body and the annulus; wherein at least one outlet in the flushing tool is angled non-perpendicularly relative to a longitudinal axis of the flushing tool, whereby a corresponding discharge jet also will be non-perpendicular to the longitudinal axis.

Method for isolation of a permeable zone in a subterranean well

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.
