摘要： A method of monitoring acoustic activity in a formation from a wellbore includes positioning a flow manipulation device into the wellbore, the flow manipulation device defining a flow path through which fluid may flow. Fluid is then pumped into the wellbore and through the manipulation device. A sensor disposed near the manipulation device is then coupled to the formation, the formation is fractured with fluid, and acoustic events in the formation are detected with the sensor.

摘要： A technique facilitates performance of seismic profiling, such as three-dimensional vertical seismic profiling. A downhole acquisition system is provided with acoustic receivers designed to receive acoustic source signals. The firing of acoustic source signals is synchronized with the downhole acquisition system. Additionally, the firing of two or more acoustic source signals is controlled to provide simultaneous or nearly simultaneous timing of one acoustic source signal with respect to another acoustic source signal. A processing system is used to acquire and process a data stream of the initial shot and a data stream of the additional shot occurring simultaneously or nearly simultaneously.

摘要： A seismic cable for use in land applications is described. The cable includes seismic sensors for measuring seismic signals reflected from subterranean or subsea formations. The cable may be deployed in trenches dug in the survey region to provide adequate sensor coupling to ground. Sensor units may be inline with the cable and may further be disposed in slim casings, thus facilitating handling and deployment.

摘要： A seismic vibrator includes a baseplate having a surface configured to couple to a ground surface. A driver is coupled to the baseplate and is configured to move the baseplate in a vibratory manner. A decoupling system is coupled to a part of the baseplate other than the ground-contacting surface. The decoupling system includes a first layer having a Young's modulus greater than that of a second layer coupled to the first layer. The second layer is coupled to the baseplate. The Young's moduli, thicknesses and masses of the first and second layer are selected to provide the decoupling system with a resonant frequency of at most, a spatial aliasing frequency of seismic sensors deployed on the ground surface or a lowest seismic frequency of interest.

摘要： Methods and apparatus for borehole seismic survey are disclosed comprising a first seismic source under water at a first location and a second seismic source at a second, deeper location. Seismic signals from the seismic sources are recorded with synchronized sensors located in a borehole and source signature data are obtained by combining the recorded seismic signals such that low and high frequency content of the combined source signature data is extended relative to the source signature of the first seismic source and the second seismic source.
