Pengtan 1 flow tested approximately 43 MMcfg/d from the Sinian Second Member of the Dengying Formation after acidization on 4 May 2020. Pengtan 1 was spudded on 24 June 2019 and was drilled to a TD of 6,373m MD on 19 January 2020. The success of Pengtan 1 confirms the hydrocarbon potential of the eastern Deyang-Anyue Fault Zone in the central Sichuan Basin, northeast of the Gaoshiti-Moxi Gas Field. PetroChina estimated that the reservoir area covers approximately 2,000 sq km and contains resources-in-place of greater than 35 Tcfg. Pengtan 1 is in the PetroChina operated Yanting-Daying Block in the Sichuan Basin and is geographically located within Sichuan Province, Daying County, Tianbao Town, Daowan Village. 
Pengtan 1 nfw. (PetroChina â Sichuan 100%) Anyue gasfield area, E. Deyang-Anyue fault zone, tested 43 MMcfg/d from the Dengying 2 fm, 127m pay encountered, potential > 35Tcf in place. TD=6 376m. The Pengtan structure, which covers 1200 kmÂ² in the central part of the basin, has the potential to hold more than âa trillion cubic metresâ of gas in place, the company said.
