This work investigates the analysis of well test pressure data from a restricted-entry well using pressure and pressure derivative type curves constructed from constant-rate solutions. For cases where wellbore storage effects are negligible, it is shown that type curves constructed from constant rate solutions can be used to analyze rate data from wells producing at a constant bottom-hole pressure and that these type curves can also be used to analyze data obtained from gas wells. For cases where data are influenced by wellbore storage and skin effects, it is shown that a new analysis procedure using complete-penetration type curves based on dimensionless pressure and a dimensionless pressure/pressure derivative group can usually be used to obtain a complete analysis of data. The analysis procedures presented yield estimates of horizontal permeability, the mechanical skin factor and the vertical permeability.
