This paper consists of two parts. The first part establishes the presence of turbulence in low pressure gas reservoirs even at relatively low rates. It is shown that it would be beneficial for these low pressure reservoirs to be tested using multiple rates to establish the level of turbulence. The second part describes a new type of flow test, which is a modified version of the traditional flow after flow test. The method of analysis of this proposed test requires the use of commonly available well testing software, and has been verified using synthetic data.
