Abstract: A seismic recording system comprises a multichannel recorder connected to a cable formed from a plurality of signal conductors. Each of the signal conductors is connected to a different channel of the recorder. The cable has a plurality of takeouts located at spaced distances along its length. Each of the takeouts is connected to a different signal conductor of the cable. The system further includes a switch operably connected to one of the takeouts for selectively interconnecting the takeout and any one or more of several seismic detector connections upon receipt of a remotely generated signal. The system also includes a number of detector conduits, each of which has one end operably connected to a different one of the seismic detector connections of the switch. Each detector conduit has at least one geophone located along its length and operably connected thereto. A control is provided for transmitting a signal to a switch. The switch interconnects a selected group or groups of geophones with the recorder.

Each of the signal conductors is connected to a different channel of the recorder. The cable has a plurality of takeouts located at spaced distances along its length. Each of the takeouts is connected to a different signal conductor of the cable. The system further includes a first conduit operably connected to one of the takeouts. A plurality of remotely operable switch means are located along the length of the first conduit for selectively interconnecting the first conduit and a plurality of detector conduits upon receipt of a remotely generated signal. Each detector conduit has at least one geophone located along its length and operably connected thereto. A control means is provided for transmitting a signal to a selected switch means for interconnecting its associated detector conduit and geophones with the recorder.

Abstract: A seismic exploration method in which a coded energy signal is generated and transmitted into the earth, the seismic energy reflected from within the earth is sensed and sampled to form a raw trace, the raw trace is crosscorrelated with a record of the coded energy signal, and a predictive operator derived from the autocorrelation function of the coded energy signal is subtractively applied to the crosscorrelated trace to remove correlation residuals, and thereby produce a high quality processed trace. Geophysical principles are used to interpret the processed trace and identify subterranean mineral deposits of interest. Based on this interpretation at least one well is drilled to further explore and/or develop the mineral deposits of interest.
