There is a constant requirement to have data from ESRI ArcSDE, ArcMap and File Geodatabase made available to Schlumberger Petrel software. This is not the easiest of tasks. It would be good if FME could read ESRI data sources and convert them into a format suitable for Petrel.
Likewise, it would be nice to read Petrel data sources and have them made available in the ESRI environment
