Abstract
A treatment system including a settable and unsettable seal sub, an operation sub connected to the seal sub, the operation sub including a flow restrictor, and a selectively openable port biased to a closed position. A borehole system including a slickline, and a resettable seal connected to the slickline and runnable in the borehole on the slickline. A method for treating a formation adjacent a borehole including running the treatment system on a slickline to a target depth, flowing past the flow restrictor thereby causing the flow restrictor and a mandrel upon which the restrictor is mounted to move toward the seal sub, partially setting the seal sub and increasing pressure on the seal sub thereby fully setting the seal sub. A borehole system, including a borehole in a subsurface formation, a treatment system disposed within the borehole.
