Largest Gas Discovery in Indonesia in 18 Years
In February 2019 Repsol announced that its Kali Berau Dalam-2X (KBD-2X) well had found at least 2 Tcf of recoverable gas, making it the largest discovery in Indonesia for 18 years – since the Cepu discovery in 2001 – and one of the ten biggest finds in the world in the last 12 months. Prior to drilling, the prospect was estimated to hold in the region of 1.5 Tcfg, or over 250 MMboe. KBD-2X is in the 4.7 hectare Sakakemang Block, about 100 km north-west of Palembang on the southern part of the Indonesian island of Sumatra. The original well in the prospect, which targeted the pre-Tertiary fractured basement play, had well control issues and was re-entered earlier this year. It is hoped that this discovery will bring a much needed boost to Indonesia’s energy supply situation, particularly as it lies only 25 km from the Grissik gas plant, which gathers and processes production primarily from ConocoPhilips-operated Corridor PSC, where supply is expected to start to decline from 2024.
As operator, Repsol holds a 45% stake in the permit. Its partners are Petronas, which farmed into 45% of the block in January 2019 and MOECO, with 10%. Repsol holds several licenses in Sumatra, both onshore and offshore, and plans to execute an intense drilling and seismic acquisition campaign during 2019 and 2020.
