Abstract
Passive seismic methods (microtremor hydrocarbons) is a seismic method that utilizes micro vibrations that come from nature. This method can be used to determine the movement of soil, volcanic activity, and monitoring the geothermal field. In its development, Passive seismic methods are used for hydrocarbon exploration. This method is very useful to be applied in the development of new fields before do seismic 2D/3D and avoid the risk of kindling dry hole. Passive seismic measurements have been carried out on the "No Play" field, Jambi Sub Basin, Jambi Province. Measurements using three seismometer components (east-west, north-south, and vertical) and Digital digitizer. Measurements were performed for 3 hours for every point. Data processing is done on a 4 point measurement. 1 point measurements were made near the well dry well and a point near the gas wells for the calibration well. And two measurement points in the area of the Field "No Play". The results generated microtremor wave character in the 3 components. On the horizontal components (east-west, north-south) shows the amplitude of the measurement in strengthening soft soil layer (peat soils), while the vertical component not found. Point of the vertical component of NP-2 2-5 Hz frequency spectrum obtained with a strong amplitude corresponding to the frequency spectrum of the calibration gas well and is indicated as a hydrocarbon reservoir. Keyword : Passive seismic, Hydrocarbon, Frequency Spectrum Metode passive seismic (mikrotremor hidrokarbon) merupakan metode seismik yang memanfaatkan getaran mikro yang bersumber dari alam. Metode ini dapat dimanfaatkan untuk mengetahui pergerakan lapisan tanah, aktifitas gunung api, dan monitoring pada lapangan panas bumi. Dalam perkembangannya metode Passive Seismic digunakan untuk ekplorasi hidrokarbon. Metode ini sangat bermanfaat untuk di terapkan pada pengembangan lapangan baru sebelum dilakukan seismik 2D/3D dan menghindari resiko pengeboran dry hole. Pengukuran passive seismic telah dilakukan pada lapangan “No Play” Sub Cekungan Jambi Provinsi Jambi. Pengukuran menggunakan seismometer 3 komponen (barat-timur, utara-selatan, dan vertikal) dan digitizer Digital. Pengukuran dilakukan selama 3 jam untuk setiap titiknya. Pengolahan data dilakukan pada 4 titik pengukuran. 1 titik pengukuran dilakukan didekat sumur dry well dan 1 titik di dekat sumur gas well untuk kalibrasi. Dan 2 titik pengukuran di area Lapangan “No Play”. Hasil penelitian dihasilkan karakter gelombang mikrotremor pada 3 komponen. Pada komponen horizontal (barat-timur, utara-selatan) menunjukkan penguatan amplitudo pada pengukuran di lapisan tanah lunak (tanah gambut) sedangkan pada komponen vertikal tidak ditemukan. Dari komponen vertikal titik NP-2 didapatkan spektrum frekuensi 2 - 5 Hz dengan amplitudo yang kuat yang sesuai dengan spektrum frekuensi kalibrasi gas well dan di indikasikan sebagai adanya reservoar hidrokarbon. Kata Kunci : Passive seismic, hidrokarbon, spektrum frekuensi
