Theoretical Progress in the Exploration and Development of Deep Coal-Measure Gas

Dear Colleagues,

The drainage of coal-measure gas, represented by deep coalbed methane, has made significant progress. The daily production of deep coalbed methane in the Ordos Basin of China has exceeded 100000 m³/d, indicating that its development has excellent prospects. The purpose of this Special Issue is to summarize the current theory of deep coalbed methane accumulation and enrichment and clarify the respective laws. Meanwhile, due to the accuracy of the instruments currently used as well as the high temperature and pressure conditions, the physical parameters of deep coal seams cannot be directly obtained. Therefore, this Special Issue aims to summarize and clarify methods for predicting and evaluating the physical and gas properties of deep coal reservoirs and seams. In addition, advanced theories of deep coalbed methane development technology require summation.

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 submissions that pass pre-check are 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. Processes 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 2400 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.
