ResInsight can import well paths from simple Ascii files. In addition, ResInsight is able to retrieve well paths from an Equinor internal web service.
ResInsight also supports creation of your own user-defined well paths. See Create Well Paths
The command File -> Import -> Well Data -> Import Well Paths From File will read the well paths in the selected file, and create one entry for each well path under the Wells item in the Project Tree.
The supported ASCII format is quite flexible but the main requirements are:
"--" or "#"is considered to be comment lines
"'", "`", "´", "’" or "‘"the text between the quotation marks is used as a well name.

The well path 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.
If the well path file is changed and you would like a running ResInsight to update accordingly, you will need to delete all the well paths that emerge from that file, and import it again.
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 -> Well Data -> Import Well Paths From SSI-hub launches a wizard to guide you through the process of selecting the well paths 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 Wells item in the Project Tree.
The well path 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.
All the imported well paths are available below the Wells item in the Project Tree.
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 Paths. The Property Editor of the Wells item is shown below
A well path will hold well log data and well path data imported from files. A well path file is placed inside the well path item, while one or more well log files are placed as child items under the well path in the project tree.
Well log data is usually imported from LAS-files (*.las). LAS-files can be imported using the command: File->Import-> Well Data->Import Well Logs from File.
ResInsight will look for the the well name in the imported LAS-files among the existing Well Paths. If a match is found, the LAS-file is placed as a child of that well path. If not, a new empty well path entry is created with the imported LAS-file under it. A well path may have more than one LAS-files as children.
If the LAS-file does not contain a well name, the file name is used instead.
If ResInsight’s automatic well matching fails and a LAS-file is matched with the wrong well path, it is possible to move the LAS-file to the correct well path. Select the LAS-file right-click menu click Move LAS File to Well Path and select destination well path.
Well log names may vary slightly among different files from the same well. When importing a well log file or a well log path file, ResInsight have to look for an existing well path item to ensure that the well log data and well path are imported to the correct well path item. The lookup is based on name comparison this way:
The well path property editor lets the user control the appearance of the well path and associate the well path to a simulation well. It also gives some information about the well path metadata.
Some Casing Design elements can be assigned to the well path by selecting Create Casign Design from the right-click menu of the well path.
This will create a new child object for the Well Path, named Casing Design. In the Casign Design Property editor well path containment properties such as Casing (with Casing Shoe) and Liner can be added to the well path along with a start and end depth and a diameter.
These can be visualised in the 3D View and Well Log Plots on a Well Log Track.
