In addition, a Statoil specific solution to retrieve Well Trajectories from their internal web service is implemented. ![]({{ site.baseurl }}/images/ResInsight_WellPathWithSimulationWell.png) ## Ascii Well Trajectories The command **File -> Import -> Import Well Paths From File** will read the well paths in the selected file, and create one entry for each trajectory under the ![]({{ site.baseurl }}/images/WellCollection.png) **Wells** item in the **Project Tree**. The supported ASCII format is quite flexible but the main requirements are: 1. Each data line must contain four numbers: X Y TVD MD separated with white-space. 2. A line starting with none-number-characters are ignored, unless : 1. If the line contains a pair of : ', `, ´, ’ or ‘ the text between the quotation marks is used as a well name. 2. If the line contains the case insensitive string "name " the rest of the line is used as a well name. 3. If a well name is found, a new well is created and the following data points ends up in it. ### Example 1: WELLNAME: WELL1 4507.0 5638.5 0.0 0.0 4507 5638.5 4628.6 1628.6 4297.4 5938.5 4632.4 1998.387 -999 WELLNAME: WELL2 5507.0 4638.5 0.0 0.0 5507 4638.5 3628.6 1628.6 5297.4 4938.5 3632.4 1998.387 -999 ### Example 2: X Y TVD MD Name Well_1 5507.0 4638.5 0.0 0.0 5507 4638.5 3628.6 1628.6 5297.4 4938.5 3632.4 1998.387 Name Well_2 5507.0 4638.5 0.0 0.0 5507 4638.5 3628.6 1628.6 5297.4 4938.5 3632.4 1998.387 The trajectory data is not copied into the ResInsight project as such. The project file only stores the file path, and the next time you open the project, ResInsight will try to read the well data from the file again. ## Importing from SSI-Hub (Internal Statoil web-service) In order to import from SSI-Hub, a project file must be present and stored to file. All imported well paths from the web service will be stored relative to this project file location. If no project file exists, the menu item is disabled. The command **File -> Import -> Import Well Paths From SSI-hub** launches a wizard to guide you through the process of selecting the well trajectories you need.
Access to web service
The import of well paths is using a web service. If you are a Statoil employee, make sure you have access to "EDM Landmark" and "EDM Compass".
After completing the wizard, the wells imported are accessible as Items under the ![]({{ site.baseurl }}/images/WellCollection.png) **Wells** item in the **Project Tree**. The trajectory data is not copied into the ResInsight project as such, but is stored in files in a directory called *ProjectFileName_wellpaths* in the same directory as your project file. ## Well Trajectory Visualization All the imported well trajectories are available below the ![]({{ site.baseurl }}/images/WellCollection.png) **Wells** item in the **Project Tree**. ![]({{ site.baseurl }}/images/WellsInTree.png) The visible wells are always shown in all the 3D Views in the complete project, so the toggles and settings control the overall project visibility of the Well Trajectories. The **Property Editor** of the **Wells** item is shown below ![]({{ site.baseurl }}/images/WellPathCollectionProperties.png) - **Global well path visibility** This option forces the well paths on or off, ignoring the individual settings unless it is set to Individual. - **Clip Well Paths** This option hides the top of the Well Trajectories to avoid displaying the very long lines from the reservoir to the sea surface. - **Well Path clipping depth distance** This number is the distance from the top of the reservoir to the clipping depth.
