Abstract
Drag-enhancing structures for downhole operations are included in a downhole assembly that further includes a tool string, extends past a maximum transverse perimeter of the tool string, and increases resistance to fluid flow past the downhole assembly when the downhole assembly is pumped in a downhole direction within a wellbore conduit. The systems and methods include conveying the downhole assembly in the downhole direction within the wellbore conduit. The systems and methods further may include decreasing the resistance to fluid flow past the downhole assembly after the downhole assembly is located within a target region of the wellbore conduit and/or flowing a sealing material past the downhole assembly while the downhole assembly is located within the wellbore conduit.
