Seleucid Satrapies?

I have my first bit for my upcoming timeline God Manifest written, but I am having trouble finding information on the administrative division of the Seleucid Empire. The structure of the government I have resources on, but what we know about what provinces were where I can’t find anything on at all. Does anyone have any sources they can point me to?
 
Here, does this help?

The Encyclopedia Iranica is always useful when it comes to Iranian history, but this article only covers the time from Cyrus to Alexander. Not exactly helpful except in the broad strokes, especially since the Seleucids were even more Mesopotamia-minded than the Achaemenids, or the Parthians for that matter.
