   Standard DS-1® Fourth Edition

A lot has changed in our industry since we introduced the first edition of DS-1 in 1992. Drilling technology has advanced dramatically in twenty years, and to keep pace with this change T H Hill has continually updated Standard DS-1. The initial one volume of the first edition has evolved into the four volumes of Fourth Edition, covering drill string manufacture, design, inspection and specialty tools. Additionally, DS-1 has achieved global acceptance, as evidenced by its use in more than 60 countries and the incredible growth of the sponsor group.
