Mubadala Petroleum plugged and abandoned appraisal well Nong Nuch-4, located offshore in the G11/48 concession, in the Narathiwat Ridge, on 3 July 2019, with minor oil. The well was drilled to a total depth (TD) of 1,116 m, approximately 1,400 m shallower than its discovery well, Nong-Nuch-2. Spudded on 29 June 2019 using âEnsco 115â J/U, Nong Nuch-4 encountered 0.9 m of oil in the primary objective, most likely the Middle Miocene fluvial sandstone which is the producing reservoir in the adjacent Bongkot and Nong Yao fields.   Nong Nuch-4 was drilled back-to back with the new-field wildcat Nong Nuch-2 which was completed on 28 June 2019. Spudded on 22 June 2019, the discovery well was drilled to a TD of 2,516 m prior to being plugged and abandoned as an oil and gas discovery.   The first new-field wildcat, Nong Nuch-1 was also the first well drilled in the Narathiwat Ridge. It was drilled to a TD of 1,015 m from 16 until 20 June 2019, prior to being 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. The original G11/48 concession covers a surface area of 13,600 sq km.   In January 2010, Kris Energy completed the sale and purchase agreement to buy over 25% working interest in block G11/48 from Tana Resources, a wholly owned subsidiary of Tana Exploration LLC. After the transaction completed, interest in G11/48 are divided between Pearl Oil (Thailand) Limited (75%, Operator) and Kris Energy (25%).  Previously on 12 June 2019, the operator completed an appraisal drilling campaign in the Nong Yao field. 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.
