Introduction of EzeeGlider® Low Friction Factor Centralisers in Russia

On two wells in the Arctic Region of Russia, Geoproteks centraliser program and recommendations help clients land 245mm (9 5/8”) casing in two high angle and long step out wells. The strings were +.- 5000m and over 5500m long in each well respectively and the latter with about 300m of air column. Both drilling rigs had been equipped with a casing drive system, which was however, not required in both cases. On Well nos.1 with 4800m of 245mm casing string, the effective string hook load at TD was about 105 T whilst on a previous well in the same field with a similar trajectory and well design, the available string weight (hook load) at 4200m was 48 T.
