HYST Product Serves CNPC’s First 9000m+ Deep Well

On June 19, HYST’s premium connection casing was applied in CNPC’s first deep well with a designed depth of more than 9000m.

The well is known to have a designed depth of 9186m, located in north Tarim Basin, which is China’s demonstration area of efficient exploration and development of ultra-deep complex gas reservoir.

No cross threading and galling occurred in the whole process of casing running, and the make-up first-pass rate reached 100%, which was highly appreciated by the customer.
