Newfoundland Offshore Area Petroleum Geophysical Operations Regulations (SOR/95-334)

Regulations are current to 2015-10-27 and last amended on 2014-12-31. Previous Versions


Geophysical Operation Authorization

 Any person may apply for a geophysical operation authorization by submitting to the Chief Conservation Officer three copies of a completed application form.

 Subject to section 5, an application in respect of a geophysical operation shall be submitted not less than

  • (a) 30 days before the planned commencement date of the operation, if chemical explosives are not the proposed seismic energy source; and

  • (b) 90 days before the planned commencement date of the operation, if chemical explosives are the proposed seismic energy source.

  •  (1) An application to extend the duration for which a geophysical operation has been authorized shall be submitted at least 15 days before the end of the period being extended or, where the commencement date is being modified, the planned new commencement date.

  • (2) An application in respect of any modification of a geophysical operation that has been authorized, other than a modification of its duration, shall be submitted at least 15 days before the commencement of the geophysical operation or, where the geophysical operation has commenced, the start of the geophysical operation as modified.

 When a geophysical operation is commenced, terminated or cancelled by an operator, the operator shall forthwith notify the Chief Conservation Officer in writing of the date of commencement, termination or cancellation.

 Every operator shall post a copy of the geophysical operation authorization in a conspicuous location in the vessel, platform or aircraft from which the geophysical operation is conducted.

Damage to Property

 Every operator shall take all reasonable safeguards against damage to property as a result of the geophysical operation.


 Where a fire occurs as a result of a geophysical operation, the operator shall take all safe and reasonable measures to control and extinguish the fire and to minimize any danger to persons, property or the environment that results or may reasonably be expected to result from the fire.


 Subject to any other applicable law, every operator shall ensure that all refuse produced as a result of a geophysical operation is handled in the following manner:

  • (a) all fuel, oil, oily material or lubricants are collected in a closed system that is designed for that purpose;

  • (b) all oil or oily material that is not burned on a vessel or platform and all non-combustible material is transported in a suitable container to, and disposed of at, a suitable waste disposal facility on land; and

  • (c) where combustible material is burned on a vessel or platform, precautions are taken to ensure that the fire does not endanger any person or the safety of the vessel or platform.


Air Gun System

 Where an operator who is conducting a geophysical operation uses or intends to use an air gun as a seismic energy source, the operator shall ensure that

  • (a) all air gun components are maintained in good operating condition and are kept free from dirt, oil and excess grease;

  • (b) during the operation, the air vessels, air manifolds, air lines, electrical lines and the compressor of the air gun system are regularly inspected for signs of abrasion and wear, and that the compressor, where defective, and any defective air vessels are promptly repaired or replaced and any defective manifolds or lines are promptly replaced;

  • (c) all fittings, valves, hoses, electrical lines, pipes or other components used for an air gun comply with the manufacturer's specifications for that air gun;

  • (d) where there is air pressure in the air gun, the pressure is maintained as low as is practicable but sufficiently high to ensure that the air gun remains seated and that there is no danger of accidental firing;

  • (e) no maintenance of the air gun is carried out until

    • (i) the air pressure in the air gun and the air line connected to the air gun has been completely bled off, and

    • (ii) the shuttle of the air gun can be moved freely by use of a wooden safety tool to confirm that the air gun has been completely depressurized; and

  • (f) where more than one air gun is used as a seismic energy source, a procedure is established and followed for the connection of each air gun to its air line and pressure control valve.
