Abstract
Systems and methods of the present disclosure relate to wellbore scraping operations. A method comprises running a scraper tool into a wellbore with blades retracted; dropping a ball into an expandable seat of the scraper tool to build pressure; pumping fluid into the scraper tool to deploy a mandrel to compress a spring to rotate a j-slot to a second position from a first position to extend the blades; building pressure until the ball is released from the expandable seat; and moving the mandrel to a third position on the j-slot to lock the extended blades in place.
