Press Release
            Supporting Massive Exploration, Elnusa Brings New
              Technology for East Pondok Aren Well Drilling
Jakarta, 15 December 2023 – PT Elnusa Tbk (Elnusa), a leading energy services company which is part of the Pertamina
Upstream Subholding, continues to support the government's efforts to encourage massive oil and gas (oil and gas)
exploration activities. Most recently, Elnusa contributed to the drilling activities of the East Pondok Aren exploration well
(EPN-001), the well drilling of which was carried out by PT Pertamina EP Regional Java Subholding Upstream Pertamina, in
Tambelang District, Bekasi Regency, West Java on August 18 2023.

Based on the latest information from PT Pertamina EP (PEP) Regional Java Subholding Upstream Pertamina, drilling of the
EPN-001 exploration well has successfully proven additional hydrocarbon resources. Pertamina EP President Director Wisnu
Hindadari said that his party consistently encourages exploration drilling in its working area to ensure the Reserve to
Production Ratio in the Java Region remains well maintained in the coming years. "EPN-001 is an exploration well that can
strengthen optimism in the search for new resources in areas that are classified as mature so that they can immediately
contribute to maintaining the carrying capacity of oil and gas production in the future," said Wisnu.

In terms of contract scope, Elnusa carries out perforation and pipe recovery activities. Perforation activity is the creation of
holes in the casing between the formation and the well so as to allow fluid from the formation to flow into the well. For the
first work, Elnusa was involved in perforation activities to repair cement bonding in the EPN-001 Well. Elnusa carried out
work for Tubing Conveyed Perforation (TCP) during the first Drill Stem Test (DST) on November 25 2023.

Elnusa Operations Director Charles Harianto Lumbantobing hopes that Elnusa's contribution to oil and gas exploration
activities in EPN-001 can contribute to positive results in efforts to discover new oil and gas potential from East Pondok Aren
so that it can help support the Government's target of achieving 1 million barrels per day of oil production and gas production.
amounting to 12 BSCFD in 2030.

"Elnusa certainly hopes that from drilling the EPN-001 exploration well there will be positive results in efforts to find new oil
and gas potential in the West Java area. "We also hope that Elnusa's contribution to Pertamina EP will continue in the future,
if there are development activities, we also want to continue to contribute on an ongoing basis," concluded Charles.
