DS-1^TM standard is a set of advanced drill string and its components manufacturing, design, inspection standards, the industry generally recognized, so far which has been adopted more than 60 countries and regions in the world. In the early period, lacking of down hole tool standard, as co-sponsors, T.H.Hill combined the other 12 operating companies which approve the necessity to set standard to participate this project. The first edition of DS-1 was published in 1992 and sold 16000 copies.

The second edition was published in 1998. The number of sponsors has developed into 37 including operating, renting and inspection companies. This edition was sold 10000 copies, which has become popular drilling tools specification and quality assurance standard in the world. From that time, engineering and technical staff of T.H.Hill followed developing step, then the third and forth editions were published, respectively. Published in 2012, the fourth edition includes new manufacture, inspection and design technique of specialty tools.

More and more people use the DS-1 Standard in China; however, there are so many differences in understanding and mastering. T.H.Hill decides to hold the first training class in Oct.17-19, 2016 in China. After the end of training, the DS-1 training certificate is issued by the T.H.Hill. As training co-organizer, our lab is responsible for organizing, noticing and assisting to develop this training, specific as follows:
