Check below one,
IS-OIL -Downstream has mainly two areas and one is IS-OIL MM related and other IS-OIL SD related,although IS-OIL has their own components but those components are closely linked with MM and SD.
IS-OIL upstream has 4 different units.
IS-OIL -UPS -PRA (Production Revenue and Accouting)
IS-OIL UPS JVA ( Joint Venture accouting)
IS-OIL UPSRLM( Remote logistics Management)
IS-OIL UPS PSA(Production Sharing Accounting).
As you have mentioned that you have SD knowledge with you,I will suggest you to look for SRM in place of industry solution as that will have wide scope than IS-OIL.
IS-OIL PRA is only US specfic product and if you see whole SAP world ,there are smaller implementations for OIL solutions.
