ABSTRACT:
A centraliser has been developed which in one aspect an upper ring and a lower ring connected by six rigid members. The centralizer can be mounted on casing to be lowered down deviated bores. The rigid members are designed to collapse under a lateral load of about 20 tonnes. Thus if, for example, part of the bore collapses and the casing has to be withdrawn the rigid members will collapse enabling the centralizer to be recovered on the casing, preferably in one piece.
