BG Group E&P Brasil Ltda set a 2-1/2 mile string of 9-5/8" casing at 15,811 feet (4,819m) MDBRT (Measured Depth Below Rotary Table), 15,801 ft (4,816m) TVDBRT (True Vertical Depth Below Rotary Table), on well 1-BG-1-SPS in Santos Basin Block BM-S-13, offshore Brazil, utilizing Vetco Gray's world proven MS-700 Subsea Wellhead System. This is believed to be a record string length in Brazil waters.

The 9-5/8" casing string, hanger and MS-1 metal-to-metal seal were run with Vetco Gray's single trip High Capacity "Pressure Assisted Drillpipe Running Tool" and landed on V150 /NC-50 5" drillpipe using the semisubmersible Pride South Atlantic in 130m water depth. The 9-5/8" string incorporated a mixed P-110/Q-125 grade, 53.50 lbs/ft casing. Landing weight was 695kips (buoyed). The casing and MS-1 seal assembly were successfully tested to 7500psi.

BG's ongoing drilling operations also required a sidetrack phase which involved cutting and recovering a major portion of this initial, long 9-5/8" casing string, along with the Vetco hanger and MS-1 seal.

The 12-1/4" sidetrack section then required installation of a second 9-5/8" casing string, with the new 9-5/8" hanger and MS-E seal successfully landed, set and tested in the original sealing area in the 18-3/4" High Pressure Wellhead.

Vetco Gray Brazil was awarded this contract by BG E&P Brazil Ltda, a subsidiary of BG Group in mid-2005, to provide wellhead and tubular systems including rental tools and offshore services.

Vetco Gray has been providing sophisticated subsea wellheads and subsea tree systems from its Brazil operations for more than 30 years, with over 1,000 subsea wellheads and 180 subsea trees produced and installed there.

Vetco Gray would like to thank BG and all parties involved in this "First Class" operation.
