Estimation of non-pay natural gas reserves

Increasing natural gas production from tight terrigenous reservoirs

“…/t for model with permeability of 9.7 mD to 0.22 m 3 /t for model with permeability of 93 mD) [12]. It is also worth noting that with increasing permeability the absolute dependence of the specific volume of adsorbed gas on temperature decreases.…”

“…At the first stage the horizontal well length was estimated, at the second stage -the impact of the fracture length in horizontal wells on technical and economic parameters was determined, and the third stage included the determination of the optimal fractures density. More details about the research was presented in [12].…”

“…The economic analysis was based on the determination of net present (discounted) value (NPV) and was conducted on the basis of national legal regulation acts and international publications [12]. NPV was determined by the equation:…”
