Patent number: 9739135Abstract: 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.Type: GrantFiled: January 17, 2013Date of Patent: August 22, 2017Assignee: Globaltech Corporation Pty Ltd.Inventors: Brett James Wilkinson, Michael Alan Klass, Johan Anwar, Khaled Hejleh, Gordon Stewart

Patent number: 9726007Abstract: A drillstring first tube portion (10) for connection to further tube portions (24,26) of a drillstring via respective connection means has a side wall (16) including non ferromagnetic material, and at least one downhole survey device (12) mounted directly or indirectly on or within the side wall. The survey device has at least one survey instrument to obtain survey data, a power source (22) and wireless communication means (18) to wirelessly receive and/or transmit survey data within or on the side wall. A method of conducting a downhole survey of drilling using such an apparatus is also disclosed, as well as a method of obtaining data gathered downhole. The survey device and a core orientation device (32) may communicate wirelessly, such as when passing each other.Type: GrantFiled: March 12, 2013Date of Patent: August 8, 2017Assignee: Globaltech Corporation Pty LtdInventors: Khaled Hejleh, Gordon Stewart, Brett James Wilkinson, Michael Alan Klass, Johan Anwar

Publication number: 20120176251Abstract: A drilling log data logger 10, and system incorporating the same, has means 14-40 to receive drilling event related data, electronic storage means to store said input data, and output means 12,42 to output said data on demand. A related drilling log data recordal method for at least one drilling operation includes entering 100 initial drilling data into a data logger 10, said initial drilling data relating to at least one said drilling operation, creating current progress drilling data 108 in the data logger based on said initial drilling data, entering subsequent drilling data 110 into the data logger relating to one or more of a drilling task, drilling progress, drilling equipment or drilling operators of said drilling operation, comparing the subsequent drilling data 110 with the current progress drilling data 108; and updating the current progress drilling data 108 using the subsequent drilling data 110.Type: ApplicationFiled: July 27, 2011Publication date: July 12, 2012Applicant: Globaltech Corporation Pty Ltd.Inventors: Michael Alan Klass, Brett James Wilkinson, Gordon Henderson Stewart, Khaled Mufid Yousef Hejleh, Johan Anwar
