The Special Task Force for Upstream Oil and Gas Business Activities (SKK Migas) noted a commitment to implementing Enhanced Oil Recovery (EOR) activities of up to the US $ 446 million.
EOR activities, especially in the Rokan Block, will support the achievement of the oil production target of 1 million barrels per day (BPD) by 2030.
EOR is an advanced oil recovery method by adding energy in the form of special material or fluid that is not contained in an oil reservoir. Generally, EOR is applied to fields that have long been produced (mature fields) with the aim of extracting remaining oil that cannot be produced by primary and secondary recovery methods (water flooding).
Some of the most widely known EOR techniques today are injection steam flooding, chemical flooding, and gas flooding.
Head of SKK Migas Dwi Soetjipto said the EOR activities to be carried out were water injection and chemical injection. To date, his party has recorded 23 EOR projects using polymers or surfactants which will operate until 2030.
"The firm work commitment (KKP) for EOR to date totals the US $ 466 million," he said.
Of the 23 EOR projects, his party will focus on its implementation in the Rokan Block.
In blocks whose management will shift to Pertamina in August 2021, his party will re-evaluate the existing plan of development / POD and steam injection projects such as in North Duri Development (NDD) 14, Duri Ring, and others. In addition, his party will encourage the completion of Chemical EOR Phase-1 at Minas Field in early 2022.
"The Minas field is the main support for the EOR strategy with an additional production of around 52 thousand BPD in 2030," said Dwi.
Regarding the progress of EOR implementation, 23 fields are still in the study stage. Meanwhile, one field is currently working on field trials and one field is being discussed on POD. Of the 23 EOR projects, most of them were Pertamina Group projects.
In details, PT Pertamina Hulu Rokan (PHR) will carry out 7 EOR projects, PT Pertamina EP 2 projects, PT Pertamina Ogan Komering 2 projects, PT Pertamina Hulu Energi Noth West Java (ONWJ) 2 projects, PT Pertamina Hulu Offshore South East Sumatra (OSES) 2 projects , PT Pertamina Hulu Energi Siak 1 project, PT Pertamina Hulu Mahakam 1 project, and PT Pertamina Hulu Energi Tuban 1 project. In addition, BOB Bumi Siak Pusako will work on 1 EOR project, PT Energi Mega Persada (EMP) 1 project, Medco EP Indonesia 1 project, and 1 Petrogas project.
Referring to SKK Migas data, the schedule for implementing one field (full field) for these EOR projects is Minas and Batang in 2024, Bekasap and E-main in 2025, Zulu in 2026, Tanjung, Rama, and Handil in 2027, Pedada, Sukowati, Gemah, Melibur, and Walio in 2028, Duri Ring, Bekasap, Kulin, Balam South, Bangko, and Kaji Harapan in 2029, as well as Air Serdang, Guruh, Krisna, and Mudi in 2030.
Director-General of Oil and Gas at the Ministry of Energy and Mineral Resources (ESDM), Tutuka Ariadji, said that the application of EOR technology is not easy. In order for this EOR project to run smoothly in the long term, a strong research and development institution is needed to support it.
"Backing up research and development is absolute. If there are strong research and development, we can monitor oil and gas production. The oil and gas industry needs technology and competent people. There is no compromise on that, "he said.
Meanwhile, Ronald Gunawan, Director of the Indonesia Petroleum Association (IPA), said that EOR activities are difficult to carry out under current conditions. This is because, with the current oil price conditions, the project is not economical when referring to the current fiscal scheme in Indonesia. If it is economical, oil and gas companies will certainly do it and boost oil production as much as possible.
