Motivations: It is estimated that the forecasted methane resources of Russia's main coal basins contain 83.7 trillion cubic meters, representing roughly one-third of the country's natural gas reserves, but the production of CBM is rather small. So the bibliometric analysis of worldwide scholarly researches on this topic is rather actual.
Objectives: analysis of bibliometric data from recourses: SPE search, OnePetro, Dimensions, Lens and Scopus on topic "Coalbed methane". This research could be used as shot tutorial for bibliometric analysis of different publications DBs
Base query: ((TITLE-ABS-KEY("Coal bed Methane" OR "Coalbed Methane" OR "coal seam gas") AND LANGUAGE(English)) AND DOCTYPE(article OR conference paper) AND PUBYEAR > 2014)
