PHE Metana Tanjung II announced on Monday it has completed the drilling of three exploration wells and five pilot/dewatering wells in Tanjung II CBM PSC in South Kalimantan.
Tonny S.Priantoro, General Manager of PHE Metana Tanjung II, said the drilling campaign has been carried out since 2012.
Three coal seams were found during exploration drilling at Warukin Atas formation, namely Seam A, B and C.
The discovery was followed by drilling of pilot/dewatering wells by making four wells as cluster around TJ-2-CBM-002 exploration well. The drilling of four wells and re-entry of the TJ-2-CBM-002 well was carried out in 2014 and 2015 with zero accident and cost efficiency of 35 percent.
With regards the five pilot/dewatering wells, PHE used Cased Hole Perforation at TJ-2-CBM-P4 and TJ-2-CBM-002P wells as completion method, followed by fracturing. Thus far, there are two wells -- TJ-2-CBM-002P and TJ-2-CBM-P4 ? which have flowed methane gas (CH4).
The Tanjung II CBM PSC, which is wholly owned by PHE, covers a total area of 1,092 sq km spanning the regencies of Tabalong, Balangan, Hulu Sungai Tengah, Hulu Sungai Utara dan Barito Utara in South Kalimantan.
