• Schlumberger 5 Open Link

  Open Link Reference Manual Overview This guide is designed to
  explain how to use Open Link to interface with PIPESIM from
  external applications. An overview of the functionality of Open
  Link is provided along with the necessary interface functions and
  arguments. This allows you to load both network and single branch
  PIPESIM models, query them (equipment configuration, gas lift
  injection, etc.), and perform simulations. Basic Functions The
  functions described in this document fall into the following
  categories; Get functions — Get the results after a simulation or
  query an item for its current data value,

  such as obtaining the choke bean size. Set functions — Set a
  valve to be used in subsequent simulation, such as setting the
  reservoir

  pressure. Operation functions — Perform an operation on a model,
  such as running a simulation. Potential Usage The Open Link
  functionality could be used in the following cases: Running PIPESIM
  in batch mode with a number of scenarios Creating custom reports
  Importing production data from a database and populating the models
  Running PIPESIM in-conjunction with other Engineering applications.
  Hyprotech have already

  used this functionality to link Hysys and PIPESIM. Utilizing
  Open Link The Open Link functions can be called from any of the
  following: VBA macro. This could be written in Excel, Access, etc.
  Visual Basic programs. C++ programs Supported Interfaces INetModel:
  for network models and network operations ISingleBranchModel: for
  single branch models and operations Dependency MAP Open Link can be
  used to access PIPESIM functionality from external programs. The
  programs that can automate PIPESIM simulations are those that are
  defined as automation clients according to Microsoft standards, and
  in the same way, Open Link is an automation server. Typical
  examples of automation clients include VBA (Visual Basic for
  Applications) macros, which can be written from programs such as
  Excel or Access, C++ and Visual Basic. Open Link provides therefore
  an open architecture where you control and automate PIPESIM
  simulation models through custom programs or macros without having
  to manually enter the data or view the results using the graphical
  interface. It is assumed you are familiar with both PIPESIM and the
  chosen program or programming language in which the automation code
  is to be written. Those new to VBA are recommended to closely
  follow the Quick Start Tutorial and the Case Studies. The Open Link
  functionality is distributed with the PIPESIM installation and is
  included in a number of library files. The main file is
  Net32COM.DLL, which normally resides in the programs directory
  and

  provides the framework and main entry points into both networks
  and single branch simulation models. Net32COM.DLL must be copied to
  the PIPESIM programs directory and registered.

  There are other files that support Net32COM, for instance
  FluidModelCOM.DLL and FlowCorrelationCOM, which provide access to
  properties defined in the fluid models and flow correlations
  respectively.

  Each library file, in turn, defines at least one interface,
  which is a logical entry point into a well-defined area of
  functionality. Each interface includes a number of public access
  functions that set or get a specified property or just perform
  operations (that is run a simulation). As an example the
  FluidModelCOM library defines two interfaces: IBlackOil, for black
  oil models and ICompositional, to deal with compositional models.
  IBlackOil defines property functions

  PIPESIM

• Schlumberger 6 Open Link

  such as API, Watercut or GasSG. These properties can be set
  (assigned) to a model prior to a simulation run or they can be get
  (retrieved) and copied into an Excel cell.

  The Modules and Interfaces section lists the modules and
  interfaces that are part of Open Link. This document contains
  further details of the modules and interfaces, together with some
  code samples. Highlighted items represent information that is new,
  previously unpublished or amended from the previous PIPESIM
  release. The present reference guide applies to the release version
  2008.

  Quick Start Tutorial This quick start guide shows macro code
  written in VBA using Microsoft Excel. Even though each language
  implements its own particular syntax, the basic logic to write an
  Open Link code or macro will be identical. A number of case studies
  along with VBA code using Excel are provided under the ..Case
  StudiesOpen Link directory. 1. Before you start — you must let VBA
  know about the Open Link interfaces. To do this, click

  on Tools | References from the main menu in the VBA window. You
  should now see a dialog box like the one below.

