Tahap Kegiatan UP1. Survei Pendahuluan: geologi,

geofisika, dan geokimia untuk

memperkirakan letak dan adanyasumber daya & Wilayah Kerja.

2. Eksplorasi : geologi, geofisika,geokimia, pengeboran uji, danpengeboran sumur eksplorasiuntuk mendapatkan perkiraan

potensi Panas Bumi3. Studi Kelayakan: Informasi

secara rinci seluruh aspek untukmenentukan kelayakan usahapertambangan Panas Bumi,termasuk penyelidikan jumlah

cadangan yang dapatdieksploitasi

4. Eksploitasi: Pengeboran sumurpengembangan dan sumurreinjeksi, pembangunan fasilitaslapangan dan operasi produksi
