# Create Well Paths

ResInsight lets the user create new/custom well paths by clicking in the 3D view. A self created well path will behave the same way as an ordinary imported well path.

### Building a well path

1. Right click Wells in the project tree
2. Select Create Well Path in the right-click menu. A new well node and a well targets node are created.
3. Click in the 3D view on locations where the well path will pass (targets). Note. A 3D object must be hit when clicking. Clicking in thin air will not work.
4. When finished placing targets, click on “Stop Picking Targets” in the property editor

Well targets property editor fields:

• Start Type - Specify well to start either at surface or at first target point.
• UTM Reference Point - Reference point. Defaults to the first target point clicked.
• Air Gap - Specify Air Gap, i.e. distance from Rotary Kelling Bushing to sea surface. Applies to well path export only.
• MD at First Target - Defines the measured depth at the first defined well target.
• Generate Target at Sea Level - Automatically create a target at sea level based on a reasonable well path from reservoir to sea level
• Well Targets: List of targets. Will have pink background when in picking state.
• Point - Target position relative to reference point.
• DL in - Dog leg inwards [degrees/30m].
• DL out - Dog leg outwards [degrees/30m].
• Dir - Check box for overriding well path auto calculated directions.
• Azi (deg) - Azimuth. Y axis is 0 degrees.
• Inc (deg) - Inclination. Z axis is 0 degrees.

A self created well path may be edited by either editing coordinates in the property editor or clicking and dragging targets in the 3D view.

Clicking and dragging the blue part of a target, it can be moved along the Z axis only. Clicking and dragging the magenta part of a target, it can be moved freely around.

### Starting well path at a fixed position

The toggle Generate Target at Sea Level is on by default. If the well path is supposed to start at a predefined location at the sea level, the following procedure can be used:

1. Right click Wells in the project tree
2. Select Create Well Path in the right-click menu. A new well node and a well targets node are created.
3. Clear Generate Target at Sea Level
4. Right-click in the pink well target area, and select Insert new Target above
5. In the UTM Reference Point field, enter the predefined UTM coordinate (usually, the depth is set to 0.0 for sea level)
6. Continue clicking on geometry in the 3D view to add more well targets and make sure the first well target is defined by [0.00 0.00 0.00] to make sure the first target is located at the predefined UTM reference position

### Well Plan

A well plan can be displayed by selecting Show Well Plan from the right-click menu of a generated well path.