  2. Scroll down the list of available references until you find
  the Net32COM 1.0 Type Library.

  Check the box to the left of the reference. 3. Now do the same
  for the FluidModelCOM 1.0 Type Library and for PNSReader 1.0 type
  library. 4. Click on OK to close the References window. Loading and
  running an existing model 1. Load the existing network model: Small
  Network.bpn, which is shipped with the PIPESIM

  installation and normally located in: C:Program
  FilesSchlumbergerPIPESIMCase StudiesNetwork AnalysisSmall
  Network

  If the model were opened from the PIPESIM graphical interface it
  would look like the picture below:

  PIPESIM

• Schlumberger 8 Open Link

  2. Using the VisualBasic editor (you can quickly open it from
  Excel using the shortcut Alt+F11)

  create a variable of the type INetModel to perform the basic
  interaction with the network model. We will call it NetModel: Dim
  NetModel As New NET32COMLib.INetModel

  3. Open the model: NetModel.OpenModel C:Program
  FilesSchlumbergerPIPESIMCase StudiesNetwork AnalysisSmall
  NetworkSmall Network.bpn

  4. Run the model (asynchronously): NetModel.RunNetwork2 False,
  «-B»

  The first argument, in this case False tells the calculation
  engine not to use a restart file and the second argument -B is an
  engine switch that instructs the engine to run in batch mode. For
  more information on engine commands please refer to the PIPESIM
  help. When executing this macro you should see the calculation
  engine running in the background. This process is run
  asynchronously which means that the macro will continue its
  execution without waiting for the simulation run to finish. If you
  want your macro to stop until the engine terminates in order to,
  say, display a result,

  then you can replace the line above by the following code:
  NetModel.RunNetwork2 False, «-B» bRunning =
  NetModel.GetIsModelRunning While bRunning = True bRunning =
  NetModel.GetIsModelRunning newHour = Hour(Now()) newMinute =
  Minute(Now()) newSecond = Second(Now()) + 1 waitTime =
  TimeSerial(newHour, newMinute, newSecond) Application.Wait waitTime
  Wend MsgBox «Finished…»

  This code will run the simulation synchronously. It starts the
  simulation and then waits until it is finished. It checks every one
  second for the engine status through a call to GetIsModelRunning.
  When GetIsModelRunning it returns False indicating that the
  simulation run is finished, the macro code displays a message
  box.

  PIPESIM

• Schlumberger 9 Open Link

  Getting results We would like to display some results from the
  simulation. The library that reads the results file is PNSReader
  and we must create a variable of the type PNSCom in order to
  extract data from the simulation output. The public access
  functions available in PNSReader are detailed in PNSReaderCOM. 1.
  Create a PNSCom variable, lets call it results:

  Dim results As New PNSREADERLib.PNSCom 2. Read the results file.
  This file is located in the same directory as the model file and
  has the

  same file name but with the extension .pns:
  results.ReadPnsFile(C:Program FilesSchlumbergerPIPESIMCase
  StudiesNetwork AnalysisSmall NetworkSmall Network.pns)

  3. Get the pressure and temperature at the sink Sink_1 (see
  model picture above) Dim index as Long Dim pressure as Double Dim
  temperature as Double index = results.GetNodeIndex(Sink_1) pressure
  = results.GetNodeVariableValue (index, «Pressure») temperature =
  results.GetNodeVariableValue (index, «Temperature «)

  In the same way variables such as LiquidRate, GasRate, MassRate,
  GLR or WaterCut can be obtained for Sink_1 or any other node in the
  network.

  Changing BlackOil fluid parameters So far, we have opened, run
  and obtained results for a network model as it was originally
  defined within the PIPESIM graphical interface. In this step, we
  will change some parameters to the opened model. Here is where the
  true power of Open Link starts to show, the Excel spreadsheet may
  define a range of values to be tested in the context of a what if
  scenario and multiple simulation jobs may be set up to compare
  results for a range of input values for one or more properties. 1.
  Create a BlackOil variable:

  Dim BlackOil As New FLUIDMODELCOMLib.IblackOil 2. Get the
  BlackOil model from the network

  Set BlackOil = NetModel.BlackOilDefault The BlackOil variable
  has been filled with the values defined in the blackoil model in
  NetModel. You can corroborate this by adding a watch with the VBA
  debugging tool and inspecting the different variable fields. 3. Set
  a Watercut value of 15%:

  BlackOil.Watercut = 15 4. Set an API value of 27.5:

  BlackOil.API = 27.5 5. Set this BlackOil with a modified
  watercut and API back into the network:

  NetModel.BlackOilDefault = BlackOil 6. You can now re-run the
  model with this new values, get the new results, display them in
  an

  Excel cell or plot, etc.

