Aerial And Ground-Based Optical Gas Imaging Survey Of Uinta Basin Oil And Gas Wells, Seth N. Lyman, Trang Tran, Marc L. Mansfield, Arvind P. Ravikumar

Bingham Research Center

We deployed a helicopter with an infrared optical gas imaging camera to detect hydrocarbon emissions from 3,428 oil and gas facilities (including 3,225 producing oil and gas well pads) in Utah’s Uinta Basin during winter and spring 2018. We also surveyed 419 of the same well pads from the ground. Winter conditions led to poor contrast between emission plumes and the ground, leading to a detection limit for the aerial survey that was between two and six times worse than a previous summertime survey. Because the ground survey was able to use the camera’s high-sensitivity mode, the rate of detected …

Quantifying Methane Emissions In The Uintah Basin During Wintertime Stagnation Episodes, C. S. Foster, Erik T. Crosman, J. D. Horel, Seth Lyman, B. Fasoli, R. Bares, J. C. Lin

Bingham Research Center

This study presents a meteorologically-based methodology for quantifying basin-scale methane (CH₄) emissions in Utah’s Uintah Basin, which is home to over 9,000 active and producing oil and natural gas wells. Previous studies in oil and gas producing regions have often relied on intensive aircraft campaigns to estimate methane emissions. However, the high cost of airborne campaigns prevents their frequent undertaking, thus providing only daytime snapshots of emissions rather than more temporally-representative estimates over multiple days. Providing estimates of CH₄ emissions from oil and natural gas production regions across the United States is important to inform leakage rates …

Analysis Of 2017 Multi-Agency Field Campaign Data For Wintertime Surface Pollution In The Cache Valley Of Utah, Gerardo Diaz Jr.

Masters Theses & Specialist Projects

Atmospheric motions resulting from rising airborne parcels help to scatter emissions, including PM, away from their sources, decreasing local pollution levels. However this pattern shifts during the wintertime, as cold air damming and inversion layers create stable conditions that limit the vertical transport of air masses. Both point and area sources of emissions currently dot the western United States and are responsible for the production of the vast majority of agricultural pollution in the region. At the same time, population-growth has resulted in an ever-increasing amount of urbansource emissions. The entrapment of PM, which are produced when a wide array …

Clean Energy And Climate Policy In Massachusetts, Dwayne Breger

Sustainability Education Resources

Over the past 20 years, Massachusetts has evolved as a leader in clean energy policy, which has led to market development, job and economic growth, and reductions in greenhouse gas and other emissions. This course will provide direct insights into the brief history of these policy developments, including policy objectives, legislative and regulatory roles, tradeoffs of costs and benefits, the use of analytical methods to establish program design, and stakeholder perspectives and engagement. The course will explore the market and economic development and challenges that have resulted from the policy, and explore the economic tradeoffs and distributional impacts that may …

Three Decades Of On-Road Mobile Source Emissions Reductions In South Los Angeles, Gary A. Bishop

Fuel Efficiency Automobile Test Publications

In May of 2018, the University of Denver repeated on-road optical remote sensing measurements at two locations in Lynwood, CA. Lynwood area vehicle tailpipe emissions were first surveyed in 1989 and 1991 because the area suffered with a large number of carbon monoxide (CO) air quality violations. These new measurements allow for the estimation of fuel specific CO and total hydrocarbon (HC) emissions reductions, changes in the longevity of emission-control components, and the prevalence of high emitters in the current fleet.

Since 1989 CO emissions decreased approximately factors of 10 (120 ± 8 to 12.3 ± 0.2 gCO/kg of fuel) …
