Abstract

Identifikasi prospek dan lead pada Formasi Kujung Lapangan BTW, Cekungan Jawa Timur bagian timur, dilakukan dengan pemetaan geologi bawah permukaan berdasarkan interpretasi 30 lintasan seismik 2D dan satu data sumur. Pada bagian tenggara daerah telitian ditengarai adanya 2 (dua) prospek yakni PK-1 dan PK-2 serta satu lead LK-1. Penilaian resiko geologi (Pg) terhadap komponen sistem petroleum untuk masing-masing prospek dan lead memperoleh nilai Pg sebesar 0.27 untuk PK-1; PK-2 = 0,26, keduanya termasuk Low Risk untuk eksplorasi hidrokarbon, sedangkan LK-1 nilainya 0.18, termasuk Moderate Risk. Perhitungan volumetrik masing-masing prospek dan lead dengan simulasi Monte Carlo mendapatkan angka sumberdaya P50 jika terisi minyak, Prospek K-1 = 34.77 MBO; Prospek K-2 = 30.63 MBO; dan Lead K-1 = 5.60 MBO, sedangkan jika berisi gas maka besarnya sumberdaya P50 Prospek K-1 = 9561.19 MSCF; Prospek K-2 = 8423.01 MSCF; dan Lead K-1 = 1540.53 MSCF. Kata-kata kunci: prospek, lead, resiko geologi, dan sumberdaya. Identification of prospect and lead at Kujung Formation of BTW Field, eastern part of North East Java Basin, conducted with geology sub-surface mapping based on interpretation at 30 lines of seismic 2D and one well data. At the southeast of studies area were recognized of 2 prospects namely PK-1 and PK-2 also one LK-1 lead. Assessment of geological risk (Pg) for the components of petroleum system to the each prospect and lead obtain values of Pg equal to 0.27 for the PK-1; PK-2 = 0,26, both as a Low Risk for the exploration of hydrocarbon, while the LK-1 value is 0.18, as a Moderate Risk. Volumetric Calculation for each prospect and lead with Monte Carlo simulation show the number of resource P50 in oil case Prospect of K-1 = 34.77 MBO; Prospect of K-2 = 30.63 MBO; and K-1 Lead = 5.60 MBO, while if containing gas hence level of P50 Prospect of K-1 = 9561.19 MSCF; Prospect of K-2 = 8423.01 MSCF; and K-1 Lead = 1540.53 MSCF. Key words: prospect, lead, geological risk, and resources.
