Abstract: Petrographic data of a carbonate reservoir in a subterranean region is received. Mud content of the carbonate reservoir is determined based on the petrographic data. A depositional porosity of the carbonate reservoir is computed based on the mud content. An amount of cementation of the carbonate reservoir is determined. A porosity loss by compaction of the carbonate reservoir is determined based on the mud content and the amount of cementation of the carbonate reservoir. A post-compaction porosity of the carbonate reservoir is computed based on the depositional porosity, the mud content, the amount of cementation, and the porosity loss by compaction.

Abstract: A hands-free system for capturing data and generating reports recognizes speech as text and commands to create a set of entries intended to have a mathematical relationship to each other such that, if these entries fail to satisfy the relationship, a voice synthesizer generates a warning signal to indicate an error by the user.
