The Yixin-2 well reached a total depth at 4,165m in the Xu3 formation along with the Xu4 and Xu5 formations.
The wells were logged with Zitong-1 cased and cemented, while Yixin-2 is running casing before cementing.
Initial testing of the Zitong-1 well on the 70km² Guan structure is expected to begin in the Xu2 formation. At Yixin-2 an initial short-term flow test of the lower section of the Xu4 formation will be performed.
Ivanhoe Energy president and CEO David Dyck said that the Zitong block is highly prospective and has the potential for several trillion cubic feet of natural gas.
