Abstract
A shifting tool for sleeves is supported on wireline or slickline and is pumped to the desired location by pressure from above delivered against the tool and passing around its periphery or against an articulated peripheral extending member that can optionally seal. Once in the vicinity of the desired sleeve to be shifted the shifting key is engaged to the sleeve and further applied pressure on the articulated peripheral seal shifts the sleeve in a downhole direction. The sleeve can also be shifted in an uphole direction with an anchor that grabs near the sleeve and a latch key that grabs the sleeve and is configured to retain grip as a motor moves the latch key uphole. Power can come from a wireline or can be locally provided if using slickline. The seal or extending member is retractable for tool removal or relocation.
