Pertamina Officially Inaugurates the Minas Rokan Field Chemical EOR Project

JAKARTA - PT Pertamina Hulu Rokan (PHR) inaugurated the Minas Area A Field Chemical Enhanced Oil Recovery (CEOR) Project, in the Rokan Zone.

The Minas field, which has been producing since 1952, is a mature field category but still has large reserve potential below the surface. Through the CEOR technology, PHR targets an increase in oil recovery of 12 to 16 percent from the Original Oil in Place (OOIP).

Head of the Special Working Unit for Upstream Oil and Gas Business Activities (SKK Migas) Djoko Siswanto emphasized that the Minas field is one of the most important assets in the history of the Indonesian upstream oil and gas industry, which for decades has made a real contribution to meeting national energy needs.

"However, we are also aware that Minas is a mature field. The sustainability of its production can only be maintained through innovation and the application of the right technology. Therefore, we are grateful that today we can inaugurate the implementation of Chemical EOR Phase I in Area A of the Minas Field," said Djoko, Wednesday, December 24.

Representing the people of Riau, the Acting Governor of Riau SF Haryanto fully supports the CEOR project in the Minas field as a strengthening of the synergy between the regional and central governments in managing sustainable energy.

He hopes that the increase in production from this technology will have a positive impact on the sustainability of the Oil and Gas Revenue Sharing Fund (DBH). This fund will return to the people of Riau in the form of road, school, and health facility development.

Through the Upstream Oil and Gas Acceleration Task Force, the Riau Provincial Government is committed and continues to strive to create a conducive operating climate.

"We are here as a strategic partner to facilitate cross-sectoral coordination, ensure investment security, and provide full support so that upstream oil and gas operations in Riau can run safely and optimally," he said.

Globally, CEOR technology has been applied by the world's leading energy companies. The success of CEOR, especially in mature fields, proves that technological innovation is able to extend the life of the field, increase the recovery factor, and strengthen national energy resilience.

"In this context, the success of the development of CEOR in the Rokan Working Area is not only a technical achievement, but also a symbol of Pertamina's transformation in managing upstream assets in a superior, globally competitive, and sustainable manner, and further strengthening Pertamina as a world-class oil and gas company," said Deputy President Director of PT Pertamina (Persero) Oki Muraza.

In the CEOR PHR Project, chemicals are used which are a combination of 3 chemicals, namely alkali, surfactant, and polymer (ASP) which are injected into the reservoir to sweep the oil out of the rock pores.

"What we should be proud of together, the surfactant as the main component in this CEOR technology is the result of the innovation of Pertamina officers. Its effectiveness has gone through a series of tests both in the laboratory and in the field, thus ensuring the reliability and readiness of this technology to be applied commercially," continued Oki Muraza.

The implementation of CEOR in Minas Area A on a commercial scale makes PHR a pioneer of CEOR technology in Indonesia. The success of this project does not stop at one area only, but will open up opportunities for the development of CEOR in other areas in the Rokan Working Area, such as Minas Area B, C, and D, Balam South, Balam, Bangko, to Petani.

In terms of production, the CEOR project is expected to contribute around 70 thousand barrels of oil per day (bph) by 2030, and reach a peak production of up to 200 thousand barrels of oil per day (bph) by 2036.

This achievement will certainly have a significant impact, not only on the performance of Pertamina and PHR, but also on national energy security, state revenue, and strengthening domestic technology capacity.

The Minas field, known as a producer of Sumatra Light Crude, has an area of 204.37 km², with 1,243 active wells and an average daily production of 29 thousand barrels of oil per day (bph). All production from the Rokan Zone is piped to the Hydrocarbon Transportation (HCT) Crude Oil Terminal Operation Center in Dumai, before being distributed to Pertamina refineries.
