A whipstock assembly and a method for side-tracking a wellbore. The whipstock assembly includes a casing sub-assembly. The casing sub-assembly has a first rotating collar, a second rotating collar, and multiple bars. The bars are movable from a first position spaced apart from the first and second rotating collars to a second position extending between the first rotating collar and the second rotating collar. The bars are rotatable from the second position to a third position to open a window in the bars and form a ramp oriented toward the window.

Side-tracking a wellbore

A through-tubing plug includes an outer mandrel defining a first uphole port and a first downhole port, an inner mandrel received within the outer mandrel and defining a second uphole port and a second downhole port, a plug core provided on the outer mandrel and providing a landing profile sealingly engageable with a landing receptor provided within completion tubing extended into a wellbore, and one or more sets of wipers made of a foam material and secured to the outer mandrel distal to the plug core. The inner mandrel is movable between an unactuated state, where the first and second uphole ports are misaligned and the first and second downhole ports are misaligned, and an actuated state, where the first and second uphole ports are aligned and the first and second downhole ports are aligned to thereby allow fluid flow through the through-tubing plug.

Systems and methods for cleaning and inspecting a wellbore. A wellbore cleaning tool has a jetting sub-assembly, a reverse circulation sub-assembly, and a guide shoe sub-assembly with a camera. The jetting sub-assembly has jetting nozzles oriented to direct a fluid at the wellbore. The reverse circulation sub-assembly has a barrel defining two inner voids fluidly decouplable from each other. The barrel has a first fluid port. A first set of outlet ports extend through the barrel from the one inner void to outside the wellbore cleaning tool. A second set of outlet ports extend through the barrel from the other inner void to outside the wellbore cleaning tool. The second fluid port controls fluid flow from outside the wellbore cleaning tool and the second inner void. A third fluid port controls fluid flow through the other inner void fluidly to the jetting sub-assembly.
