Special Issue Information

Dear Colleagues,

Because combusted natural gas generates less carbon dioxide per unit energy produced than coal or oil, transition to natural gas for energy generation presents a potential reduction in climate impacts. However, this benefit depends on low system leakage rates, as methane, the primary component of natural gas, is a potent greenhouse gas (GHG). The recent shale gas boom has resulted in significant focus on the GHG footprint of natural gas exploration and production.

The assessment of GHG impacts from natural gas extraction continually changes as rates of development increase or decrease, operators adopt new technologies and mitigation strategies, and regulatory actions are implemented. Measurements and subsequent models can lead to improved GHG emissions monitoring and mitigation strategies, and better estimates for life cycle analysis of GHG emissions from the natural gas value chain. These inventories and models provide the assessments on which climate change policy and regulatory actions are based.

This Special Issue invites critical reviews and research papers that analyze and discuss GHG emissions from natural gas systems. Specific emphasis is on (i) measurements from production and infrastructure components, (ii) their impact on regional air quality, (ii) climate change implications, and (iii) the effect of mitigation strategies and/or regulatory policies.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Environments is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

A variety of liquid unloading techniques are used to clear accumulated liquids from the wellbore to increase production rates for oil and gas wells. Data from national measurement studies indicate that a small subset of wells with plunger lift assist, that vent with high frequency and short event duration, contribute a significant fraction of methane emissions from liquid unloading activities in the United States. Compared to direct measurement of emissions at 24 wells in a field campaign, the most commonly used engineering emission estimate for this source category, which is based on the volume of gas in the wellbore, does not accurately predict emissions at the individual well (R2 = 0.06). An alternative emission estimate is proposed that relies on the duration of the venting activity and the gas production rate of the well, which has promising statistical performance characteristics when compared to direct measurement data. This work recommends well parameters that should be collected from future field measurement campaigns that are focused on this emission source. Full article
