    Over the last years HDD wells are more and more popular as a trenchless method of disposing underground utilities. The number of works adapted or designed for HDD technology is growing very fast. One of the most important elements safeguarding the success of the performed operations is the rational selection of drilling tools. When choosing them one should account for a number of factors, e.g. price of the tool, availability, compatibility with other subassemblies and the rig itself. Erroneously selected tools may result in drilling complications, even failure to perform the undertaken tasks. No codification of drilling tools used for HDD wells was made as this is a case for cogged or diamond bits, i.e. IADC code. Therefore, the authors concentrated on working out guidelines for a rational selection of drilling tools for the HDD technology. Basing on the analyses and studies, the authors elaborated a computer program Horizon aiding the selection of the drilling tool.
