Integrity of DV Collar

Lectori Salutem,
I was wondering if the members of the forum could share their opinion on whether a DV collar is viewed as a potential leak path or not - assuming it is successfully employed (no problems opening / closing and positive pressure test).
Also, does anyone have access to track record of failures or success of DV collars.
It would also be interesting to hear what your companies policy or standard is if a DV collar is used in a production casing string. Does your policy / standard require the DV collar to be covered by the liner lap?
Many thanks in advance,
Harald Benning
