Abstract
Research using passive seismic methods has been performed on several oil fields around the world. In this study, the main result is the emergence of anomalous spectral frequency in range 2 - 6 Hz, at points measured just above the hydrocarbon reservoir. LCY-1 and LCY-2, both with hydrocarbon indications, were selected for analysis with passive seismic survey to delineate the extent of hydrocarbons in the "LCY" Field, Ombilin Basin West Sumatra. While the problem is limited to this research is the data used in the form of secondary passive seismic data processing performed using Matlab2010 software and mapping anomalous dispersion spectrum maximum value using software Surfer10. In the acquisition step, measurements were recorded at 13 locations: 2 points experimentally measured for 24 hours, 9 points measured pioneer for 3 hours and 2 exploration wells were measured for 3 hours. Based on the spectrum of anomalies arising at points of measurement, higher values of the spectrum occur in the South when compared with the North. This indicates potential for hydrocarbon accumulations are greater in the South. It can be concluded that the direction of migration of hydrocarbons in this basin is from NW to SE and this trend is supported by the structural framework in the area. Keywords: Matlab2010, passive seismic, petroleum system, maximum spectrum anomaly, Surfer10
