5 Opening a Project Click on the icon PseisDB located on your desktop. Petrosys also runs on Linux and Solaris as well as PC. A project selection dialogue box will be displayed. Double click on the project called Australia_TARGA. If you cannot see this project in the dialogue box it can be added to the list by selecting Project/Add and browsing to the directory in which the project is located. Starting Interactive Mapping After starting the project, the main start-up panel of Petrosys is displayed. Click on the button labelled Interactive to open a mapping window. Getting Started With Petrosys 5

6 Selecting a Mapsheet To begin with we will create a map using data from a variety of sources. When the mapping window opens choose MapSheet/Select Ensure that the TARGA REGIONAL mapsheet is selected. Click OK. A mapsheet is a template showing an Area of Interest at a defined scale and with a particular style applied. The mapsheet is fully customisable in terms of scale, coordinate reference system and annotation. A customisable titleblock containing specific company information is also available to place on the mapsheet. Choose Display/2D seismic/smt In this exercise we will be using a direct connection to an SMT database. Petrosys can seamlessly read data directly from a variety of data stores including OpenWorks, Finder, SeisWorks, Geoframe and more. Where direct connection is unavailable, Petrosys can import data from each of these data sources, and more, to be manipulated in Petrosys. 6 Getting Started With Petrosys

7 Displaying Seismic A dialogue box is displayed that allows the user to define the appearance of the seismic lines on the mapsheet. A link must be established with the SMT database so that the lines can be read. Click on the button beside SMT Database. When the Select Database Connection dialogue box appears click Add... In the Add Database Connection dialogue box double click the first line (-> Select*.tks file ). The Enter Password dialogue box now appears. Browse to locate the psys_2d_smt_project.tks file (\seis\smt_data\australia_targa\psys_2 d_smt_prject.tks). Right mouse click on the button beside Projected CRS to associate the database with the default CRS (Coordinate Reference System). Click OK in the Enter Password dialogue box then click OK in the Select Database Connection dialogue box then click OK in the Display Seismic Lines dialogue box. Your map should appear similar to that shown below: Getting Started With Petrosys 7

8 Displaying Wells You should now have the 2D seismic navigation lines displayed on your mapsheet. To display well paths and well information in the area choose Display/Wells/SMT and select data source SMT. A dialogue box similar to that for the 2D seismic lines appears. This dialogue box allows the user to fully control the appearance of the wells on the map. Data that is associated with the wells (e.g. formation top depths, attribute values or isopach thicknesses) can also be selected for display here. Set up the dialogue box so that the settings match those shown here. Click OK. The wells should now be displayed on the map. Petrosys shows when you have an option selected in a dialogue box by placing an asterisk next to the name of the tab. In this case Well symbols, Well annotation and Paths are selected to be displayed on the map. 8 Getting Started With Petrosys

9 Your map should appear as above with seismic lines and wells displayed. Getting Started With Petrosys 9

10 Displaying Grids Select Display/Grid/Colorfill... A dialogue box is displayed allowing the user to control the appearance of the colorfill grid. Ensure v_twt.gri is the Grid file selected. If not, click on the button beside Grid file, select it and click OK. Accept the defaults on all other parameters. Click OK. Petrosys allows you to fully control the appearance of your surface. Any surface you display can be clipped at a minimum or maximum value of your choice. Petrosys can display surfaces with a variety of built- in colorfill gradients or you can create your own. The translucency of any displayed surface can be adjusted enabling the generation of sophisticated multi-layer maps. 10 Getting Started With Petrosys

11 The colorfill grid is now displayed on the mapsheet with a colorfill gradient that reflects the topography of the surface. Adjusting Display Order The grid above obscures the data previously displayed on the map. Click the Modify parameters for displayed items button on the left hand side toolbar of the window (circled above). This panel can also be accessed from the Display/Modify... menu. To place the colorfill grid surface behind the other data on the map, highlight the Surfaces object type in the dialogue box and click the downward pointing double arrow button. Your map display should now have the grid surface placed behind the wells and seismic data. Click Close. The Display Modify dialogue box allows the user to alter the appearance of all items currently displayed on the mapsheet. The user can access the drawing parameters for each object by double clicking the appropriate object in the list. The user is also able to remove objects from the map using this dialogue box.

12 Displaying Contours Choose Display/Contours In the Display Contours dialogue box ensure v_twt.con is selected. If not, click on the button beside Contour file, select it and click OK. Type 10 under Increment in the CONTOUR LINES section. Click OK. 12 Getting Started With Petrosys

13 Your map should be displayed as above. Adjust the display order by choosing Display/Modify and placing the contour lines behind the seismic and well data but above the grid surface as shown below. Getting Started With Petrosys 13

14 Displaying Spatial Data Select Display/Spatial When the Display spatial dialogue box appears select Shape File from the Spatial data source drop down menu. Click the file browsing button (circled) and select the file permits.shp. Click the Shape tab and press the button beside Line Style. Change the line Width to 3. Click OK in all boxes to display the permit boundaries on the map. 14 Getting Started With Petrosys

15 Your map should now appear as above. Zoom Control It is possible to zoom in to the map using the zoom tools on the toolbar to the left of the main map view screen (outlined in red). Getting Started With Petrosys 15

