CNPC completes Keshen-902 appraisal well in China

China National Petroleum Corp. (CNPC) has completed the Keshen-902 appraisal well in Tarim oil field at a depth of 8,038 m, 15 m deeper than the Keshen-7 well drilled on the same structural belt 4.3 km away in 2011.

CNPC says Keshen-902 is “by far” the deepest onshore well drilled in China, represents the largest completion depth in a 333.4 mm borehole, and represents the largest setting depth with 273 mm casings.

The well, which lies on the southwest wing of the Keshen-9 structural high in the Kelasu structural belt, was drilled over a period of 368 days, 380 fewer days than that of Keshen-7, CNPC says.

Keshen-902 was drilled by the 90002 Drilling Crew of CNPC Chuanqing Drilling Engineering Co. Ltd. using a domestically developed 9,000 m electrical drilling rig.
