Abstract
An apparatus for cutting a conduit in a borehole includes combustible material within a body; a nozzle comprising apertures; a support element between the nozzle and the combustible material, the support element comprising a mixing cavity within the support element; an activation device for igniting the combustible material to form a matrix of combustion products for passage toward the nozzle via the mixing cavity; and a swirl diverter comprising an outer surface having a plurality of helical vanes which extend from one end of the swirl diverter toward an opposite end of the swirl diverter. The apertures of the nozzle are configured to direct the matrix of combustion products from the mixing cavity to the helical vanes, and the helical vanes are shaped to rotate the matrix of combustion products and direct the matrix of combustion products radially outward of the body for cutting the conduit.
