20K Wellhead Systems to be installed in 2013 • Quotes currently out for 12+ 20K wellhead systems 03/20/2013 UWD HC-20 Subsea Wellhead System 30 15 Why Operators Are Choosing 20K Wellhead Systems • Increased Casing Capacity (Longer, Heavier Casing Strings Possible) o Starting to see 1,000,000+ lbs string weights for each casing hanger inside of the wellhead due to industry shift to 14” heavy wall casing o 2,000,000 lbs of casing capacity available in each of the 16” Submudline, 14”, and 11”-10 ¾” casing strings • Increased Temperature Rating o Metal Annulus Seal Assemblies rated for 350F o Elastomer Annulus Seal Assembly (Emergency) rated for 300F • Working Pressure of 20,000 psi o Shut-in pressure calculations are indicating pressures could reach or exceed 15,000 psi at the wellhead (conservative) o Newer fields have seismic data indicating production pressures greater than 15,000 psi 03/20/2013 UWD HC-20 Subsea Wellhead System 31 16
