Energy and heat generation processes are required throughout the oil and gas value chain.
Leaks are the unintentional releases of natural gas from equipment used in oil and gas operations.
Reciprocating compressors (also referred to as piston compressors), are found in a variety of oil and gas operations.
Reconciliation is the process of comparing source-level (Level 4) inventories with independent site-level measurements to produce Level 5 asset emissions estimates.
When natural gas (NG) is released into the atmosphere, its impact over 20 years as a greenhouse agent is 80 times greater than CO₂.
In natural gas production wells, initial gas flow velocity is usually sufficient to entrain produced liquids as droplets and carry them up the well tubing and to a gas/liquid separator.
This document presents general principles which apply to all Technical Guidance Documents (TGDs), unless stated otherwise in the TGDs.
Incidents and emergency stops are unintended and unplanned events/venting which are not part of routine operations.
Venting is the intentional release of gas (or methane-containing vapors) to the atmosphere, typically required by the design, operation, construction and commissioning, or maintenance of the equipment.
Casinghead gas is gas that evolves off of crude oil when it flows into a lower pressure through well casing perforations and collects in the annular space between the casing and tubing in an oil well.
