Abstract
Penelitian ini berfokus pada analisis petrofisika untuk mengevaluasi parameter petrofisika Formasi Plover di Lapangan Poseidon, Cekungan Northwest Australia. Porositas, kandungan lumpur, saturasi air, dan permeabilitas diidentifikasi dalam delapan sumur yang diamati, berupa Poseidon 1, Pharos, Poseidon 2, Torosa, Kronos, Proteus, dan Boreas. Parameter yang dievaluasi termasuk porositas, kandungan shale, saturasi air, dan permeabilitas. Porositas dan permeabilitas dihitung menggunakan log densitas dan neutron serta persamaan Timur, sementara saturasi air menggunakan persamaan Indonesia. Hasil menunjukkan variasi porositas dari 5% hingga 43,76% dan permeabilitas dari 0,02 mD hingga 9923 mD, mengindikasikan heterogenitas yang signifikan dalam karakteristik reservoir. Pemodelan petrofisika yang terintegrasi menunjukkan bahwa pada zona target memiliki potensi tinggi sebagai target pengeboran baru, dengan nilai net pay yang tinggi dan karakteristik reservoir yang optimal seperti porositas efektif tinggi, volume shale rendah, saturasi air rendah, dan permeabilitas yang baik. Analisis ini memfasilitasi pemilihan titik prospek sumur baru, meningkatkan potensi eksplorasi dan produksi hidrokarbon di wilayah tersebut. Validitas dari model ini didukung oleh kedekatan dengan sumur eksisting, yang memungkinkan integrasi data yang lebih baik dan akurasi pemodelan yang lebih tinggi.

This study focuses on petrophysical analysis to evaluate the petrophysical parameters of the Plover Formation in the Poseidon Field, Northwest Australia Basin. Porosity, shale content, water saturation, and permeability were identified in seven observed wells are Poseidon 1, Pharos, Poseidon 2, Torosa, Kronos, Proteus, and Boreas. Porosity and permeability were calculated using density and neutron logs and the Timur equation, while water saturation was calculated using the Indonesian equation. Results showed porosity variations from 5% to 43.76% and permeability from 0.02 mD to 9923 mD, indicating significant heterogeneity in reservoir characteristics. Integrated petrophysical modeling indicated that Zone 1 has high potential as a new drilling target, with high net pay values and optimal reservoir characteristics such as high effective porosity, low shale volume, low water saturation, and good permeability. This analysis facilitates the selection of new well prospect locations, enhancing the potential for hydrocarbon exploration and production in the area. The model's validity is supported by its proximity to existing wells, allowing for better data integration and higher modeling accuracy.
