67Directional and deviation surveys#
An operator must ensure that
(a)directional and deviation surveys are taken at intervals that allow the position of the well-bore to be accurately known during drilling;
(b)the directional and deviation surveys are adequate to permit the management, in relation to the well-bore, of identified geohazards, the intersection of the geological targets for the well and the intersection of the well-bore in the event that a relief well is required; and
(c)except in the case of a relief well, every well is drilled in compliance with internationally recognized well-bore collision avoidance practices and procedures and in a manner that does not intersect an existing well.
