The Hululais Geothermal Field is situated in Bengkulu Province, Indonesia. The permeability distributions of 24 wells exhibit varying characteristics. Identifying the reservoir permeability distribution necessitates the introduction of Ambient Noise Tomography (ANT) for studying the Rayleigh wave velocity structure. The acquisition of waveform seismic data employed 25 seismometers in 156 stations. Using the Neighborhood Algorithm (NA) inversion indicates the distribution of low Vs anomalies in the central and northern regions of the HGF field. It has a good correlation with the permeable zones under the control of fault. The high Vs anomaly which observed in the west and subsequently extends from the north to the south at -2500 to -3000 Meters a.s.l. interpreted as the basement rock. The low-velocity anomalies found in the shallow depth are associated with the presence of soft rocks. This is relevant to the low resistivity anomalies of Magnetotelluric on the surface as cap rock. The low-velocity anomalies at the deeper depth that are associated with the permeable zone are relevant to the presence of lost circulation zones in drilling wells. While the high-velocity anomalies associated with hard rocks are relevant to the absence of lost circulation zones in drilling wells. © 2025 The Royal Society of New Zealand.
