Connect Oracle 11g to proprietory OLEDB data source

Question

I have an Oracle 11g database, which connects to another Oracle database and has stored procedures to collect data from that source database. The source database is being replaced with a proprietory (OSISoft PI) database which has an OLEDB data provider and I have the task of maintaining the connection. So...

I can see lots of info about an Oracle OLEDB provider allowing Oracle to be a source but nothing about Oracle being a consumer. So...

Can Oracle 11g connect to an OLEDB data source in order for stored procedures in Oracle to query the OLEDB source?
