I am trying to integrate the person accounts between salesforce and eloqua. Can we integrate the custom object in eloqua with standard object in salesforce?

For example I have A,B,C person accounts in salesforce and x,y,z are the corresponding survey records in the surveys object.

I am trying to store the survey details in Eloqua. Is there any possibility of fetching the details from salesforce to eloqua's custom object.?

Thanks,

Madhuri.
