The S-16 well is a horizontal well with a thin oil column in the reservoir, and its production has been affected by uneven fluid influx near the heel section. The objectives of the study are to compare and analyze various ICD configurations and design the optimal configuration to maximize oil production and minimize water production. The study utilizes a flowchart methodology, starting with a literature review to establish the fundamental theories related to ICDs. Data collection, including reservoir models, production data, and well schematics, is obtained from PT Saka Energi Indonesia. The collected reservoir model is validated through history matching using tNavigator software. Production predictions are conducted from June 2019 to March 2023, considering segmentation based on porosity, permeability, and water saturation, as well as variations in ICD nozzle size. The analysis compares the performance of different ICD configurations based on predefined evaluation criteria. The S-16 well in the SOT field serves as a case study, with the existing ICD configuration acting as the base case. The study evaluates total oil and water production for various ICD configurations, considering different segmentations and nozzle sizes. The results highlight the optimal ICD configuration that maximizes cumulative oil production while minimizing water production in the S-16 well. This study concludes that maximum oil production is achieved by using water saturation segmentation with ICD nozzle sizes of 4 mm, 4 mm, 2.5 mm, 1.6 mm, and 2.5 mm from heel to toe, respectively. This configuration is recommended over other configurations. Keywords: Inflow Control Device (ICD), horizontal well, nozzle size Sari Studi ini bertujuan untuk mengevaluasi konfigurasi Inflow Control Device (ICD) yang berbeda guna meningkatkan produksi minyak dan meminimalkan produksi air di sumur S-16 di Lapangan SOT, Jawa Timur. Sumur S-16 adalah sumur horizontal dengan kolom minyak tipis di reservoirnya, dan produksinya terpengaruh oleh aliran fluida yang tidak merata di dekat bagian heel. Tujuan dari studi ini adalah membandingkan dan menganalisis berbagai konfigurasi ICD serta merancang konfigurasi optimal untuk memaksimalkan produksi minyak dan meminimalkan produksi air. Studi ini menggunakan metodologi sesuai diagram alir, dimulai dengan tinjauan pustaka untuk memahami teori- teori dasar terkait ICD. Pengumpulan data, termasuk model reservoir, data produksi, dan skematik sumur yang diperoleh dari PT Saka Energi Indonesia. Model reservoir yang terkumpul divalidasi melalui proses history matching menggunakan perangkat lunak tNavigator.
