V. 4.00.03 • 09-05 Saphir Guided Session # 1 A01 • Initialization This chapter is an introduction to the basic features of Saphir. It is assumed that you have installed Ecrin workstation or Saphir stand alone to follow this session. The session can be followed in all levels of Saphir except the Saphir reader. The session will use the following files installed in the example directory during the main installation of Saphir or workstation Ecrin: SapGS01.rat, the rate file and SapGS01.pre, the pressure file. The extension to the files is not important here as any ASCII file can be loaded by the application. If the workstation has been installed click on the icon in the application toolbar and then new , if Saphir has been installed as a standalone application click on new project directly. This opens in succession two dialogs: A01.1 Initialization dialog 1 of 2 This dialog allows you to choose the test type, reference fluid type, the available fluid rates, net drained thickness, well radius and average porosity. Set the reference time to Dec 4, 1999 at 00:06:45 hours. Keep all other parameters as the suggested default. Click .

Saphir Guided Session # 1• SapGS01-3 Saphir 4.00 © KAPPA Engineering 2005 Doc. V. 4.00.03 • 09-05 B01 • Loading data B01.1 • Loading rates Click on the icon. This will initialize the load sequence which is normally a sequence of two dialogs. Specify an ASCII file in the “Define data source” dialog and click on to browse to the file SapGS01.rat in the Example directory. A preview of the file will be shown in the dialog as illustrated in Fig B01.1. Fig B01.1 Load step 1 – Define data source Click to go to the Data Format dialog. Saphir has recognized the file as valid and has automatically assigned the first column as “Decimal Time” and the second as “Oil Rate”. This is known as “free format”. The units are the correct units so there is no need to change the formatting proposed by Saphir. However the file contains steps and values, thus you will choose the radio button “Steps: durations”. See Fig B01.2. Fig B01.2 Load step 2 – Data Format
