Salam rekans, Ada yang pernah dengar atau mungkin punya pengalaman dengan tool yang namanya Infrasonic Passive Differential Spectroscopy (IPDS). Kalau saya lihat webnya Geodynamic research http://www.geonamics.com/index.html, claimnya sih lumayan fantastik juga, sebagai direct hydrocarbon cummulation indicator yang murah meriah baik untuk explorasi maupun development. Tapi koq kaya'nya too good to be true ya.... Ditunggu komen-komen nya. Cheers Oki Geospectra IPDS®
Seismic Passive method (non invasive) Active method (highly invasive) Detecting natural signals Detecting induced signals Micro-seismic / acoustic spectroscopy Seismic refraction & reflection (travel time and amplitude) No dispersion, no refraction, no absorption High dispersion, high refraction, high absorption Low frequency 0.1 - 8 Hz High frequency > 10 Hz Seismometer high sensitivity Geophone low sensitivity Detecting hydrocarbon fluids Detecting shape of rock formation (structure) Determine total net oil column Determine depth of structures Quick and accurate results with time and money savings Time and money consuming in complex areas Geospectra IPDS® Direct hydrocarbon detection method complements seismic data --------------------------------- Be a better friend, newshound, and know-it-all with Yahoo!
