rewrite rules add a folder in the path

I think that portfolios and locations are two custom types right?

In this case you have to change the slug options inside the custom type registration:

register_post_type( 'portfolios', array(
    ...
    'rewrite' => array("slug" => "/production/portfolios", "with_front" => false),
) );
