| Summary: | Muara Laboh geothermal field is located in South Solok Regency, 150 km from <br />
<br />
<br />
<br />
<br />
Padang city. This field has been explored since 2007 and estimated to have a <br />
<br />
<br />
<br />
<br />
capacity of 220 Mw. In this field there are 6 wells and several geophysical data <br />
<br />
<br />
<br />
<br />
acquisition such as microseismic and magnetotelluric method has been performed. <br />
<br />
<br />
<br />
<br />
The Muara Laboh geothermal field status is on exploration stage and requires <br />
<br />
<br />
<br />
<br />
further information to enter the exploitation stage. Therefore the author models <br />
<br />
<br />
<br />
<br />
the velocity structure under the Muara Laboh reservoir. This study uses 135 <br />
<br />
<br />
<br />
<br />
microearthquakes data from September 14, 2010 to April 2, 2011 and 2692 <br />
<br />
<br />
<br />
<br />
microearthquakes from September 23, 2012 to December 22, 2013 with a total of <br />
<br />
<br />
<br />
<br />
2827. A microseismic earthquake was recorded on 32 scattered station networks. <br />
<br />
<br />
<br />
<br />
To maximize the result of picking waveform, the data is processed using the <br />
<br />
<br />
<br />
<br />
Master Event Cross Correlation method to update the catalog data and get more <br />
<br />
<br />
<br />
<br />
accurate results. Furthermore, the author used TomoDD software to produce <br />
<br />
<br />
<br />
<br />
hypocenter relocation and the 3D velocity structure under Muara Laboh's <br />
<br />
<br />
<br />
<br />
geothermal reservoir. The results of the 3D velocity model can be used to <br />
<br />
<br />
<br />
<br />
determine the structure and fluid phase under Muara Laboh geothermal field. |