16 Querying Map Data Petrosys allows the user to query data that is displayed on a mapsheet but is held in an external database. Hold the cursor over a seismic line and press the left mouse button. The cursor should change to a target that can be dragged along the seismic line. Note that the line name, shotpoint and coordinates are displayed in the information bar at the bottom of the Petrosys window. Repeat this action with a well path and note the information displayed in the information bar. Highlight a well with the left mouse button. Now click the right mouse button on this well. A menu is displayed with several options. Note that well header, formation tops and directional survey data can be read directly from the database. Select some of these options and examine the data. Saving Map Display Lists and Mapsheets It is important to understand the distinction between display lists and mapsheets in Petrosys. Petrosys saves all the objects that are displayed on a mapsheet in a display list that can be retrieved and viewed again at a later date. This file is stored independently of the mapsheets that may be present in your project and therefore may be displayed on any mapsheet that covers a similar area to the data. Similarly a single mapsheet may be used to display any number of different display lists. Select File/SaveAs Name your display list MyMapFile. The default location for saving is the project directory in which you are currently working. Creating a Mapsheet using a Mouse Select MapSheet/Create/Using mouse/easting-northing Enter a meaningful name for the new mapsheet. Click OK. There are three basic ways to create mapsheets: 1. By manually entering details of your area of interest. 2. By using the mouse on a pre-existing map to drag a box around your area of interest. 3. By using the coordinate range of the data you wish to display on the map to define the area of interest. 16 Getting Started With Petrosys

17 The cursor will change to a cross and you can now drag a box that defines the extent of the new mapsheet. When you are happy with the shape of the new mapsheet click once with your left mouse button. A dialogue box allowing you to alter the appearance and refine the extent of your mapsheet appears. Enter the name My New Mapsheet in the Map title box and click OK. After clicking OK a dialogue box will be displayed that provides detailed information about the mapsheet you have created including the coordinate reference system (CRS) and geographic extent. Click OK in this dialogue box to finalise creation of your mapsheet. Getting Started With Petrosys 17

18 Your new map should be similar to the view shown above with the grid, wells and 2D seismic lines still displayed. Choose MapSheet/Save to save your new mapsheet. This illustrates the point that data in a display list (the grid, wells and 2D seismic) can be displayed on more than one mapsheet. Printing a Map Choose View/Print The dialogue box shown on the right will be displayed. Select the printer you wish to print from. Select an orientation that suits the layout of your map. If you are printing to a printer with a defined page size you may wish to check the Scale to page size box. Remember that any scaling operations will alter the scale of the map. Click OK. Linux/Solaris users can output directly to plotters using the View/Plot. command. The View/Plot... menu can also be used to create output in various raster image types (.jpeg,.png,.cgm, etc). 18 Getting Started With Petrosys

19 Creating Surface and Grid Contours In the main start-up panel of Petrosys click on the button labelled Grid, contour, volumetrics. The Gridding and Contouring dialogue box can also be accessed from the Interactive Mapping window by selecting Edit/Gridding&Contouring... The Gridding and Contouring dialogue box is displayed. Choose Grid/Create grid to open the Petrosys Gridding Control dialogue box. Getting Started With Petrosys 19

20 Click on the button beside Output grid and enter the name Top Valanginian. Click OK. The file suffix.gri will be added automatically. Click on the Input Data tab to bring up the Input Data To Grid dialogue box. 20 Getting Started With Petrosys

21 Click on Delete to remove any data sources currently selected. Click on the top-left icon (circled) to bring up the Data Source Selection dialogue box. Almost any common data type can be used as input to gridding including well data, seismic interpretation, spatial data, point data, contours, etc. Gridding and contouring can combine multiple data types from multiple data stores to produce a single output grid. In the dialogue box ensure that the variables are set as shown in the screenshot opposite. In order to select the SMT project you may need to add the connection - see page 7 for instructions. Click OK. You will be taken back to the Input Data to Grid dialogue box. Click OK to be taken back to the Petrosys Gridding Control dialogue box. Getting Started With Petrosys 21

22 Click on the Geometry tab and set the variables to be the same as those shown on the screenshot to the right. This instructs the software to create the surface grid over the area of the Targa Regional mapsheet and to have a cell size of 200m x 200m. 2 1 Click on the Faults tab (1) and set the variables to be the same as those shown on the screenshot opposite. Ensure the Use fault data box is checked (2). The fault file (twt.fal) is located in the project directory and can be accessed by clicking on the grey button beside Fault file. Petrosys can read fault data directly from many common data stores or can use fault data stored in a Petrosys fault file. 22 Getting Started With Petrosys

23 Click on the Contouring tab (1). Check the Use contouring box (2). The name of the Output contour file should already be present. If not, click the button beside it and name the output file Top Valanginian.con. Click OK to begin gridding and contouring. 2 1 The contour increment specified here determines the minimum contour increment that can be displayed on the map. The contour increment is fully editable and contours at specific levels can also be added. Contouring can be performed as a specific task without the need to recreate the grid from scratch. During the gridding and contouring process a record of the steps performed and the final outcome is displayed and kept in the text display box of the Gridding and Contouring dialogue box.

24 3D Viewer In the main start-up panel click 3d viewer. The 3D viewing part of the software should begin. Choose Display/Grid 24 Getting Started With Petrosys

25 In the Display grid dialogue box select the Top Valanginian.gri file that was created in the previous step. Change the Resolution to High using the sliding scale. Select Gradient color in the drop down box beside Surface color mode and select Petrosys default in the button beside Color gradient. Ensure that Z value scaling is set to Invert. Click OK. Choose Display/Wells, set the Data source to SMT and select the SMT database used earlier. Click OK. Display list map files and raster images can be displayed in the 3D viewer either on a 2D plane or associated and draped over a displayed surface. In this way, attribute maps may be easily viewed in conjunction with structural maps. Getting Started With Petrosys 25
