This is a dataset of oil and gas well pads which were surveyed for hydrocarbon emissions with an optical gas imaging camera deployed from the ground at pad edges.  The data are described thoroughly in a peer-reviewed paper:
Lyman S., Tran, T., Mansfield, M. Ravikumar, A., 2019. Aerial and Ground-Based Optical Gas Imaging Survey of Uinta Basin Oil and Gas Wells.  Under review for publication in Elementa.

The following is a description of the variables in the dataset:

pad_type: Type of pad.  OW signifies oil well and GW signifies gas well. Taken from Utah DOGM database (https://oilgas.ogm.utah.gov/oilgasweb/data-center/dc-main.xhtml)

well_count: Number of wells per pad.

pad_age: Age of pad to the nearest year (relative to March 2018). Derived from data available in the Utah DOGM database (https://oilgas.ogm.utah.gov/oilgasweb/data-center/dc-main.xhtml)

Indian_Country: "YES" signifies the pad is in Indian country.

Daily_oil_prod: Daily production of oil from the pad, in barrels, rounded to the nearest 50, in February 2018. Taken from Utah DOGM database (https://oilgas.ogm.utah.gov/oilgasweb/data-center/dc-main.xhtml)

Daily_gas_prod: Daily production of gas from the pad, in MCF, rounded to the nearest 100, in February 2018. Taken from Utah DOGM database (https://oilgas.ogm.utah.gov/oilgasweb/data-center/dc-main.xhtml)

2014_inventory: "YES" signifies the pad was included in the 2014 Utah air agencies oil and gas emissions inventory. (https://deq.utah.gov/legacy/destinations/u/uintah-basin/air-agencies-emissions-inventory/index.htm)

tank_controls: "YES" signifies the pad has emission controls installed on liquid storate tanks, if the pad is included in the 2014 inventory.

survey_date: Date the ground survey crew surveyed the pad.

temperature: Ambient air temperature in °C at the time of the survey.

wind_speed: Wind speed in m s-1 at the time of the survey.

solar_rad: Solar radiation in W m-2 at at the time of the survey.

sunny: Camera operator's assessment of whether it was sunny at the time of the survey.

dist_from_well: Distance in m of the camera from the well head.

dist_from_tank: Distance in m of the camera from the tanks on the well pad.

aerialsurve_detect: "YES" signifies that emissions were detected at this pad in the aerial survey.

num_plumes: Number of emission plumes detected on the pad by the aerial survey crew.

plume_size: Qualitative size of observed emission plumes, if available.

plume_source: source of the detected emission plume.
