1.1 PetrelDirect

PetrelDirect is an OpendTect Pro feature for direct data transfer between OpendTect and Petrel* projects. Reading data from a Petrel* project is available in various OpendTect workflows via insert icon , which allows to either access data directly from a Petrel* data store via links or physically copy data to an OpendTect project. Either method gives full potential for manipulation, interpretation and processing. Writing data to a Petrel* project is also available in various OpendTect workflows by choosing PetrelDirect output format.

Survey > Import and Survey > Export menus have PetrelDirect option for supported objects.

Full two-way access (Petrel* <> OpendTect):

• Faults (since 6.0.4 release) and FaultStickSets
• 3D horizons
• 2D and 3D seismic
• Wavelets
• Wells (tracks, time-depth models and logs)

One way access (Petrel* > OpendTect):

• 2D horizons
• 3D prestack seismic
• Wells (markers)

The images below show an example of an OpendTect project with key data being read directly from the Petrel* data store.

PetrelDirect status button (in the lower right corner of the main OpendTect window) helps to monitor the status of the connection to Petrel*. Pushing the button will lead to the Settings Window. The drop-down menu next to it allows to directly control the status of the connection:

• - disabled (drop-down menu next to it allows to Enable connection)
• - uninitialized (connection is enabled, i.e. will be activated once PetrelDirect is used; drop-down menu next to it allows to either Disable connection or Initialize now)
• - active (drop-down menu next to it allows to Disable connection)
