JAKARTA (TheInsiderStories) – Indonesia’ state-owned oil and gas firm PT Pertamina conducts exploration activities by carrying out two dimensions (2D) seismic surveys in the Malacca Strait, Aceh along 1,800 kilometers, the company announced on Tuesday (07/9).

“The seismic survey is an important step for a subsidiary of PT Pertamina Hulu Energi (PHE) to contribute to supporting national energy security,” PHE’ managing director Meidawati said in a written statement.

Throughout 2018 until mid-2019, PHE has been drilling six exploration wells. Seismic activity at the exploration stage aims to find out the subsurface image which will be the basis of the petroleum system modeling to be able to find out the location of hydrocarbon accumulation along with the size of the reserves.

The 2D seismic sea activities cover two regions, namely East Aceh and North Aceh which are directly adjacent to Thai and Malaysian waters. The seismic results will confirm the potential for hydrocarbon accumulation which will become a mainstay field to hold back the rate of decline in production.

The potential for future hydrocarbon accumulation is projected to be a replacement field from the Arun Gas Field which once produced around 460 MMCFD. In exploration activities through seismic surveys, PHE North Sumatra Offshore (NSO) cooperates with PT Elnusa Tbk.

The plan, the seismic survey will be completed in July 2019. Furthermore, seismic results will be followed up with seismic processing, interpretation, and modeling so that it can be used in proposing exploration drilling wells to increase reserves.

Previously, the energy ministry extended the PHE contract in the NSO block. PHE NSO was given the trust to manage the NSO block for the next 20 years, namely 2038 with the gross split scheme, namely the production sharing contract scheme by eliminating the cost recovery that was effective from October 16, 2018.
