Reconstruction of Conceptual Model in Mataloko Geothermal Field (Nusa Tenggara Timur)

Mataloko Geothermal field is administratively located in the Todabelu Village, Golewa District, Ngada, Nusa Tenggara Timur (NTT) within 10 km to the east-southeast of Bajawa, the capital Ngada. Shallow reservoir is located in the rock alteration were identified as claycap zone. The formation of the reservoir zones in claycap zone is caused by normal faults Wae Luja that pass through this area, where this fault which causes the formation of fractures in this zone and as a channel entry of fluid from the reservoir into the shallow reservoir.Development of conceptual model is started by interpreting geosciences data (geology, geochemistry, geophysics). The first step is reprocessing of Magnetotelluric (MT) data as the main data. It is then integrated with the analysis results of geology, geochemistry, geophysics data to generate a conceptual model. The evidence by the temperature wells around 287.8C from Geothermometer gas calculation (D'Amore dan Panichi).
