Abstract
A well test or well testing is consider as an elaborate plan of activity by an engineer to acquire, analyze and understand data about the properties of hydrocarbons which are trap below the surface of the earth in a reservoir and use the data to understand the reservoir itself. This study investigate the well test analysis of horizontal well in a completely bounded isotropic reservoir in a case where the non-dimensionalize flow parameters are plot on a log-log axis to analyze the pressure response in a horizontal well. It is also clear that horizontal well analysis is more difficult than vertical well analysis, because assessing the flow into a horizontal well requires three dimensions as oppose to a single flow for vertical wells. We develop five (5) well test analysis models to characterize a reservoir and predict the performance of a horizontal well, the non-dimensionalize flow parameters are plot on a log-log axis to analyze the pressure response in a horizontal well, we determine optimum well length for a horizontal well production. We use Source and Green's function with Newmann's product to develop the models, and we implement the results on matlab. We observe that from table 2 to table 11, as LD increases both the PD and PD'decreases when the well is initially open for production, this shows that dimensionless horizontal well length is inversely proportional to both the dimensionless pressure and dimensionless pressure derivative

Keywords : early radial, dimensionless pressure, dimensionless pressure derivative, horizontal well, reservoir.
