Users, roles, privelages

Oracle DB: 11.2.0.4

OS: Linux    

I am looking to produce a report for many Oracle Users similar to following two users. This will include all roles granted on all production schema( i.e. prod1_select_role, prod1_dml_role, etc.), grants on dictionary views, select or DML grants on any individual tables on other schema.tables, and any proxy user grants.

Example queries are appreciated. thanks you.
