PENGARUH SESAR NORMAL CEUNOHOT TERHADAP LANDAIAN TEMPERATUR SUMUR JBO-1 DAN JBO-2 DI LAPANGAN PANAS BUMI JABOI, SABANG, NANGGROE ACEH DARUSSALAM
Abstract
Sesar Ceunohot yang teridentifikasi dari survei geologi dan geofiska, memotong/melintang daerah prospek panas bumi Jaboi di antara Gunung Lemo Matee dan Gunung Semeureuguh dengan arah baratdaya – timurlaut. Sesar ini diduga menjadi media naiknya fluida panas bumi dari reservoir menuju permukaan. Hal ini didukung dengan data pengeboran sumur landaian suhu JBO-1 dan JBO-2.Dalam sumur JBO-1 didapati hilang sirkulasi sebesar 55,5 lpm di kedalaman 90,64 sampai 90,84 m dan sebesar 10 lpm pada kedalaman 172 sampai 238 m, dengan landaian suhu sekitar 21 °C. Dalam sumur JBO-2 didapati hilang sirkulasi dengan kisaran 30 sampai 350 lpm di zona kedalaman 21 sampai 43,15 m dan sebesar 30 lpm pada kedalaman 141 sampai 142 m, dengan landaian suhu sekitar 17 °C.
Tingginya temperatur gradient di sumur JBO-1 disesbbkan karena letaknya berada lebih dekat dengan zona rekahan sesar Ceunohot.
