Mubadala Petroleum plugged and abandoned the second well under the G01/48 exploration drilling campaign, Yothaka East 1, located in the Kra Sub-basin, Gulf of Thailand, on 5 December 2019, with minor oil. Located around 6 km southeast of Manora platform, the well was drilled to a total depth (TD) of 3,367 m within 6 days. The well encountered only thin sands (2-3 m) in the 600 series while there was no hydrocarbon show observed in the shallower 490 and 500 series.  The three-well drilling campaign commenced with the drilling of the Inthanin-1 well using "Valaris 115" J/U (formerly Ensco 115) on 20 November 2019. Located 3.7 km south-southwest of the Manora platform, the well was targeting the 400, 500 and 600 series sands. The Inthanin 1 well reached its TD of 2,528 m within four days, prior to being plugged and abandoned on 27 November 2019, as a dry well.  The third exploration well, Krissana 1, has been cancelled due to no shows in the shallower targets of 300, 400, 500 and 600 series sands. Priority is given to the prospects that are low cost to drill, quick to be developed, reachable from the existing platform and able to extend field life for several years. Another high graded prospect within the North Kra block, namely Manora DEFVX, is planned to be drilled in 2020.  The G01/48 concession is operated by Mubadala Petroleum with 60% interests through its subsidiary MP G1 (Thailand) Limited, partnered with Tap Oil (30%) and Northern Gulf Petroleum Pte Ltd (10%).   Background Information  The G01/48 concession was officially awarded to Occidental Exploration Pte Ltd (50%, operator) and partner Syarikat Borcos Shipping Sdn Bhd (50%) in December 2006. In 2007, Occidental was renamed to Northern Gulf Petroleum (NGP) Pte Ltd. Subsequently, Pearl Oil (later acquired by Mubadala Petroleum) acquired the entire 50% stake of Syarikat Borcos plus an additional 10% and operatorship from NGP.   In October 2010, Tap Oil acquired an indirect 30% interest in the block via the acquisition of a 75% share of NGP. In 2012, Tapâs indirect interest was converted into direct interest through transfer to subsidiary Tap Energy (Thailand) Pty Ltd. NGP retained the remaining 10% direct interest. Tap Oil elected to retain its stakes in the block after the completion of a full asset review conducted in 1H 2015.   From 2009 until 2017, six newfield-wildcats were drilled within the G01/48 concession, with three oil discoveries in Manora (2009), Malida 1 (2013) and Sri Trang 1 (2016).  The Manora oil field was discovered via Manora 1 wildcat in December 2009. The discovery was appraised by six oil wells and one dry well. Hydrocarbon discovery from Malida 1 enhances exploration potential between the new discovery and Manora field. A net pay of 9.5 m oil-bleed sandstone reservoir in the primary target between 2,396 to 2,412 m.  The last new-field wildcat in the G01/48 concession was drilled at the northern of the block, in late 2017. Ladawan-1 well was drilled to a total depth of 2,175 m TVDss, after having encountered an interpreted 3.3 m oil column at the 500 Sand Series. The well result is considered non-commercially viable and no well test has been carried out.   In mid-2018, Manora 8 ST1 well had successfully appraised the oil zones along the Manora East bounding fault. Located 2.2 km southwest of the Manora A platform, the well encountered a total net oil pay of around 93 m (based on logs interpretation) from the primary objective of the 490-60 Series sands, as well as new pools in the secondary objectives, 300 and 500 Series sands, plus minor pay in the 400 Series sands. The well result has contributed additional volumes of 1.1 and 1.9 MMbbl to the 1P and 2P reserves within the Manora field, respectively.
Yothaka E. 1 expl, 2nd of 3 wells planned, SE of Manora platform in G01/48, Pattani Tough / Kra Sub-basin, TMD=3367m, sidetrack planned as Yothaka E-2. A thin oil pay was interpreted on logs in the 600 series sands, however the other 400 + 500 target sands were dry.
