China: Ordos basin Sanjiaobei CBM well spuds

Sino Gas & Energy Holdings Ltd., Perth, has spudded the SJB1 coalbed methane appraisal well on the 1,100 sq km Sanjiaobei production sharing contract in the Ordos basin in China.

Sino Gas, operator in partnership with PetroChina CBM, shot 410 line-km of seismic on the PSC and selected the drillsite to evaluate and confirm the potential extension of productive pay zones encountered elsewhere on the acreage.

The well will be drilled to a total depth of around 2,100 m, logged, and cased in a process expected to take 30 days. Weather permitting, the rig will drill as many as two more wells on the Sanjiaobei PSC in 2011.
