Sinopec wins approval for 235.7bcm Ziyang shale gas reserves
What happened
Sinopec received approval to develop the Ziyang Dongfeng ultra‑deep shale gas reserves in the Sichuan basin. The project targets reservoir intervals at roughly 4,500–5,200m, which makes drilling, completions and testing operationally demanding. Watch for FEED activity, prequalification rounds and mobilisation notices that indicate procurement demand is about to appear
Buyer takeaway
Treat this as a confirmed, long‑run sourcing program for extreme‑depth drilling and completions that requires early supplier gating and capability verification
Cost / money
Directional pressure toward higher short‑term premiums on specialist scopes where qualified contractors are scarce
Supplier / commercial
Suppliers with proven extreme‑depth experience will command tighter terms, limited bid windows and mobilisation premium requests
Safety / operations
Depth increases well‑control complexity; insist on documented extreme‑depth well‑control procedures, testing regimes and equipment certification
What to watch
Watch for rapid FEED launches and prequalification steps that will absorb specialist contractor capacity and shift mobilisation windows quickly
Key facts
- Targets reservoir intervals at roughly 4,500–5,200m depth
- Described as China’s first ultra‑deep shale field at this scale
- Project positioned to move into capacity growth and production planning
