57. The operator of a suspended well shall ensure that the well is monitored and inspected to maintain its continued integrity and to prevent pollution.

58. The operator shall ensure that, on the abandonment of any offshore well, the seafloor is cleared of any material or equipment that might interfere with other commercial uses of the sea.

59. No operator shall remove or cause to have removed a drilling installation from a well drilled under these Regulations unless the well has been terminated in accordance with these Regulations.

• 60. (1) Unless otherwise included in the approval issued under subsection 7(2), the operator shall ensure that the rate of flow and the volume of the following are measured and recorded:

  • (a) the fluid that is produced from each well;

  • (b) the fluid that is injected into each well;

  • (c) any produced fluid that enters, leaves, is used or is flared, vented, burned or otherwise disposed of on an installation, including any battery room, treatment facility or processing plant; and

  • (d) any air or materials injected for the purposes of disposal, storage or cycling, including drill cuttings and other useless material that is generated during drilling, well or production operations.

• (2) The operator shall ensure that any measurements are conducted in accordance with the flow system, flow calculation procedure and flow allocation procedure, approved under subsection 7(2).

• 61. (1) The operator shall ensure that group production of oil and gas from wells and injection of a fluid into wells is allocated on a pro rata basis, in accordance with the flow system, flow calculation procedure and flow allocation procedure approved under subsection 7(2).

• (2) If a well is completed over multiple pools or zones, the operator shall ensure that production or injection volumes for the well are allocated on a pro rata basis to the pools or zones in accordance with the flow allocation procedure approved under subsection 7(2).

62. The operator shall ensure

• (a) that meters and associated equipment are calibrated and maintained to ensure their continued accuracy;

• (b) that equipment used to calibrate the flow system is calibrated in accordance with good measurement practices;

• (c) that any component of the flow system that may have an impact on the accuracy or integrity of the flow system and that is not functioning in accordance with the manufacturer’s specifications is repaired or replaced without delay, or, if it is not possible to do so without delay, corrective measures are taken to minimize the impact on the accuracy and integrity of the flow system while the repair or replacement is proceeding; and

• (d) that a conservation officer is notified, as soon as the circumstances permit, of any malfunction or failure of any flow system component that may have an impact on the accuracy of the flow system and of the corrective measures taken.
