Milestones 2018

New exploration block, new development wells, and an important discovery:

  • The onshore exploration block in South East Jambi has been formally awarded to Repsol, where the company will act as operator with 67% interest; Mitsui Oil Exploration will be the other partner.
  • Three development wells were completed in the Corridor block, one in the Sumpal field and two in the Suban field. Twp of these wells (Sumpal-8 and Suban-16) were producing in 2018; the third (Suban-18) will be tied in by the end of the first quarter in 2019. The Compression project in the Suban field has surpassed 80% progress rate, and start-up is expected to take place during the second half of 2019.
  • In February 2019, the important discovery of the Kaliberau Dalam-2X (KBD-2X) has been announced, in the Sakakemang onshore block located in the south of Sumatra island (Indonesia), where Repsol is the operating company with 45% interest. The preliminary estimates of recoverable resources point to around two trillion cubic feet (TCF) of gas, which makes this one of the major hydrocarbon discoveries in the world during the last twelve months and the greatest gas discovery in Indonesia in the last 18 years.
