Part are to be interpreted:
 (a) consistently with their accepted meaning in the oil and gas industry; and
 (b) where the term is relevant to methods in the API Compendium—taking into account the meaning and scope of the term in that compendium.
Note: In 2021, the API Compendium could be accessed at www.api.org.
 (2) If a method in this Part allows for the use of component or equipment emissions factors from the manufacturer of the component or equipment, those factors must not be used if they are likely to result in estimates of emissions inconsistent with the principles in section 1.13.

Division 3.3.2—Oil or gas exploration and development

Subdivision 3.3.2.1—Preliminary

3.42  Application
  This Division applies to fugitive emissions from venting or flaring from oil or gas exploration and development activities, including emissions from:
 (a) oil well drilling; and
 (b) gas well drilling; and
 (c) oil well completions; and
 (d) gas well completions; and
 (e) well workovers; and
 (f) well blowouts; and
 (g) cold process vents; and
 (h) mud degassing.

Subdivision 3.3.2.2—Oil or gas exploration and development (emissions that are flared)

3.43  Available methods
 (1) Subject to section 1.18, for estimating emissions released by oil or gas flaring during the year from the operation of a facility that is constituted by oil or gas exploration and development:
 (a) if estimating emissions of carbon dioxide released—one of the following methods must be used:
 (i) method 1 under section 3.44;
 (ii) method 2 under section 3.45;
 (iii) method 3 under section 3.46; and
 (b) if estimating emissions of methane released—one of the following methods must be used:
 (i) method 1 under section 3.44;
 (ii) method 2A under section 3.45A; and
 (c) if estimating emissions of nitrous oxide released—one of the following methods must be used:
 (i) method 1 under section 3.44;
 (ii) method 2A under section 3.45A.
Note: There is no method 4 under paragraph (a) and no method 2, 3 or 4 under paragraph (b) or (c).
 (2) However, for incidental emissions another method may be used that is consistent with the principles in section 1.13.

3.44  Method 1—oil or gas exploration and development
 (1) Method 1 is:

  Eij  = Qi  ×  EFij

where:
Eij is the fugitive emissions of gas type (j) from a fuel type (i) flared in the oil or gas exploration and development during the year measured in CO2‑e tonnes.
Qi is the quantity of fuel type (i) flared in the oil or gas exploration and development during the year measured in tonnes.
Note: This quantity includes all of the fuel type, not just hydrocarbons within the fuel type.
EFij is the emission factor for gas type (j) measured in tonnes of CO2‑e emissions per tonne of the
