Original Abstract Submitted
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.
