2 Installation and WindowsBasics

This chapter explains how to install PVTP on your computer. The guide assumesyou have a working knowledge of Windows terms and procedures. If you areunfamiliar with the Windows operating system, we recommend you read therelevant sections in the Microsoft Windows User's Guide to learn more aboutWindows operations.

This chapter gives instructions on installing the program to a Windows 98, 2000 orWindows NT operating system.

2.1 Software and Hardware Requirements

The program supports all Windows-certified device drivers that are shipped withWindows. The list of devices, software and hardware supported by Windows isincluded with the documentation of your copy of Windows.

PVTP can be run as single User licence or on a Network. In either case, a special

security key is needed. The security key is called Bitlock for stand-alone licencesand Hardlock for network licences

The security key is provided by Petroleum Experts.

The minimum requirement recommended for PVTP is Pentium 450 MHz machinewith 128 Mbytes.

In order to install the software from the CD, the machine should have access to aCD drive.

For a stand-alone licence, a security key (Bitlock) provided by Petroleum Expertsmust be attached to the parallel printer port of the PC before PVTP can be run.

For network installation, the security key (Hardlock) can be attached to any PCcommunicating with the network.You should refer to the separate installation procedure for network Hardlock sentwith the purchase of a Hardlock licence.

If PVTP has been installed for the first time on a machine, the Bitlock driver must beinstalled on this machine in order to establish the link between the software and thesecurity key (Bitlock driver).

In order to install the Bitlock driver, you will have to start from the main Windowsscreen. Here you click on |Start |Programs |Petroleum Experts IPM |Utilities and

then start the “Set-up Bitlock Driver”.

Chapter 2 - Installation and Windows Basics 3 - 8

2.1.1 Upgrading from a Previous Version

For convenience in running linked models, Petroleum Experts software productsnow installs by default into a common sub-directory \Program Files \PetroleumExperts\IPM X.Y.

If you wish to keep an original version of the program, back it up into anotherdirectory before installing the upgrade.

All program upgrades are backward compatible. This ensures that data filescreated with earlier versions of the program can still be read by laterprogram versions. However, if you save a data file with the new version,that file can no longer be opened by earlier versions! As with all newsoftware installations, always back up your PVTP files.

2.2 Installing PVTP Before installing the program on your computer, you should first determine:

The drive where the program is to be installed•

•

•

•

•

•

•

•

The amount of space available on the selected drive

When installing on a network, verify you have the necessary access rights tocreate directories and files on the designated volume.

What Set-up doesThe installation procedure:

Creates a program directory on your hard disk.

Creates a sample files sub directory on your hard disk.

Unpacks the PVTP program and related files to the selected drive anddirectory.

Creates a program initialisation file PROSPER.INI in your Windows directory.

Creates a new Windows program group and icon for both PVTP andREMOTE.

If you are updating PVTP, the set-up can be used to modify, repair or remove

components of the IPM suite. In this case, follow the online instructions

To avoid potential system resources conflicts, please shut down otherapplications before running SETUP. Some anti-Virus programs caninterfere with the installation process and may need to be shut down.

2.2.1 Running Setup

To install the PVTP program:

1. Insert the program installation CD in the correct drive.

2. From the main screen of Windows, click on |Start |Run and follow theonline instructions.

The option “Repair” is recommended.

2.2.2 The PROSPER.INI file

The PROSPER initialisation file contains the settings you use to customise the PVTP application environment. Settings such as the program data directory, customisedunits system, last file accessed and the colour settings of your screen graphics areall stored in this file. You do not need to manually modify the PROSPER.INI file.

The program will automatically record any changes to the settings.

PVTP automatically creates the PROSPER.INI file in the Windows default directoryusing the program's default settings. The location of this file is defined by this entryin your WIN.INI file:

[PETROLEUM EXPERTS] IniPath=PROSPER.INI

We do not recommend changing the location of the PROSPER.INI file. If however,

you want to do so for specific reasons (to place it on a specific network drive), takethe following steps:

1. First copy the existing PROSPER.INI file to the required directory. Forexample:

COPY C:\WINDOWS\PROSPER.INI

U:\NETWORK\APPS\PVTP\PROSPER.INI

2. Next amend the 'IniPath' entry in WIN.INI to correspond to the newdirectory and path where the PROSPER.INI is now located. e.g.:

IniPath=U:\NETWORK\APPS\PVTP\PROSPER.INI

During the installation PVTP unpacks a number of files onto your computer in the

specified installation directory. The unpacked files should not be modified, removedor moved to another directory.

2.3 Starting PVTP

Before starting the program, make sure the software protection Bitlock (dongle) isconnected to your PC and that the Bitlock Driver has been installed .

2.3.1 Connecting The Software Protection BitlockThe software protection Bitlock must be attached to the PARALLEL printer port. Do Not connect the Bitlock to a serial port, as this can damage the Bitlock or your PC. If you areusing protection Bitlocks for other software, we do not recommend stacking the Bitlocks.We suggest using only the correct Bitlock with the appropriate software. Stacking Bitlocksmay lead to incompatibilities between Bitlocks, and may cause read/write or access errorswith some Bitlocks.

2.3.2 Creating the PVTP Icon

The PVTP icon should appear automatically in the correct folder under thePrograms menu after installation.If this does not happen, invoke the Start menu and select Settings | Taskbar.Select the Start Menu Programs tab and click on Add to add the PVTP program to

the menu. Follow the instructions on the screen.To start the program subsequently, select the PVTP program from the programs

menu of the Start menu.

