Horiz shale gas well in Dingshan â Dongxi block, Qijiang District, Sichuan Basin, TMD 6,062m (4,248m TVD), reportedly tested 313,000 cum/d from 4,270m after fracking, the 1st high-yield flow achieved from below 4,200m in China. Target Wufeng + Longmaxi fmâs.
Dongye Shen 1 (Sinopec â Xinan 100%) is a horizontal nfw, targeting the Upper Ordovician Wufeng â Lower Silurian Longmaxi shale formations at burial depth of over 4,000 m, tested a high-yield gas flow of 313 Mcm/d from deep-buried depth 4270 m after fracking, this is the first well with high-yield gas flow achieved in a burial depth over 4200 m in China, it is also a breakthrough in the fracturing technology for the deep-buried depth over 4000 m shale gas well.
