Non-API 10D type Centraliser/hole configuration for passage through previously installed casing into oversize/under

Note: Centek performance curve figures are corrected by deducting half the internal diameter clearance from the

vertical 'Y' axis to indicate true Standoff conditions

Note: It is strongly recommended that the Centek LatLoad program is utilised for each individual under-ream

situation to check acceptability of accumulative Start loads through previously installed tubulars.
