Canada Oil and Gas Geophysical Operations Regulations — 2
2 In these Regulations, Act means the Canada Oil and Gas Operations Act ; ( Loi ) complement , in respect of a vessel or platform from which an offshore geophysical operation is conducted, means all persons on the vessel or platform whose primary duties relate to the operation of the vessel or platform; ( équipage ) conservation officer means the person appointed as such pursuant to section 53 of the Act; ( agent du contrôle de l’exploitation ) explosive has the same meaning as in section 2 of the Explosives Act ; ( explosif ) geophysical crew means all persons engaged in a geophysical operation, but does not include any member of the complement; ( équipe d’étude géophysique ) geophysical operation means the measurement or investigation, by indirect methods, of the subsurface of the earth for the purpose of locating oil or gas or of determining the nature of the seabed and subsurface conditions at a proposed drilling site or of a proposed pipeline route, and includes a seismic survey, resistivity survey, gravimetric survey, magnetic survey, electrical survey and geochemical survey and any work preparatory to that measurement or investigation, such as field tests of energy sources, calibration of instruments and cable ballasting, but does not include a velocity survey or a vertical seismic survey that is not a walkaway vertical seismic survey; ( étude géophysique ) geophysical operation authorization means an authorization issued pursuant to paragraph 5(1)(b) of the Act to conduct a geophysical operation; ( autorisation d’étude géophysique ) gravimetric survey means a geophysical operation that measures the properties of the earth’s gravitational field; ( étude gravimétrique ) interest has the same meaning as in section 2 of the Canada Petroleum Resources Act ; ( titre ) magnetic survey means a geophysical operation that measures the properties of the earth’s magnetic field; ( étude magnétique ) non-exclusive survey means a geophysical operation that is conducted to acquire data for the purpose of sale, in whole or in part, to the public; ( étude non exclusive ) offshore geophysical operation means a geophysical operation that is not an onshore geophysical operation; ( étude géophysique extracôtière ) onshore geophysical operation means a geophysical operation that is conducted on or over land not normally submerged or on or over ice; ( étude géophysique sur terre ) operator means a person who holds a geophysical operation authorization; ( exploitant ) participant means a person who is a party to an agreement pursuant to which a participation survey is conducted; ( participant ) participation survey means a geophysical operation that is conducted by an operator pursuant to an agreement between the operator and one or more participants to acquire data that are to be shared among the participants; ( étude en participation ) seismic energy source means an energy source that is used to generate acoustic waves in a seismic survey; ( source d’énergie sismique ) seismic survey means a geophysical operation that uses a seismic energy source to generate acoustic waves that propagate through the earth, are reflected from or refracted along subsurface layers of the earth, and are subsequently recorded; ( étude sismique ) shotpoint means the surface location of a seismic energy source. ( point de tir )
