Methane venting from uncontrolled production storage tanks at conventional oil wells: Temporal variability, root causes, and implications for measurement
Emissions from uncontrolled oil production storage tanks are poorly understood and characterized. This study reports and analyzes directly measured, temporally varying methane emission rates, total gas vent rates, and vent gas methane fractions from storage tanks at eight active upstream oil production sites in Alberta, Canada. Detailed statistical analyses were completed to suggest minimum sampling […]
Reducing methane emissions: Best practice guide – pneumatic devices
This document provides best practices for reducing or eliminating methane emissions from pneumatic devices. The guide outlines methods such as replacing pneumatic devices with electrical or mechanical alternatives, using compressed air instead of natural gas, capturing vented gas, or switching to low-bleed devices. It also emphasizes regular inspections and repairs of devices with higher-than-expected emissions. […]

Flaring management guidance, developed by Ipieca, IOGP and GGFR in partnership, outlines new developments in flaring management and reduction, 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.
Reducing methane emissions: Energy use
This document provides guidance on reducing methane emissions from the use of natural gas as fuel in oil and gas operations. Methane slip, the unburned methane released from combustion engines, is a key emission source. While generally small, it can be significant in areas with high natural gas usage. The guide emphasizes best practices for […]
Methane exhaust measurements at US gathering compressor stations
This study measured methane emissions from internal combustion engines used in natural gas compression at U.S. gathering and boosting stations. Researchers sampled 133 engines from 67 facilities across 11 states. Using a in-stack tracer gas method, they estimated combustion slip (methane that escapes during the combustion process) under normal conditions. The data was then used […]
Where the methane is – insights from novel airborne LiDAR measurements combined with ground survey data
This study combines airborne LiDAR measurements, parallel controlled releases, and on-site optical gas imaging (OGI) survey and pneumatic device count data to derive a new measurement-based methane inventory for oil and gas facilities in British Columbia, Canada. Results reveal a surprising distinction between the higher magnitudes, different types, and smaller number of sources seen by […]
