CSA Z341 SERIES:22

Preface 

This is the sixth edition of CSA Z341 Series, Storage of hydrocarbons in underground formations , which consists of CSA Z341.1, Reservoir storage, CSA Z341.2, Salt cavern storage, and CSA Z341.4, Salt cavern waste disposal. It supersedes the previous editions published in 2018, 2014, 2010, 2006, and 2002. It also replaces CSA Z341, published as a single Standard in 1998 and 1993. 

This Series of Standards covers the storage of hydrocarbons and wastes from hydrocarbon production in naturally formed geological reservoirs and solution-mined salt caverns. This Series is intended to establish essential requirements and minimum standards for the design, construction, operation, maintenance, abandonment, and safety of underground storage systems. 

Users are reminded that this Series is not a design handbook; it is necessary to exercise competent engineering judgment in conjunction with its use. Major revisions to this edition are found as follows: 

a) CSA Z341.1: 

  i) Clause 7.5 (cased hole integrity inspection); 

  ii) Clause 8.2.2 (wellhead size); 

  iii) Clause 8.3.3 (ESV requirements); 

  iv) Clause 9.1 (pre-commissioning pressure test); 

  v) Clause 9.2 (pre-commissioning integrity inspection); 

  vi) Clause 9.5 (corrosion control); 

  vii) Clause 10.1.2 (emergency response plan);

  viii) Clause 10.2 (inspections and testing); 

  ix) Clause 12.3 (emergency planning); and 

  x) Annex A (updates reflecting changes to the clauses above). 

b) CSA Z341.2: 

  i) Clause 1.1 (scope);

  ii) Clause 5.1 (risk assessment);

  iii) Clause 5.6 (operation limits);  

  iv) Clause 7.2 (core acquisition); 

  v) Clause 7.5 (cased hole integrity inspection); 

  vi) Clause 8.2 (wellhead and Christmas tree assembly pressure rating);

  vii) Clause 8.3 (emergency shutdown valves); 

  viii) Clause 9.3 (cavern commissioning); 

  ix) Clause 9.4 (corrosion control);

  x) Clause 10.1 (procedures); 

  xi) Clause 10.2 (inspections and testing); 

  xii) Clause 11.1 (inventory verification); 

  xiii) Clause 12.3 (emergency planning);

  xiv) Clause 13.2.1 (preparation for stabilization period); 

  xv) Annex A (updates reflecting changes to the clauses above); and 

  xvi) Annex C (guidelines for mechanical integrity testing of storage caverns). 

c) CSA Z341.4: 

  i) Clause 1.1 (scope); 

  ii) Clause 5.1 (risk assessment); 

  iii) Clause 5.6 (operation limits); 

  iv) Clause 7.3.17 [(casing) pressure testing - field]; 

  v) Clause 7.5 (cased hole integrity inspection); 

  vii) Clause 8.3 (emergency shutdown valves); 

  viii) Clause 9.3 (cavern commissioning); 

  ix) Clause 9.4 (corrosion control); 

  x) Clause 10.1 (procedures); 

  xi) Clause 10.2 (inspections and testing); 

  xii) Clause 12.3 (emergency planning); 

  xiii) Clause 13.2.1 (preparation for stabilization period); 

  xiv) Annex A (updates reflecting changes to the clauses above); and 

  xv) Annex C (guidelines for mechanical integrity testing of waste disposal caverns). 

Annex A in each Standard provides commentary that complements and clarifies the clauses of CSA Z341.1, CSA Z341.2, and CSA Z341.4. The requirements of this Series are adequate under conditions normally encountered in the storage industry. Requirements for abnormal or unusual conditions are not specifically addressed, and complete details of engineering and construction are not provided. It is intended that all work performed within the scope of this Series will meet or exceed the safety standards expressed or implied in the Series. It is possible that changes will have to be made based on new experience or technology, or both. When necessary, amendments will be issued by CSA.

CSA Z341.1:22 -Reservoir storage 

Scope 

1.1 This Standard sets out minimum requirements for the design, construction, operation, maintenance, abandonment, and safety of hydrocarbon storage in underground reservoir formations and associated equipment. The equipment considered includes a) storage wellhead and Christmas tree assemblies; b) wells and subsurface equipment; and c) safety equipment, including monitoring, control, and emergency shutdown systems. Note: Hydrocarbons covered by this Standard are restricted to natural gas. 

1.2 The scope of this Standard is shown in Figure 1. 

1.3 This Standard does not apply to a) underground storage facilities for gases or fluids other than hydrocarbons, such as storage facilities used for air storage, unless the
