comments: RIH with 9 5/8" tie-back casing from surface to 374 m MD. Observed high thread torque on several joints.Observed some dry boxes. Had to lay out joint #57, #52 and #48 due to 70% thread torque on JAM unit and damaged threads. Used contingency dope LubeSeal API mod as required on pin end  after joint #48. Average running speed less 4 jnts/hr.
