Boberg-Lantz method is one method used to predict the performance of the production rate of steam injection wells huff & puff. The method describes the process of stimulation by using an analytical model cylindrical shape. Huff and puff steam injection requires 100% quality steam in order to obtain a satisfactory oil. Therefore, this study sought further influence over the production performance of oil produced when taking into account the decrease in vapor quality due to loss of temperature along the well that has been developed into a programming language Fortran. The study is to develop a model for forecasting performance of steam injection analytically written in the Fortran programming language to use in comparing the results of the oil production rate calculation does not take into account the decline in the quality of the steam and the steam quality degradation into account. Various parameters affecting the value of the quality of the steam injection process steam huff and puff is depth, the injection flow rate, productivity index, while the injection temperature, latent heat, the radius wells, cement thermal conductivity, thermal conductivity of the earth, the heat conductivity of insulation, and radius of insulation. The study shows the vapor quality has not changed enough away, so that the acquisition of the oil flow rate did not change significantly. But if the steam quality obtained at a certain depth has quite a big difference then the acquisition of the flow rate of oil production will change as well. It is causing a significant change of steam quality one is cement in the well is damaged or is currently less well cementing process or some of parameters that have extreme value in the well.
