PV Drilling jack-up drills longest well in Cuu Long Basin offshore Vietnam(12/15/2008)

PV DRILLING'S FIRST jack-up rig, PV Drilling-I, has accomplished several mile-stones in the drilling of well 9-2-CNV-2P, which was drilled to a total measured depth of 6,526 m. This depth represents the longest well drilled in the granite basement in the Cuu Long Basin in Vietnam to date.
 
An earlier success was recorded in the drilling of the 12.114-in. hole section of the same well to the top of granite basement. This was recorded as a significant operational accomplishment and proved that difficulties that have previously been encountered in drilling the deeper clastics sections at Ca Ngu Vang can be surmounted in future operations. "This again is clearly a direct result of the professional attitude and positive team work exhibited by the personnel who operate PV Drilling-I", said Ngo Huu Hai, general manager at Hoan Vu JOC, in a letter to PV Drilling CEO Do Van Khanh.

The latest achievement was made following the re-entry of the well, drilling to the original target total depth and then deepening the 8.112-in. hole section.
To reach the total depth of 6,526 m, a total of 2,238 m of granite was drilled. The final vertical depth of 4,608 m represents the deepest hole section drilled into the basement. Additionally, the drilling of the section from the previously drilled depth was completed five days ahead of schedule.

It is also recognized that these operational accomplishments have been made with an excellent HSE record and virtually zero mechanical down time or recordable NPT, according to Hoan Vu JOC.
