1     Other venting sources—mud degassing  Section 6.2.1

3.46B  Method 4—vented emissions from natural gas well completions, well workovers, cold process vents and well blowouts
  Method 4 is, for natural gas well completion activities, well workovers, cold process vents and well blowouts, as described in section 5.7.1 of the API Compendium.

Division 3.3.3—Crude oil production

Subdivision 3.3.3.1—Preliminary

3.47  Application
 (1) This Division applies to fugitive emissions from crude oil production activities, including emissions from flaring, from:
 (a) an oil wellhead; and
 (b) well servicing; and
 (c) oil sands mining; and
 (d) shale oil mining; and
 (e) the transportation of untreated production to treating or extraction plants; and
 (f) activities at extraction plants or heavy oil upgrading plants, and gas reinjection systems; and
 (g) activities at upgrading plants and associated gas reinjection systems.
 (2) For paragraph (1)(e), untreated production includes:
 (a) well effluent; and
 (b) emulsion; and
 (c) oil shale; and
 (d) oil sands.

Subdivision 3.3.3.2—Crude oil production (non‑flared)—fugitive leak emissions of methane

3.48  Available methods
 (1) Subject to section 1.18, for estimating fugitive emissions of methane, other than fugitive emissions of methane specified in subsection (1A), during a year from the operation of a facility that is constituted by crude oil production, one of the following methods must be used:
 (a) method 1 under section 3.49;
 (b) method 2 under section 3.50;
 (c) method 3 under section 3.51.
Note: There is no method 4 for this Division.
 (1A) For subsection (1), the following fugitive emissions of methane are specified:
 (a) fugitive emissions from oil or gas flaring;
 (b) fugitive emissions that result from system upsets, accidents or deliberate releases from process vents.
 (2) However, for incidental emissions another method may be used that is consistent with the principles in section 1.13.

3.49  Method 1—crude oil production (non‑flared) emissions of methane
 (1) Method 1 is:

where:
Eij is the fugitive emissions of methane (j) from the crude oil production during the year measured in CO2‑e tonnes.
Σk is the total emissions of methane (j) measured in tonnes of CO2‑e and estimated by summing up the emissions released from all of the equipment of type (k) specified in column 2 of the table in subsection (2), if the equipment is used in the crude oil production.
Qik is the total of the quantities of crude oil measured in tonnes that pass through each equipment of type (k) specified in column 2 of the table in subsection (2) during the year, if the equipment is used in the crude oil production.
EFijk is the emission factor for methane (j) measured in tonnes of CO2‑e per tonne of crude oil that passes through each equipment of type (k) specified in column 2 of the table
