It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.
The problem of reservoir engineering and production of coalbed methane (CBM) in Kazakhstan are important subject today. Identification of methane-rich zones from the coal geology side is not always enough. In this article, traditional methods for studying oil and gas basins are applied for identification of methane rich zones in southern part of Karaganda coal basin. Reservoir simulation is used to check the possible production performance of the zones.
