Exit Opps for O&G bankers?

Hi everyone, 

I'm going to be an O&G analyst at a BB and wanted to know what are the PE exit opps like (particularly if I don't want to be in Houston)? Are my only exit opps in Energy PE? I also know that some PE firms have generalist roles but do those prefer certain groups like M&A and LevFin more than coverage groups?  

I have also heard it's tougher to get PE jobs in NY and SF due to locational preferences esp if you're at a different regional office. 

Any help is greatly appreciated!
