As of insert date, the company has completed the drilling of 138 vertical wells. Since the company undertook its project as the general contractor in Kazakhstan in 2009, we have proved capable enough to drill the wells at the highest speed and lowest cost with the existing tools and technical conditions as a result of our rich experience in the optimization of bottomhole drilling tool assembly and drilling parameters. We have been particularly successful in terms of well deviation control and wellbore wall stabilization. We have also cooperated with internationally renowned service companies to achieve particularly fast and straight vertical drilling with the use of world-class downhole tools and well deviation control techniques.
