摘要

An adaptor (64,66) has attachment means to releasably attach a core orientation instrument (60) or survey probe to a drill string component and/or drill string, preferably by one or more screw threads (70, 72, 76, 78), retaining screws, bolts, clips or pins or welding/soldering. Anti release means, such as a circlip, can be used to prevent release of the adaptor. A survey system for obtaining data from a drilling operation includes a core orientation instrument, a downhole survey probe and a common single remote controller/data logger configured to control or communicate with both the survey probe and the core orientation instrument. Further, a survey system includes multiple components arranged in a portable container for transport and deployment at a drilling site include a survey probe, a core orientation instrument and a single controller configured to control or communicate with the survey probe and core orientation instrument.
