52 Restoration Currently BURINTEKH, Ltd performs restoration of produced tools. Rock destruction, milling and expandable tools are subject to repair. For defining the condition of tool and degree of repairing there are conducted estimative measures. Thread connection, body, main cutting structure and gage cutting structure are subject to evaluation. Elements of hardfacing, junk slot area and gage part are also evaluated. On the basis of received information the restoration works decision is made with discrepancy list. Restoration represents labourintensive process having much in common with manufacturing new tool. The device passes the same stages of reconstruction hard metal covering, installation of cutting structure and components. S pecial attention is paid to PDC cutting structure. By means of precise estimation specialists carefully make cutters scrapping ensuring qualitative restoration of cutting structure. 52

53 The condition of hardfacing of steel bits is estimated by its wear. The life time of the bit in consequence of increase of stability to mechanical and erosive wear depends on the full-rate restoration of surfacing. By means of surfaced layer the ability to sustain abrupt change of torque is increased. During the restoration of milling tools special attention is paid to application of wear resistant hard metal granulate because the quality of well milling depends on it. As far as restoration supposes additional thermal action it is conducted in a minimum of time to avoid undesired metal structural change. Matrix tools can be multiply restored. This feature allows extending the service life of tool and achieving higher rates. Restoration is the integral part of BURINTEKH, Ltd total output of products and provides customers with safe tools increasing costperformance ratio and decreasing the cost of well construction. 53

100 Torsional Jars SHOCK TURN W hy is stuck tool released by only up-and-down impacts along well axis? In fact, life experience suggests that for pulling, for example, driven nail out it is better not only pull it, but pull with simultaneous turn. Obviously, it is easier to free stuck downhole tool if not only axial impact loads but also shock torsion torque are applied. To solve this challenge, we developed torsional jars SHOCK TURN, which can affect stuck tool by clockwise and counterclockwise and up-and-down impacts in different combinations.
