Changing DP size from 5″ to 5½

24 November 2009 My colleagues ..

I woud like to get your thoughts on the following :if we drill 10,000 ftTVD (12,000 ft MD) using 2000 HP rig
usually mud pump (3 X 1600 HP) with maximum surface pressure 4500 - 5000 psi. So, for hydraulics, we have a limitation of flow rate because of the surface pressure on limits on the mud pumps.

If we want to change DP size from 5" to 5½, are there any dis-advantages the change the DP size.?
what about HWDP --> do we must to change to 5½ ?
what kind of equipment that we must change to, if we change the DP size to 5½?
