MENENTUKAN SISTEM SESAR DI AREA PROSPEK PANAS BUMI MENGGUNAKAN METODE GAYABERAT

PIT API 2011

Gravity methods have the sensitivity to the changes in the horizontal anomaly.  Geothermal areas are generally found fault system.  This paper discusses the determination of fault using gravity method.  To find a fault on a trajectory of gravity done First Horizontal Derivative (FHD).  First Horizontal Derivative (FHD) may indicate the presence of horizontal density contrast limit contacts which indicate a fault.  Second Horizontal Derivative (SHD) was performed on the contact boundary area density contrasts that indicate a fault.  Value of SHDmax > |SHDmin| indicating the reverse fault.  SHDmax < |SHDmin| indicating the normal fault.
