About Flaring, Venting, and Fugitives

Flares are now monitored routinely from local, site-based sensors to aircraft and satellites. This is driven by ever-increasing societal pressure to eliminate routine and continuous flaring. Flaring is typically grouped in three defined categories: (i) routine flaring, (ii) safety flaring; and (iii) non-routine flaring.

  • Routine flaring of gas at oil production facilities is flaring during normal oil production operations in the absence of sufficiently sized facilities, offtake via pipeline, or amenable geology to re-inject. The World Bank has a goal to eliminate routine flaring by 2030, and many IOGP Member Companies have targets or aspirations related to flaring and venting.
  • Safety flaring of gas is flaring to ensure safe operation of the facility.
  • Non-routine flaring of gas is all flaring other than routine and safety flaring.

What does good look like?

  • Design flareless facilities whenever possible (within economic and technical limits).
  • No routine flaring of associated gas while producing oil.
  • Minimize any continuous and non-routine flaring in operations.
  • Design and operate facilities to minimize safety flaring.
  • Vents containing methane and hydrocarbons should be eliminated in support of managing GHG and fugitive emissions.

IOGP 647. Guidelines for the design and operation of flare gas recovery systems

Guidelines for the design and operation of flare gas recovery systems

These Guidelines focus on continuous flaring sources in normal operations and address measures for source recovery, flare closure, and flare ignition. This Report has been developed to assist engineering and operations staff at production, refining, and petrochemical owners and operators, and engineering staff at design consultancies and at engineering, procurement, and construction contractors.

Guidelines for design and operations to minimize and avoid flaring

This Report offers guidance for the design and implementation of solutions to assist the upstream oil and gas industry in minimizing or eliminating flared gas sources and volumes throughout the lifecycle of their assets. This Report can be used as a technical supplement to IOGP-Ipieca-GGFR Report 467 – Flaring management guidance.

IOGP 675. Guidelines for venting minimization and vent recovery systems

Guidelines for the design and operation of vent recovery systems and venting minimization

This guideline identifies venting sources and discusses the design and operation of vent systems and Volatile Organic Compound (VOC) recovery systems, as well as the situations in which these systems can be employed to minimize venting. This guidance has been developed to assist engineering and operations
staff at upstream production facilities and may be useful to midstream and downstream owners and operators, engineering staff at design consultancies, and engineering, procurement, and construction contractors.

IOGP 673. Guidelines for design and operations to minimize and avoid flaring

Flaring Management Guidance

This guidance details new flaring management and reduction developments, and examines industry experiences with eliminating flaring, new technologies, business models, operational improvements and regulatory policy. It also features case studies and examples of positive change, showing how governments and companies have reduced flaring and put the gas to productive use.

Zero Routine Flaring by 2030 (ZRF)

Launched in 2015, the ZRF Initiative commits governments and oil companies, to end routine flaring no later than 2030. The Initiative aims to support cooperation between all relevant stakeholders so that solutions to gas flaring can be found through appropriate regulation, application of technologies, and financial arrangements.

API 521 – Pressure-relieving and Depressuring Systems

This standard applies to pressure-relieving and vapor depressuring systems. Although intended for use primarily in oil refineries, it is also applicable to petrochemical facilities, gas plants, liquefied natural gas (LNG) facilities, and oil and gas production facilities. The information provided is designed to aid in the selection of the system that is most appropriate for the risks and circumstances involved in various installations. This standard specifies requirements and gives guidelines for the following: examining the principal causes of overpressure; determining individual relieving rates; selecting and designing disposal systems, including such component parts as piping, vessels, flares, and vent stacks.

API 537 - Flare Details for Petroleum, Petrochemical, and Natural Gas Industries

This standard specifies requirements and provides guidance for the selection, design, specification, operation, and maintenance of flares and related combustion and mechanical components used in pressure-relieving and vapor depressurizing systems for petroleum, petrochemical, and natural gas industries. While this standard is primarily intended for onshore facilities, guidance related to offshore applications is included. Annexes A through D provide further guidance and best practices for the selection, specification, and mechanical details for flares and on the design, operation, and maintenance of flare combustion and related equipment. Annex E explains how to use the data sheets provided in Annex F; it is intended that these data sheets be used to communicate and record design information.
