f Microseismic Gravity Research for Delineation of Turbidite Reservoirs - A Status Report With Recent Field Data

We present the new data of the delineation of turbidite reservoirs and connected fault zones based on the simulataneous registration of the readings of a specially selected group of high precision gravimeters and measurement of natural microseisms. We discovered and investigated the phenomenon of influence of extremely low vibration (with the amplitude below 10 nanometers) on the position of the pendulum of sensitive system of high-precision gravimeters as early as 70-s. The influence of vibration was confined to the frequency band of 30-200 Hz and had a resonance character. We attempted to use the resonance reaction of different gravimeters to microseisms for the delineation of the hydrocarbon reservoirs (including turbidite ones).
