The success of this treatment largely depends on optimal proppant selection and placement, which directly influences fracture conductivity and well productivity. This study evaluates the optimization of hydraulic fracturing design through proppant mass sensitivity analysis in Well X, an offshore well located in East Java Province, Indonesia. Six scenarios with varying proppant masses ranging from 25,000 to 250,000 lb were analyzed to determine the most profitable design while considering Production Sharing Contract (PSC) Cost Recovery mechanisms. The research methodology integrates hydraulic fracturing simulation, production performance analysis through nodal analysis, and economic evaluation. The fracturing simulation results show improvements in fracture geometry and conductivity with increasing proppant mass, with Scenario 6 achieving the largest fracture half-length of 374.3 ft and conductivity of 3,100 ft.md. Nodal analysis reveals significant production enhancement, with oil rates increasing from 1,193.80 STB/D in Scenario 1 to 2,511.44 STB/D in Scenario 6. Economic evaluation under PSC terms indicates that Scenario 6 yields the highest NPV of 6.15 MMUSD with an IRR of 41% and the shortest payback period of 1.93 years (23 months). The study concludes that higher proppant mass treatments, despite increased initial investments, generate superior economic returns through enhanced production rates.

Sari Hydraulic fracturing merupakan teknik stimulasi sumur yang meningkatkan produksi hidrokarbon dengan menciptakan jalur konduktif pada formasi berpermeabilitas rendah melalui injeksi fluida bertekanan tinggi dan penempatan proppant. Keberhasilan stimulasi ini sangat bergantung pada pemilihan dan penempatan proppant yang optimal, yang secara langsung mempengaruhi konduktivitas rekahan dan produktivitas sumur. Penelitian ini mengevaluasi optimasi desain hydraulic fracturing melalui analisis sensitivitas massa proppant pada Sumur X, sumur lepas pantai yang berlokasi di Provinsi Jawa Timur, Indonesia. Enam skenario dengan variasi massa proppant mulai dari 25,000 hingga 250,000 lb dianalisis untuk menentukan desain yang paling menguntungkan dengan mempertimbangkan mekanisme Production Sharing Contract (PSC) Cost Recovery. Metodologi penelitian mengintegrasikan simulasi hydraulic fracturing, analisis kinerja produksi melalui analisis nodal, dan evaluasi ekonomi.
