Mubadala Petroleum has likely plugged and abandoned a new-field wildcat Nong Nuch-2, located offshore in the G11/48 concession, in the southern Pattani Trough, on 28 June 2019, as an oil and gas discovery. Spudded on 22 June 2019, the well was drilled to a total depth (TD) of 2,516 m using âEnsco 115â J/U, most likely targeting the Middle Miocene fluvial sandstone, which are also the producing reservoirs in the adjacent Bongkot and Nong Yao fields.  Located 20 km away from the Nong Yao and Bongkot fields, Nung Nuch-2 was drilled back to back with the previous newfield wildcat, Nong Nuch-1. Nung Nuch-1 was targeting a shallower reservoir than Nung Nuch-2, and the well has its TD at 1,015 m. Nung Nuch-1 was plugged and abandoned as a dry well.  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. 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%).    Nong Yao was brought onstream on 17 June 2015, with initial production rate of 2,500 bo/d. The field reached its peak production of around 10,500 bo/d in Q2 2016, after drilling four infill wells. Currently, the field is producing from 20 wells under an improved recovery regime. The gross production from Nong Yao field averaged about 7,110 bo/d in 2019.
