Abstract It is very important to accurately predict the gas well productivity and reasonably allocate production at early development stage of reservoirs. However, both non-Darcy stress sensitivity effects have not been investigated in dual-porosity model tight carbonate This paper proposed a new binomial deliverability single-well proration numerical model, which consider sensitivity. The fiel...

Abstract Although gas-lift is an established technology for improving the performances of oil production wells, simplicity, robustness and accuracy models remain to be fully resolved. As improvement on traditional practice, this paper proposes a new approach modelling performance gas-lifted wells at steady-state conditions. The conceptual framework splits wellbore into two segments. segments ar...

â understanding the flow behaviour in a gas well is crucial for future production strategies, obtaining bottomhole conditions from wellhead production data, analyzing production data and estimating reservoir properties. in this work, the pressure profile and flow regime are studied on four wells of a multi-well, multi-layer gas-condensate reservoir, producing at high rate. the wells are deviate...

Due to the depletion of conventional reservoirs and high demand energy, unconventional will be relied on supply world's energy for foreseeable future. Unfortunately, because their complex storage flow mechanisms, modelling analysis have been very challenging. Although semi-analytical numerical models proposed, these rely somewhat simplifying assumptions require several input parameters. In this...
