Abstract
An internally tapered production shoe for securing to the bottom of production tubing having no sharp projections, thereby permitting the removal of wireline tools from an initial location below the shoe without snagging. The shoe is particularly useful for slanted boreholes. The wireline tool being carried by a wheeled locomotive further minimizes attendant friction problems.
