Petrel Introduction Cases Tab

Cases tabRunning a volume calculation will create a Case, which will have an icon in the case tab and a volume calculation sub icon. This will then become the filter for showing the results of the run in the plot window.

Cases and Results tabsThe design of Cases and Results tab is to allow the same setup for running ECLIPSE and Streamline simulation runs, as for running simple Volumetrics.


Petrel Introduction Workflows and Windows Tabs

Workflows tabStores workflows created by Process Manager for automated processes and operations.

Windows tabLists each windows and its settings. Can be saved or deleted.

Contains a set of variables that can be used in workflows.

A new workflow is inserted from the Insert menu

A new window is inserted from the Windows menu

Note: If a window becomes unresponsive, delete it and start a new one.

Petrel Introduction Project Settings and Units

1. Project infoGo to Project settings under Project Menu: Type in the UTM zone, Projection and Datum for the project. This is strictly informational.

2. UnitsSelect a standard Project Unit System from the drop-down menu (e.g. Metric or Field), or toggle Customize to set units from a mixed unit system.

Note: When importing data from OpenSpirit, make sure the Project settings in Petrel match those in the other data repository.

2

Note: There is NO unit conversion inside Petrel; it has to be done on import.


Petrel Introduction Object Settings – Style tab

The settings will ALWAYS include an Info tab and a Statistics tab. Most objects will also have a Style tab.

Every object has a Settings window that allows you to adjust parameters and view information about the object.

2. Go to Style tab to adjust display parameters. For example toggle on/off grid lines (A), contour lines (B) or color fill (C). Click Apply to view the updates.

1. To access the Settings tab, right-click on the object in the Explorer and select Settings (or double-click).

Petrel Introduction Object Settings – Statistics Tab

The statistics for each item can be checked under the Statistics tab.

List 2Describes different data and values related to the object.

List 1Describes the X, Y, Z coordinates; Z being depth or time. If an attribute is available it will also be shown.

One or both lists can be copied to an output sheet. Toggle on one of the lists (e.g. List 1) and click the output icon. The contents of the list will be written to an output window.


2A

Petrel Introduction Object Settings – Colors Tab (Templates)

1. The Colors tab displays the colors based on the template selected as the object was imported or generated.

2. The Colors template is linked to the same template in the Templates tab (A); any edits made here will affect the global template unless the lock (Info tab) for a specific object is on! (B).

Colors are related to the templates from Templates tab. These can be logs, depth, properties (continuous or discrete) etc.

Petrel Introduction Visualization – Toggle Boxes

Gray, square boxes – These are active when toggling objects to be displayed in windows (active or inactive depending on type of windows). Several objects in a folder can be displayed simultaneously.

Gray, circular “boxes” – You may only toggle on ONE at a time from a single folder.

Yellow, square boxes – These are Filters (not objects) and can be used to filter out different parts of a 3D grid (e.g. zones).

Filter color – Toggling off e.g. a zone (works as a filter) will make Zone Filter tick mark pink! (easy to see if filter is on even if folder is closed.

Note – Toggling on “Yellow” boxes in Global well logs folder, will have no effect unless a well with the same log is toggled.


Petrel Introduction Visualization – General Intersection (Create)

How to create a General Intersection (GI) Plane:

2. Select Insert General Intersection (A) and the toggle box in front of it automatically displays the plane (B).

1. Right-click on the Intersection folder in Models tab or on any regular folder in the Input tab.

Petrel Introduction Visualization – General Intersection (Move)

Two main methods for moving a General Intersection Plane:

1. Orient the plane by using Manipulate Plane icon located in the Function bar; left mouse to move; left mouse+ctrl pivots it in any 3D direction around its axis.

2. Orient the plane by using the Player at the bottom (active once GI is toggled on and bold).

“Blue button” for visualization on plane

Player options like Step, Play and Stop. The number indicates step increment in project units

Align plane e.g. North/South or East /West

Cut in front of or behind plane

Snap intersection by 1 (parallel) 2 or 3 points


Petrel Introduction Visualization – General Intersection (Display)

Note: When the “Blue button” is active, you cannot display any new objects in 3D.

After generating and moving the GI plane it is time to display data on the plane:

1. Make sure the correct GI plane is active.

1

2. Toggle the “Blue button” (A) to activate all objects that can be displayed on the GI plane,the toggle boxes will become blue (B)).

Petrel Introduction Visualization – General Intersection (Display)

The GI plane has Style settings to control visualization of Input and Model data on the GI. Right-click on the GI and select Settings. Here the color, transparency etc. is controlled from Plane settings tab. However, some style options are depending on how the GI was created, either from Input tab or Models tab:

Input tab

Models tab


Petrel Introduction Tips buttons

Many processes in Petrel contain small tips buttons (blue buttons with Question marks (?))

Each Tips button is related to one topic/algorithm/setting and is described in more detail, sometimes with explanatory pictures.

Use the tips buttons for quick information; further information can be found in the Online Manual (next slide)


Petrel Introduction Online Help-Manual

If there is any doubt regarding how to perform certain procedures (what algorithms to use, etc.), there is extensive documentation in the Online Help Manual.

Note: There are almost 500 “How to’s” in the Online Manual !

To access the Online Help Manual, go to Help menu – Manual (HTML help). The manual is included with your installation so a network connection is unnecessary
