TSS LLC's and Nefneyugansk SBU's specialists have successfully run a liner bearing MSZ BULAT LLC's PTsR.7.102/146 Cementing Hanger in Well 3516 of Pad 138 of the Prirazlomnoye Field (RN-Yuganskneftegaz LLC). The work was done as part of well revamping by the sidetracking method. The liner fitted with frac ball sleeves has been run in the hole and collar cementing was performed.
