IHS-Markit understands that Pertamina has likely plugged and abandoned new-field wildcat Radiatus Madu 1 (RDM-001), in the Nanggroe Aceh Darussalam (NAD) 1 PPC, onshore North Sumatra, in March 2019, as dry hole. The well was spudded on or around 31 December 2018, using PDSIâs âN110/59â land rig. The well was targeting oil and gas in the Middle-Upper Miocene Besitang River Sandstone, with a PTD of 2,125 m. Pre-drill resources for the Radiatus Madu prospect were estimated by Pertamina at 10.8 MMbbl and 62.8 Bcfg.    According to local reports, well operations were anticipated to require approximately 30 days for drilling and 38 days for completion and testing. Drilling cost for RDM-001 was reported at USD 13 million.  In preparation of the drilling, the operator held a socialization event with the local community of the West Brandan district, Langkat Regency, on 31 December 2018.  Pertamina was also conducting development drilling in the block, with the Rantau SZ24 (RNT-SZ24) well in Rantau field. The well was spudded on 29 December 2018, ahead of the initial planned 2019 schedule. The purpose of the well is to increase oil production from the field, responding to the government call for maintaining the national energy security.  Background Information    Previous exploration activity in the Nanggroe Aceh Darussalam 1 PPC was the drilling of wildcat Titanum 1 in 2018. The well is reported to have flowed a small amount of gas, as of July 2018. Well testing was ongoing in early January 2018. The well was spudded in late November 2017 using Pertamina Drilling Services Indonesiaâs (PDSI) 500 HP land rig.  The largest field in the block is Rantau, which started production in 1929 shortly after its discovery. The field is estimated to contain approximately 300 MMbo plus 400 Bscfg recoverable, from Upper Miocene Keutapang sands. The structure is a diapirically-controlled NW-SE gently-dipping faulted anticline with over 396 m of structural relief. Complex NE-SW cross faulting divides the structure into 12 fault blocks, with displacement varying from 5 to 20 m. The field was shut-in from 1941 to 1960. Improved recovery was implemented in 1982 while enhanced recovery commenced in 2010. Pertamina conducted new development drilling in the field in December 2018, targeting to reach a production rate from the field of 3,000 bo/d in early 2019.
