Thickness of gas bearing formation acts definitely on producibility of lower permeability sandstones with same petrophysical properties and same gas saturation.
对于低渗透岩性气层，在物性和含气饱和度相同背景下，气层厚度的大小对产能的高低起决定性作用。

The interpretation of fracture and vuggy saturation, the determination of effective thickness and the distribution of reservoir are the main problems in reserve calculation.
The corroboration of effective reservoir lower limit in reserves calculation respects parameters influence effective reservoir thickness, porosity and gas saturation directly.
