Section Z merupakan salah satu dari tiga kompartemen utama dalam Struktur FIN
yang telah lebih dahulu dikembangkan melalui penerapan pola injeksi-produksi
(pattern) dalam kegiatan waterflooding. Dalam rangka melanjutkan optimasi
perolehan minyak, penyusunan pattern pada Section X dan Section Y menjadi
langkah strategis dalam persiapan perencanaan lapangan menuju implementasi
Enhanced Oil Recovery (EOR) full-scale, melalui perencanaan yang matang serta
evaluasi pelaksanaan monitoring dan surveillance kegiatan waterflooding pada
ketiga section tersebut.
Hasil evaluasi menjadi dasar perencanaan pengembangan lanjutan menuju tahap
Enhanced Oil Recovery (EOR) full-scale melalui penentuan pola sumur injeksi
produksi (pattern) yang optimal berdasarkan respons reservoir. Evaluasi dilakukan
dengan menganalisis Indeks Heterogenitas, Chan’s Diagnostic, Hall Plot, Voidage
Replacement Ratio(VRR), serta konektivitas antar sumur. Penelitian difokuskan
pada tiga lapisan dengan nilai remaining in place tertinggi dari masing-masing
section.
Berdasarkan hasil monitoring dan surveillance waterflooding, diperoleh
rekomendasi kandidat pola injeksi-produksi (pattern) sebagai usulan pilot project
EOR yang akan dilanjutkan ke tahap pengembangan skala penuh (full-scale).
Adapun pola yang direkomendasikan adalah: Section X menggunakan Pola
Irregular Inverted Five-Spot Pattern menunjukan kenaikan oil rate sebesar 92
bbl/day, Section Y menggunakan Pola Irregular Four-Spot Pattern menunjukan
kenaikan oil rate sebesar 38 bbl/day, dan Section Z juga menggunakan Pola
Irregular Five-Spot Pattern menunjukan kenaikan oil rate sebesar 47 bbl/day.
Selanjutnya, hasil screening metode EOR menurut Al-Adasani & Bai, 2010 dan
menggunakan Software EORgui menunjukkan bahwa metode Surfactant Polymer
(SP) dan Alkaline Surfactant Polymer (ASP) merupakan metode EOR yang paling
direkomendasikan untuk Struktur FIN, berdasarkan karakteristik batuan dan fluida
reservoir yang dianalisis.

ABSTRACT
PREPARATION FOR FIELD F DEVELOPMENT FOR FULL
SCALE EOR IMPLEMENTATION USING AN INTEGRATED
ANALYSIS APPROACH PT PERTAMINA HULU ROKAN

Section Z is one of the three main compartments within the FIN Structure that has
been previously developed through the application of an injection-production
pattern in waterflooding operations. To enhance oil recovery, the establishment of
optimized patterns in Section X and Section Y becomes a strategic step in field
development planning toward the full-scale implementation of Enhanced Oil
Recovery (EOR). This planning is supported by a comprehensive evaluation,
including monitoring and surveillance of waterflooding performance across all
three sections.
The evaluation results serve as the basis for planning further development toward
full-scale Enhanced Oil Recovery (EOR) by determining the optimal injection
production well pattern based on reservoir response. The evaluation includes
analysis of heterogeneity index, Chan’s Diagnostic Plot, Hall Plot, Voidage
Replacement Ratio (VRR), and injection-production well connectivity. The study
focuses on three reservoir layers, with the top three sections having the highest
remaining oil in place in each section.
Based on the results of waterflooding monitoring and surveillance, recommended
injection-production patterns were identified as candidates for an EOR pilot
project, which will be further developed into a full-scale implementation. The
recommended patterns are as follows: Section X uses an Irregular Inverted Five
Spot Pattern, showing an increase in oil rate of 92 bbl/day; Section Y applies an
Irregular Four-Spot Pattern, with an oil rate increase of 38 bbl/day; and Section Z
adopts an Irregular Five-Spot Pattern, resulting in an oil rate increase of 47
bbl/day. Furthermore, EOR method screening based on Al-Adasani & Bai (2010)
and the use of EORgui software indicates that Surfactant Polymer (SP) and
Alkaline-Surfactant Polymer (ASP) are the most recommended EOR methods for
the FIN Structure, based on the analyzed rock and fluid properties of the reservoir.
