On 20 June 2019, Mubadala Petroleum plugged and abandoned a new-field wildcat Nong Nuch-1, located offshore in the G11/48 concession, in the Narathiwat Ridge, as a dry well. It is the first well ever drilled in the Narathiwat Ridge.  Spudded on 16 June 2019, the well was drilled to a total depth (TD) of 1,015 m using âEnsco 115â J/U, most likely targeting the Middle Miocene fluvial sandstone, an analogy to the producing reservoirs in the adjacent Bongkot and Nong Yao fields.  Previously in June 2019, the operator completed an appraisal drilling campaign in the Nong Yao field, on 12 June 2019. Three wells were drilled within 22 days from the same surface location, resulting in mixed outcomes.   Spudded on 22 May 2019, Nong Yao 9 and its first sidetrack well were likely plugged and abandoned after having encountered oil, most likely in the targeted Pattani Sequence III reservoir. Subsequently, Nong Yao 9ST2 well was kicked off on 7 June 2019 and abandoned as dry.  Interest in G11/48 concession is divided between Mubadala Petroleum (Thailand) Limited (90%, operator) and Palang Sophon (10%). Mubadala increased its stakes in the concession from 67.5% to 90% in June 2018, after acquiring an additional 22.5% interest from previous partner KrisEnergy for a consideration of USD 13.3 million.  Background Information  The G11/48 concession consists of seven other fields such as Nong Yao (producing under improved recovery regime) Nong Yao C, Nong Yao SW, Angun-1 (appraising) Boondarik-1, Bua Luang-1 and Mantana-1 (discoveries).  Pearl Oil (Thailand) Ltd and partners was officially awarded the G11/48 concession on 13 February 2007.
