Abstract: An improved seismic array is provided which has the capability to supply data to adjacent recording stations simultaneously. The seismic array has a plurality of seismic detector connection points, and a seismic detector is located at each seismic detector connection point. Dual weighting of the output of each seismic detector in thearray is achieved by connecting dual resistors to the output of each seismic detector. Two pairs of wires are also provided in the array, and one pair of wires interconnects one weighted output of each seismic detector to the first end of the array. The second pair of wires interconnects the second weighted output to the second end of the array. An amplifier is provided for use at either or both ends of the array, and a feedback network, including a resistor, is associated with the amplifier. The ratio of the value of the resistance in the feedback network to the weighting resistor at the seismic detector determines the magnitude of the signal appearing at the output of the amplifier from the response of that seismic detector. A Chebychev weighted array is achieved by a proper selection of resistor values.

Abstract: An improved seismic array is disclosed having a plurality of seismic detector connection points with a seismic detector at each seismic detector connection point. The output of each seismic detector in the array is weighted by providing first resistive weighting at each seismic detector connection point. The weighted output of all detectors in the array is provided to a first end of the array over a single pair of wires. An amplifier is additionally provided for connection to the pair of wires at the first end of the array, and the amplifier has feedback network, including a resistor. The ratio of the value of the resistance in the feedback network to the value of the weighting resistor at a seismic detector connection point determines the magnitude of the signal appearing at the output of the amplifier from the response from the seismic detector at that point. An array having bi-directional capabilities is achieved by providing second resistive weighting to the output of each seismic detector in the array and by providing a second pair of wires which interconnects this second weighted output of the detectors and which emerges from the second end of the array. A second amplifier is coupled to the pair of wires at the second end of the array, and this amplifier also has a feedback network including a resistor. The ratio of the value of the feedback resistor to the value of the second resistive weight at each seismic detector connection point determines the magnitude of the signal appearing at the output of the second amplifier from the response of the seismic detector at the seismic detector connection point. Chebychev weighting of the array response may be achieved by proper choice of the values of the feedback resistors and the weighting resistors at each seismic detector connection point.

Abstract: An improved seismic array and method of seismic exploration are provided which have the capability to supply data to separate recording stations simultaneously. The seismic array has a plurality of seismic detector connection points, and a seismic detector is located at each seismic detector connection point. The outputs of the seismic detectors are electrically isolated from each other, and weighting may be applied to the output of each seismic detector in the array. Two signal-carrying media are also provided in the array, and the weighted outputs of the seismic detectors are conveyed to the first end of the array over one signal-carrying medium and to the second end of the array over the second signal-carrying medium. A Chebychev weighted array is achieved by a proper selection of weighting.