  Changing a choke property 1. The following piece of code sets a
  new value for the choke bean size in Choke which is

  defined in the single branch model that corresponds to the
  production well Well_1. NetModel. SetPropertyVal (Choke, Well_1,
  «Bean Size», 3.5, «inches»)

  The above line sets bean size = 3.5 inches to Choke in Well_1.
  .

  Saving the changes 1. Any changes made to a single branch or
  network model can be saved simply by calling the

  SaveModel() function. Dim bOK as Boolean bOK =
  NetModel.SaveModel(C:MyOpenLinkModelsNetwork.bpn)

  PIPESIM

• Schlumberger 10 Open Link

  The argument is the full path to the file where the model will
  be saved. It can also be re-saved to the original model file. 2.
  bOK will be TRUE (1) or FALSE (0) depending on whether the save
  operation succeeded or

  not. As with all Open Link function calls that return a
  TRUE/FALSE state, a FALSE value indicates that some kind of error
  condition occurred and an error description can be obtained by
  calling GetLastError(): Dim Error as String If bOK = False Then
  NetModel.GetLastError Error MsgBox errorStr End If

  Case Study 1 Building a Well Model from Excel Problem Outline It
  is often desired to build PIPESIM well models from a corporate
  database. The problem can be solved by: 1. Pasting the wells data
  in excel. 2. Using a VBA routine containing Open Link statements to
  automate the Bps files creation. This case study illustrates the
  resolution of such a problem.

  Requirements It is assumed that the reader is familiar with the
  basics of building models in PIPESIM. No prior knowledge of VBA
  (Visual Basic For Application) is required. VBA is a programming
  language that is accessed from Microsoft Excel. VBA statements can
  be used to interact with Microsoft Applications. These statements
  cannot interact with PIPESIM. Open Link is the name given to a
  group of statements that can be used in VBA to interact with
  PIPESIM.

  Procedure 1. Create a Well Model Template. (That is build a well
  model in PIPESIM but do not fill any of

  the objects that make up the model with values). Save the well
  model template with the name template.bps.

  2. Organize the wells data in tabular form in Excel. 3. Write
  the VBA routine that will create a Bps file for each well of the
  spreadsheet. (The routine

  will make use of the model template.bps as will be shown further
  down in the text). 4. Run the routine The Bps are created and
  stored in a directory specified in the routine. Step by step
  tutorial Create a Well Model Template 1. Open PIPESIM Open a new
  well performance analysis window as shown below.

  2. Create the following Well Model in the opened window. 3. Save
  the model with the simple model description selected in both the
  tubing object and the

  flow line object. This is done by double-clicking on both the
  flowline_1 and tubing_1 object, selecting simple model in each user
  form and pressing on the button OK.

  PIPESIM

• Schlumberger 12 Open Link

  4. Save the well model under the name template.bps with the
  following path:

  D:/OpenLink/template/template.bps Create a table of wells data
  in Excel (2 vertical gas wells) 1. Open Excel. 2. In the Opened
  workbook, select sheet 1 (the sheet should be selected by default).
  3. Create the following table in Excel (4 Rows 24 Columns).

  4. Start the table at the cell $A$4 and finish at the cell $X$7.
  5. List of the 24 columns (A to X in order) (The values are given
  for each column):

  A: General Data:

  Pressure at the end of the flow line. psia (150,440)

  6. In cell $A$8 write the template path:
  D:/OpenLink/template/template.bps 7. In cell $A$9 write the path in
  which the Bps files are to be stored:

  D:/OpenLink/ 8. In cell $D$11 write the surface temperature: 90
  F. 9. Save the current workbook under the name Openlink.xls with
  the following path:

  D:/OpenLink/Excel/Openlink.xls Preliminary steps 1. Enable
  Macros in your workbook. 2. Select the Menu tools Sub Menu Macro
  Security as shown below.

  PIPESIM

• Schlumberger 14 Open Link

  The following user form should appear:

  3. Select Medium. High does not let the user run any unsigned
  Macros. 4. Insert a Button in the workbook that will launch the
  routine. First, display the Control

  Toolbox Toolbars.

