PT Northern Yamano Resources has completed drilling of wildcat Falah 1 in the East Pamai PSC, onshore Central Sumatra, according to local media in early May 2018. Well results were unreported.   Falah 1 is located in the Rumbai Bukit district, near Pekanbaru City, some 10 km south of the Minas field. Possible drilling targets could be Middle Eocene-Upper Oligocene sandstones of the Pematang Group and Lower-Middle Miocene sandstones of the Sihapas Group. Reportedly, the PTD of the well was approximately 1,600 m.  The well was spudded in early March 2018 and drilling operations were expected to be completed in approximately 21 days. Following Falah 1, the operator will reportedly drill a second well in the block, Falah NW 1.  The Falah prospect is estimated to contain resources of approximately 45 MMbo. Any commercial volumes discovered in the block would be likely allocated to local energy supply. A thanksgiving ceremony prior to the spud of Falah 1 was officiated by local authorities and SKK Migas representatives on 27 February 2018.   PT Northern Yamano is operator and sole interest holder in the East Pamai PSC.  Falah 1 is likely part of the original exploration commitments for the block. The operator initially issued a pre-qualification tender for integrated drilling services on Falah 1 in January 2015. A pre-drill site survey was conducted in late November 2016, and drilling was initially planned around May 2017.  No previous exploration activity has been carried out under the East Pamai PSC, which was officially awarded in 2009. The block includes acreage previously relinquished from the Rokan and Coastal Plains & Pekanbaru (CPP) PSCs.  Background Information    On 5 May 2009, the Indonesian government officially awarded the East Pamai PSC, located in the onshore Central Sumatra Basin, to PT Nana Yamano Technik during the 33rd Indonesia Petroleum Association Conference and Exhibition. The block was part of Phase II 2008 Tender Round and was offered under the Direct Offer mechanism. Bid documents were available from 10 November until 23 December 2008 with submissions accepted on 20 February 2009. The first three-year commitment amount to USD 6.4 million including geological and geophysical studies (USD 0.9 million), acquisition of 200 km 2D seismic data (USD 2 million) and drilling of one exploration well (USD 3.5 million). Signature bonus for the block was USD 1 million. The Domestic Market Obligation (DMO) fee was set at 25% and FTP was set at 20% (shareable).   This block is located in the Riau province in Central Sumatra and covers an area of approximately 1,870 sq km, surrounded by several existing PSCs, including CPP, Bentu and Rokan. Some 11 exploration well have been drilled within the block's limits. None of these wells found anything significant probably leading to this particular portion representing former acreage held under the Rokan PSC and CPP PSC.
