Canada Oil and Gas Drilling and Production Regulations (C.R.C., c. 1517)

Regulations are current to 2020-11-02

Pipe Racks

 Pipe racks shall be substantially constructed and provision made to have the casing, drill pipe, drill collars and the like laid thereon adequately cleated to prevent them from rolling off the racks.


 When casing or drill pipes are being disconnected on drilling platforms, a metal guard that will prevent mud or water splashing on workmen shall be installed on every drilling rig.

Rotary Drilling Rig

  •  (1) On both sides of the draw works, guards of heavy metal shall be provided for all drive sprockets and chains, and such guards shall be strong enough to withstand the shock of breaking chains and shall be installed so that workmen cannot come in contact with the moving parts.

  • (2) The guard for the low gear drum driven sprockets and chain next to the driller shall be flanged with a steel plate so that a breaking chain cannot hit the driller or foul the brake lever.

  • (3) On every chain-driven rig, the pinion shaft, the couplings and the bevel gear shall be guarded with metal shields.

  • (4) On every shaft-driven rig, the drive pinion, the shaft, the coupling and the bevel gears shall be guarded with metal shields.

  • (5) The pump end of every rig hose shall be securely fastened to the derrick and the swivel end of such hose shall be securely fastened to the swivel housing with a safety chain or wire cable.

  • (6) The key seat and projecting key on every cathead shall be covered with a smooth thimble.

  • (7) Every cathead shall be provided with an adequate guard to separate the first turn of the catline.

  • (8) The tops and outer sides of the hoisting drum brake flanges shall be guarded by a steel plate of a thickness not less than 1/8 inch, and these guards shall be installed with a minimum working clearance from the brake and shall be securely bolted in place.

  • (9) All rotary rig tongs shall be provided with two separate wire-rope safety cables of a diameter not less than 5/8 inch.

  • (10) Every steam-driven drilling engine shall, in addition to the usual steam-control valve, be equipped with a quick closing steam valve to which is attached an extension handle of sufficient length so as to be readily available to the driller while at the controls of the rig.

  • (11) The rotary table shall not be used for final making up or initial breaking out of drill pipe.

  • (12) Where practicable, a locking device shall be installed on all control levers.

  • (13) The eye connection of all safety cables shall be securely fastened with at least three U type clamps.

  • (14) The suction pit shall be equipped on its outer edge with a two-rail railing of adequate height.

Rig Record Book

  •  (1) The owner of a drilling rig shall keep at the rig a hard covered book in which shall be entered information as required by sections 68, 83, 92 and 93.

  • (2) This book shall be readily available to the Oil Conservation Engineer at all times.

Draw Works Brakes

 The brakes on the draw works of every drilling rig shall be tested by each driller when he comes on shift to show whether they are in good order, and such brakes shall also be examined at weekly intervals by the tool-pusher or other person authorized by the owner of the rig, who shall enter the result of this examination in the Rig Record Book over his signature.

Hoisting, Casing or Rotary Drilling Lines

  •  (1) The end of the hoisting line shall be securely fastened to the hoist drum shaft.

  • (2) The hoisting line shall be long enough so that, when the travelling block is laid horizontally on the derrick floor, there will remain at least three turns of rope on the hoist drum.

  • (3) Every hoisting line used in well-drilling, well-servicing and well-abandoning operations shall be examined weekly by the toolpusher, or other person authorized by the owner to determine the condition of the line, who shall enter the result of his examination in the Rig Record Book over his signature.

  • (4) No hoisting line used for well-drilling, well-servicing or well-abandoning operations shall be used when the factor of safety falls below five.

  • (5) When the examination mentioned in subsection (3) indicates that any one or a combination of two or more of the following conditions may have reduced the safety factor to less than five, the line shall be replaced:

    • (a) worn wires;

    • (b) broken wires;

    • (c) visible corrosion; and

    • (d) a damaged or otherwise defective line.

  • (6) The ultimate strength of wire-rope hoisting lines should be based on the manufacturer’s catalogue.

First Aid

  •  (1) Every driller employed on a gas or oil well drilling rig shall be the holder of a certificate of competency in First Aid in good standing.

  • (2) Every employer shall provide and maintain at every drilling rig a suitable First Aid Kit of a recognized standard and a carrying stretcher.


 Cellars, after the setting and heading up of the surface casing, with the exception of those less than four feet deep or those in which a false flooring has been installed to make such cellar less than four feet deep, shall be provided with two runways constructed opposite each other, extending from the cellar bottom to the ground surface, but

  • (a) the slope of the runways shall not exceed 20 degrees from the horizontal;

  • (b) the width of the runways shall be not less than three feet in the clear;

  • (c) the clearance between the floor of each runway and the derrick sills shall be not less than seven feet;

  • (d) the cellar and cellar exit shall be secured against caving by the use of sheeting and shoring installed in a manner that will permit the unobstructed passage of employees; and

  • (e) the runways and their approaches shall be kept clear of snow or other material.

Storage of Explosives

 Except as otherwise provided by the Explosives Act, explosives shall be stored in properly constructed magazines at a distance not less than 500 feet from any place where any drilling or production operation is carried on.

Notice of Fatal Accident

 Where in or about any well any accident occurs which causes loss of life to any person employed thereat, the person in charge of such well shall immediately notify the Oil Conservation Engineer by telephone, telegraph or radio, and confirm by letter.

Operations Outside the Northwest Territories and Yukon Territory

 Subsections 15(4), (5) and (6) and sections 21, 31, 33 and 95 do not apply to drilling operations that are carried on outside the Northwest Territories or the Yukon Territory.
