Indonesia’s PT Pertamina Hulu Energi (PHE), PT Pertamina’s upstream unit, said it has recorded its largest exploration reserve discovery in the past fifteen years. For 2024, Pertamina Upstream Subholding Group’s 2C contingent recoverable resources reached 652 million barrels of oil equivalent (MMboe) or 2C oil in place of 1.75 billion barrels of oil equivalent (Bboe), including existing structures reassessment evaluations, the company said in a news release. The 2C contingent resource discovery represents a significant increase compared to previous years, marking a growth of 34 percent, compared with the 2023 figure of 488 MMboe, Pertamina said. The contingent resource discovery was primarily driven by the company’s high impact discovery at the Tedong (TDG)-001 well, which holds 548 billion cubic feet of gas of 2C recoverable resources and 13.51 million barrels of condensate within the Pertamina EP Working Area, operated by PHE’s affiliate, PT Pertamina EP Cepu, in Region IV Zone 13, according to the release. The drilling of the Tedong (TDG)-001 well is part of a frontier area exploration initiative across five key locations: East Wolai (EWO)-001, West Wolai (WWO)-001, Julang Emas (JLE)-001, Yaki Emas (YKE)-001, and Tedong (TDG)-001. The initiative aims to confirm the hydrocarbon potential of the Minahaki and Tomori Formation Limestone, Pertamina said. Another significant discovery in Padang Pancuran (PPC)-1, located administratively in South Sumatra within the Jambi Merang Working Area, further contributed to the 2C contingent resources realization in the Pertamina Upstream Subholding Group last year. The PPC-1 well, drilled to a depth of 3,750 feet (1,143 meters), recorded 140.6 MMboe of 2C recoverable resources, the company stated. PHE completed drilling 22 exploration wells in 2024. Additionally, PHE conducted a 2D seismic survey covering 769 kilometers and a 3D seismic survey spanning 4,990 square kilometers. “This achievement is concrete evidence of our exploration team’s dedication and
