Shale gas is playing an increasingly important role in the global energy market. For shale gas wells, optimization of gas production depends on accurate pressure prediction with two-phase flow models. Pressure measurements were carried out in 15 horizontal gas wells at a major shale gas field in China. Classic two-phase flow models were assessed against field measurements. The results show the Mukherjee-Brill method produces relatively low errors in most cases, while the Beggs-Brill method produces relatively high errors in six wells.
