Predicting the performance of wells in stress-dependent gas reservoirs can be quite challenging to most conventional reservoir<br>engineering tools. In this paper, a fully coupled geomechanics and fluid flow analytical model was developed for modeling well<br>performance in stress-dependent gas reservoirs. For tight and unconsolidated gas reservoirs that exhibits variable formation<br>compressibility, reservoir compaction, and stress-dependent properties deterioration such as permeability and porosity, the<br>geomechanics effect may not be ignored. All these physical contributes play an important role on well performance. The coupled<br>model considered all these contributes and evaluate their impact on well productivity .The model also accounts for the effect of the<br>transient flow period and variable producing conditions in addition to the effect of non darcy flow in gas wells.
