Centek Centralizer | Correct spacing program leads to no channeling for Conoco Phillips THE CHALLENGE Severe channeling and only 38% stand-off was found when using 1 traditional bowstring centraliser for every 4 joints. By running through a series of different cases in iCem Tim Groff, Sr. Account representative at Halliburton for cementing in the Rockies, identified that the centralizer program was inadequate. THE SOLUTION Halliburton recommended that Conoco Philips use 1 Centek S2 centraliser per joint through the curve and 1 every other joint in the vertical. THE RESULT Centralization was optimized for mud removal through critical zones and centralizers are run according to engineered design. The added cost of centralizers was offset by reduced drag which went from 40,000lb to 22,000lb.
