ABSTRAK
IDENTIFIKASI KARAKTERISTIK RESERVOIR PANAS
BUMI LAPANGAN “P” BERDASARKAN ANALISIS SEISMIK

Lapangan Panas Bumi “P” merupakan area panas bumi yang terdiri dari dua
wilayah utama, yaitu Wayang-Windu dan Kencana-Sodongabig yang berdekatan
sehingga dimungkinkan memiliki sistem yang sama. Untuk mengetahui
karakteristik reservoir pada Lapangan Panas Bumi “P” melalui data katalog gempa
microearthquake hasil perekaman, dilakukan studi tomografi seismic dengan
menggunakan Software Lotos Tenerife Release Version. Event yang digunakan
untuk melakukan tomografi sebanyak 932 dari total 1455 event. Hasil pengolahan
didapatkan sebaran hiposenter hasil relokasi software Lotos Tenerife Release
Version, Tomogram Vp, Vs, dan Vp/Vs untuk mengidentifikasi area berdasarkan
struktur kecepatan gelombang seismiknya. Analisis dilakukan untuk mengetahui
nilai Vp pertubasi dan Vs pertubasi dari area penelitian, juga didukung oleh rasio
Vp/Vs area penelitian. Terakhir, dilakukan korelasi dari hasil analisis ketiga
komponen tersebut untuk mengetahui karakteristik reservoir daerah penelitian.
Kata kunci: Dua fasa, Gunung Kencana, Panas bumi, Reservoir, Wayang Windu.

ABSTRACT
IDENTIFICATION OF GEOTHERMAL RESERVOIR
CHARACTERISTIC OF “P” FIELD BASED ON TOMOGRAPHY
SEISMIC ANALYSIS

The “P” Geothermal Field is a geothermal area consisting of two main regions,
namely Wayang-Windu and Kencana-Sodongabig, which are adjacent to each
other and therefore likely to have similar systems. To find out the reservoir
characteristics in Geothermal Field “P” through the microearthquake catalog data
recorded, a seismic tomography study is made using Lotos Tenerife Release
Version software. The events used to perform tomography are 932 out of a total
1455. The processing results obtained hypocenter distribution of the relocation
results of Lotos Tenerife Release Version software, Tomogram Vp, Vs, and Vp/Vs
to identify areas based on the seismic wave velocity structure. An analysis is
conducted to determine the Vp and Vs values of the study area, supported by the
Vp/Vs ratio of the study area. Finally, a correlation is made between the results of
the analysis of these three components to determine the characteristics of the study
area reservoir.
Keywords: Geothermal, Microearthquake, Mount Kencana, Reservoir, Two phase.
