Chepaizi High in W. Junggar Basin, commercial oil flow tested from the Carboniferous Tailegula fm, 1st such find in region.
Chetan 1 nfw. (PetroChina â Xinjiang) in Shamenzi Block, an important breakthrough, tested 119 bo/d and 0.22 MMcfg/d through a 6mm choke commercial oil flow in the Carboniferous Tailegula Fm. There are several oil fields found in this area, which has main reservoir in the Tertiary, Jurassic and Permian. A few wells penetrated Carboniferous reservoir, but no commercial oil has been achieved. Chetan 1 is the first well which makes a breakthrough in the Carboniferous and it indicates a significant potential prospective for carboniferous play in this area.
