Abstract
A circulation test tool and method of performing a circulation test in a wellbore during single-trip casing cutting and removal. An anchor mechanism (), a mechanical-set retrievable packer () and a cutting mechanism () allow gripping and cutting of casing () with the mechanical set-retrievable packer () being set after the cut to carry out the circulation test. The well is kept under control during the cut by application of tension on the drill string to set the packer () at any time. The arrangement provides full annulus flow pass at the packer during cutting. Embodiments describe additional features of a drill to dress a cement plug or a settable bridge plug.
