Pengujian permeabilitas menggunakan metode <em>Constant Head Permeability Test</em> (berdasarkan Hukum Darcy untuk aliran fluida satu fasa), sedangkan analisis ukuran butir menggunakan metode sieve analysis dengan mesin <em>electric sieve shaker</em>.</p> <p><strong>Hasil –</strong> Hasil pengujian menunjukkan bahwa nilai permeabilitas rata-rata pada sampel 300 gram sebesar 1,35 mD dan pada sampel 400gram sebesar 0,84 mD, yang dikategorikan sebagai permeabilitas rendah (ketat). Analisis ukuran butir menunjukkan bahwa sampel 300 gram memiliki karakteristik pemilahan (<em>sorting</em>) yang moderat, sedangkan sampel 400 gram menunjukkan pemilahan yang buruk hingga sangat buruk. Keberadaan variasi ukuran butir dan proporsi fraksi halus menyebabkan penyumbatan rongga pori (pore throat constriction) yang menurunkan nilai porositas (berkisar antara 34% hingga 41% dari perhitungan volume pori dan bulk) serta membatasi laju alir fluida.</p> <p><strong>Orisinalitas/nilai –</strong> Berdasarkan parameter fisik yang diukur, interval kedalaman tersebut pada sumur "XN" diindikasikan memiliki karakteristik kualitas reservoir yang terbatas (<em>poor reservoir quality</em>).</p> Novi Dwiartika Reni Yudit Sirupang Copyright (c) 2026 Novi Dwiartika Reni, Yudit Sirupang https://creativecommons.org/licenses/by-sa/4.0 2026-11-12 2026-11-12 6 5 841 848 10.53866/jimi.v6i5.1572
