1. The document provides calculations to determine well performance parameters like maximum production rate (Qmax), productivity index (PI), and pressure profiles from reservoir and well data. 2. An example calculation is shown to determine Qmax of 11,930 BFPD for well KB#059 using the Vogel equation and data provided. 3. The productivity index equation is derived from the original equation, showing that PI units are BPD/psi. 4. Another example calculates the Qmax of well KB#059 to be 17,834 BFPD using a different set of input data.
