Canada Oil and Gas Drilling and Production Regulations (SOR/2009-315)

37. The operator shall ensure that pressure control equipment associated with drilling, coil tubing, slick line and wire line operations is pressure-tested on installation and as often as necessary to ensure its continued safe operation.

38. If the well control is lost or if safety, environmental protection or resource conservation is at risk, the operator shall ensure that any action necessary to rectify the situation is taken without delay, despite any condition to the contrary in the well approval.

39. The operator shall ensure that the well and casing are designed so that

• (a) the well can be drilled safely, the targeted formations evaluated and waste prevented;

• (b) the anticipated conditions, forces and stresses that may be placed upon them are withstood; and

• (c) the integrity of gas hydrate and permafrost zones — and, in the case of an onshore well, potable water zones — is protected.

40. The operator shall ensure that the well and casing are installed at a depth that provides for adequate kick tolerances and well control operations that provide for safe, constant bottom hole pressure.

41. The operator shall ensure that cement slurry is designed and installed so that

• (a) the movement of formation fluids in the casing annuli is prevented and, where required for safety, resource evaluation or prevention of waste, the isolation of the oil, gas and water zones is ensured;

• (b) support for the casing is provided;

• (c) corrosion of the casing over the cemented interval is retarded; and

• (d) the integrity of gas hydrate and permafrost zones — and, in the case of an onshore well, potable water zones — is protected.

42. After the cementing of any casing or casing liner and before drilling out the casing shoe, the operator shall ensure that the cement has reached the minimum compressive strength sufficient to support the casing and provide zonal isolation.

43. After installing and cementing the casing and before drilling out the casing shoe, the operator shall ensure that the casing is pressure-tested to the value required to confirm its integrity for maximum anticipated operating pressure.

44. The operator shall ensure that the production tubing used in a well is designed to withstand the maximum conditions, forces and stresses that may be placed on it and to maximize recovery from the pool.

45. The operator shall ensure that

• (a) operations such as processing, transportation, storage, re-injection and handling of oil and gas on the installation are effectively monitored to prevent incidents and waste;

• (b) all alarm, safety, monitoring, warning and control systems associated with those operations are managed to prevent incidents and waste; and

• (c) all appropriate persons are informed of the applicable alarm, safety, monitoring, warning or control systems associated with those operations that are taken out of service, and when those systems are returned to service.
