ANALISIS STIMULASI MATRIKS ACIDIZING BERDASARKAN DECLINE CURVE ANALYSIS PADA RESERVOIR SANDSTONE

WILLY CHANDRA - Personal Name; Novrianti - Personal Name;

Reservoir batu pasir (sandstone) rentan mengalami penurunan produktivitas akibat terbentuknya endapan scale di zona near-wellbore. Masalah ini menghambat aliran fluida dan menurunkan laju produksi minyak. Penelitian ini bertujuan menganalisis laju alir produksi menggunakan metode Decline Curve Analysis (DCA) dan mengevaluasi efektivitas desain matrix acidizing dalam mengatasi scale. Tiga model DCA eksponensial, hiperbolik, dan harmonic digunakan untuk memprediksi performa produksi sebelum dan sesudah stimulasi. Hasil menunjukkan bahwa model hiperbolik paling representatif dalam memperkirakan umur sumur dan produksi kumulatif. Sementara itu, desain matrix acidizing mencakup perhitungan tekanan fraktur, laju injeksi, serta volume dan durasi injeksi asam. Diperoleh kebutuhan volume asam sebesar 114,3 bbl dengan laju injeksi optimal 3,71 bpm. Stimulasi meningkatkan indeks produktivitas dari 0,7 menjadi 2,0 STB/d/psi dan menurunkan skin factor dari +40 menjadi -1,5. Hal ini menunjukkan bahwa matrix acidizing efektif dalam melarutkan scale dan meningkatkan performa produksi sumur sandstone