  PIPESIM

• Schlumberger 15 Open Link

  5. Then insert a button in the spreadsheet by clicking on the
  Command Button Icon in the Control Toolbox; and clicking and
  dragging the button in the spreadsheet. This is shown below:

  Design Mode Icon.

  Command Button Icon.

  The default name of the button is CommandButton1. Note: Clicking
  on the Command Button icon activates the design mode that allows
  you to place buttons and other types of controls in the
  spreadsheet. You will need to deactivate the design mode manually
  when you want the routine associated with the button to be executed
  when you click on it.

  PIPESIM

• Schlumberger 16 Open Link

  6. Next change the name of the button by right-clicking on the
  button CommandButton1 the following menu should appear:

  7. Click on CommandButton Object Submenu Edit. You can now
  change the caption of the

  button CommandButton1 to: Create Well Model. 8. Open the VBA
  Editor Windows. As the design mode is activated, it is possible to
  open the VBA

  editor windows by double-clicking on the button CommandButton1.
  The following window should then appear: Private Sub
  CommandButton1_Click() End Sub

  The window that contains the statements is called the Code
  window. You write VBA routines in the Code window. The word Sub in
  the first line indicates to the computer that it is the beginning
  of a new routine. (In effect, several routines can be written in
  the same Code window). The word CommandButton1_Click in the first
  line indicates to the computer that the routine following can only
  be executed by clicking on the button CommandButton_1. The
  statement End Sub indicates to the computer that this is the end of
  the routine. Any routine must finish with this statement.
  Activating the Open Link statements Libraries. In order to be able
  to write our routine using Open Link statements we need to indicate
  to the computer that we are going to use those statements. We need
  to activate those statements so that they can be understood by VBA.
  1. We can activate the Open Link statements by clicking on the menu
  Tools, submenu

  References.

  PIPESIM

• Schlumberger 17 Open Link

  You should now see a dialog box like the one below:

  2. Scroll down the list of available references until you find
  the FluidModelCOM 1.0 Type Library.

  Check the box to the left of the reference. 3. Now do the same
  for Net32COM 1.0 Type Library and NODALOPLib.INodalAnal. 4. Click
  on OK to close the reference window. Each of the three library
  activated is a group of Open Link statements that can be used in
  VBA to communicate with PIPESIM. These libraries will be available
  from Excel after having installed PIPESIM. They need to be
  activated before they can be used while programming. Note: If a
  routine is passed from one computer to another, and it does not
  work on the receiving computer, it is because the Open Link
  Libraries have not been activated. Write the VBA routine using Open
  Link Statements: 1. Write the following routine: The actual
  workings of the routine will be explained in Case Studies.

  Case Study 2 — Nodal Analysis Problem Outline It is required to
  see if our production data is consistent with what the model
  predicts the flow rate should be. We will run a nodal analysis on
  each of the wells. The boundary conditions of the problem are the
  reservoir static pressure and the outlet pressure of the model
  (i.e. the downstream end of the flow line). The Stock tank gas flow
  rate at the operation point will be compared to the Gas flow rate
  given in the production data.

  Requirements It is assumed that the reader is familiar with the
  PIPESIM Nodal Analysis User Form.

  Procedure You will write a VBA-Open Link routine that uses the
  table built in the previous case study. The routine fills in a
  Nodal Analysis operation interface using the static pressure,
  tubing ID and Outlet Pressure stored in Excel and then assigns this
  Nodal Analysis operation interface to the Well Models created in
  Case study 1. Each of the models is then run. A Nodal Analysis plot
  (system plot_.plt) is produced for each well. You can then check on
  the graphs if the stock tank flow rates at the operation points are
  consistent with the production data.

  Step by Step Tutorial 1. Open the Excel File (OpenLink.xls)

  D:/OpenLink/Excel/Openlink.xls 2. Insert a second button in the
  Spreadsheet. This is done using the control toolbox as in Case

  Study 1. The default name of the button will be
  CommandButton2.

  3. Open the VBA editor. This is done as in Case Study 1 by
  double clicking on the button

  CommandButton2. The code written for the previous case study
  will be visible. Private Sub CommandButton2_Click() End Sub
