Installation and learning guide Saphir Guided Session # 2• SapGS02-1 Saphir 4.00 © KAPPA Engineering 2005 Doc. V. 4.00.03 • 09-05 Saphir Guided Session # 2 A01 • Requirements It is assumed that you have already studied the guided session #1 in order to know how to load and organize the data. In this session we will bypass the initialization phase and load directly an already created Saphir file SapGS02.ks3 that you will find in the installation Examples directory. The session will cover the building of a manual model and pick options, KIWI and multiple models. B01 • Pseudo steady state double porosity Launch the application. Saphir has already been installed either as stand alone or as part of the Ecrin suite workstation. In case that you are running the workstation, click on the icon and then on icon to open the file, in case Saphir is running as stand alone click directly on the icon. Browse to the Examples directory and open SapGS02.ks3. Your screen should look like Fig B01.1. Fig B01.1 Saphir main screen

Installation and learning guide Saphir Guided Session # 2• SapGS02-2 Saphir 4.00 © KAPPA Engineering 2005 Doc. V. 4.00.03 • 09-05 The pressure derivative shows the typical trends of a reservoir with pseudo steady state double-porosity. However, none of the theoretical stabilization levels is apparent in the data. In a double-porosity (or 2 layer) model, IARF (Infinite Acting Radial Flow) must correspond to radial flow in the total system. The final diagnostic (the decision as to which interpretation model may be the most appropriate) can only be made after the interpreter has fixed the level of the IARF flow line (the dotted white horizontal line). In this case as the shape of the derivative curve indicated the response from a double porosity reservoir it is obvious that the white dotted line has to be moved above the tell tale valley in the derivative. This can be achieved by simply click and drag in the loglog plot moving the white dotted line to correspond to the very end of the derivative curve. You can also use the semilog straight-line option and regress a line in the loglog plot through the end of the derivative data. Maximize the log-log plot using a double click in the plot header. Define a semilog line at the end of the
