Pertamina EP has likely completed wildcat Kusuma Arum 1, in the Sumbagsel 2 PPC, located in the South Sumatra Basin, in late July 2020, with result unreported. Located near the Batanghari village, in the Ogan Komering Ulu Regency, the well was spudded around late November 2019, and had a planned total depth of around 2,300 m. The well was initially expected to be completed in three months.  The operator has estimated a pre-drill volume of around 60 Bcfg from this well. Typical exploration target in the block is the Talang Akar Formation, from which several fields in the area have been producing.  The last exploration drilling in the block was deeper pool wildcat Belimbing Deep 1 (gas shows), completed in February 2019. Located in the Belimbing Jaya village, Muara Enim Regency, the well was spudded around early November 2018, using PDSIâs Rig no.42 N-1500-E. Belimbing Deep 1 was likely targeting the pre-Tertiary Basement. The Talang Akar Formation, which is the producing reservoir in the Belimbing field, could have been a secondary objective for the well.  Prior to wildcat Belimbing Deep 1, the operator completed Sekarwangi 1 in late October 2018. The well may have encountered gas, however the three DST tests performed at depths of 3,218 m to 3,228m, 3,074 m to 3,080 m and 2,071 m to 2,074 m have likely shown intermittent flow. Spudded in May 2018, Sekarwangi 1 was drilled using PDSI-operated Rig no.42 N-1500-E. The well is located within the vicinity of Darmo village, in the Muara Enim Regency.  Pertamina holds 100% operatorship of the block.  Background Information  Pertamina spudded wildcat Sakura 1 in September 2017. The well with a PTD of 3,800 m, was targeting the deeper sandstones of the Upper Eocene-Lower Oligocene Lahat Formation, and secondarily the Upper Oligocene Talang Akar Formation. It is understood that the well encountered only minor gas indications.  In November 2017, the company likely completed a 2D seismic survey over the Selingsing area. As of June 2017, approximately 85% of the planned 608 km had been acquired. The survey was conducted by PT Elnusa. Acquisition commenced in January 2017. Over 50% of the acquisition had been completed as of February 2017. The seismic campaign was initially expected to last for approximately four months.  A socialization event to inform the local community about the planned survey was held on 6 October 2016. The survey covered areas in the vicinity of the Talang Akar-Pendopo field, within the Talang Ubi sub-district of South Sumatra Province. Preparations for the survey were ongoing in 2H 2015. In late 2014, Elnusa issued a pre-qualification tender for a subcontract related to the acquisition. Initial socialization activities with the locals were likewise conducted in late November 2014.