It is also possible to create a shortcut to PVTP on the main Windows desktop. Todo this, click the right hand mouse button anywhere within the desktop and selectNew | Shortcut from the resulting popup menu. Follow the instructions on thescreen to create the shortcut to PVTP.EXE.PVTP can then be executed by double-clicking on the shortcut icon.

2.4 REMOTE Software Utility

All Petroleum Experts' software requires a software protection device to allow it run.The utility program REMOTE.EXE provided with our software allows you to access

the software protection device to view information such as the enabled programoptions, program expiry date(s), and Bitlock number.

You may have been sent an inactive software device. For security, authorisationcodes are always sent separately to the Bitlock. On receiving the softwarepackage, we ask that you contact us to confirm reception. We will then verify theuser access code programmed on your Bitlock, and issue a set of codes to activatethe Bitlock. In these situations, the necessary codes will be sent to you byfacsimile, letter or email.

To enter the codes, you will need to run the REMOTE application installed with

PVTP (see next section for more details).You can also create a shortcut to the Remote application from the Windowsdesktop.For this, click on |New |Short cut anywhere on the Windows screen and follow theonline instruction. The program file is called REMOTE.EXE.

2.4.1 Entering the User Authorisation CodeYou enter user authorisation codes only if:

The software protection Bitlock you have received is inactive,•

•

•

Access period for the program has expired, or

You have acquired new program options

To enter authorisation codes take the following steps:

Double click the REMOTE icon (or select the REMOTE program from thePrograms menu of Windows 98). A screen similar to the following will appear:

2.4.2 Updating the Software Protection Bitlock

Access to the software ceases automatically when the license expiry date elapses.You are, however, reminded several days in advance. This gives you sufficient

time to contact Petroleum Experts about new codes. Software Bitlocks requireupdating when:

•

•

The software license period has ended.

The annual maintenance fee is due.

Software protection Bitlocks also needs updating when you acquire otherPetroleum Experts software packages. The procedure to update the Bitlock is thesame as for entering the authorisation codes. When the appropriate screenappears, enter the codes provided - from left to right beginning with the top row.Press OK to activate the codes, or Cancel to quit the update. To view the expiry

date for any of the listed programs, simply click (highlight) the software name.

Perpetual licence holders will be sent on yearly basis an utility programwritten by Petroleum Experts, that automatically updates the Bitlock. Theupdate is hard-coded inside the utility program. step-by-step instructions aresent with this utility program.

2.5 Program Check List

To ensure trouble free processing and access to the PVTP program, please check:

•

•

•

•

•

•

You have sufficient disk space.

The software protection Bitlock is connected to your Parallel printer port. DoNot connect the Bitlock to the serial port, as this can damage the Bitlock oryour PC.

The software protection Bitlock is firmly in place ensuring a good connection.If the Bitlock is loose the program may not be able to access the dongle to

activate the program.

The printer cable is firmly attached to the software Bitlock. Your printer shouldbe turned ON and be put on-line.

The PC system date is set correctly to the current date (i.e. today's date).

3 File Management

This section describes the menus, options and procedures used in PVT to create new files

and open or save existing files. The Units system and how to define printer settings and isoutlined. The menus described in this section are the PVT File menu and Units menu.

The File menu provides the ability to open , close , save etc. The PVT package allowsmultiple files to be opened at once. The Window Menu allows the user to swap betweenopened files.

This menu offers the user the standard options available from an MDI (Multi DocumentInterface)

The PVT package can load multiple PVT Project Files each of which occupies its ownwindow.The windows can be selected ,cascaded,arranged and tiled via this menu.

Before you can work with a file, it must be opened. This can be done using the File menu

Open option or the icon.

To protect your work, you should save your data on a regular basis. Saving a file is doneusing the File menu Save or Save As options. This simple procedure could potentiallyprevent hours of work and analysis being lost.

To start a new PVT Project file use the File menu New option.

3.1 PVT File Types PVT uses a flexible file structure that enables data to be easily exchanged between files

and other application programs. In PVT, information is grouped into the followingcategories:

Separator DataIn common with the CCE calculation (Section 8.4) , the Table Export displays contains asection for Separator Data. This allows the user to define a 5-stage separator train through

which the CCE liquid will be flashed to correct the Oil FVF and GOR. The processes whichare used to return an oil to standard conditions can significantly change the final oilcharacteristics and the amount of gas liberated on the way.

All stages do not need to be entered and a last flash to standard conditions is alwaysincluded.

The Used checkbox within the separator data area switches the correction on and off. TheSetup button allows the stage characteristics to be changed by calling the dialog shown infigure 3.2b.

3.2.9 MBAL MultiI-PVT Export (*.PGD)

PTG files are files which contain the data in a form which can be imported into thePVT/Fluid Properties/Import section of Petroleum Experts MBAL program. The MBAL program

should have the tank model Variable PVT selected.

The format is fairly general and could be used for other packages. An ASCII text file is produced by this procedure. The process is carried out using theExport option within View properties display or using the Export Option from the File Menu.

The first stage in the export process is to calculate the Compositional gradient via avariation of the Compositional Gradient Calculation Input Dialog (see figure 3.2e).

The only difference is a change of label on the button from Calc to Export. Input the depths or range of depths required and press on Export.. This brings up theExport dialog.
