Abstract
1,173,358. Processing seismic data. TEXACO DEVELOPMENT CORP. 30 May, 1967, No. 24942/67. Heading H4D. For enhancing seismic reflexion signals an output signal is not produced when two or more seismic signals are of unlike polarity. Signals 1 to 7 from a recording which has been corrected for static and dynamic errors are connected as shown to isolation amplifiers feeding into resistor networks, e.g. R 1 , R 2 , R 3 to afford signals A, B, C, I), E; signals A, B, C, D are combined at point H and signals B, C, D, E at the common point of resistors 61 ... 64. The outputs of switches 123, 136 are fed to a recorder 130. If all resistors in a set are equal, a " tapered mix " ensues but a uniformly weighted " mix " may be arranged. Points A ... E are connected to respective amplifierclippers 72 ... 76 which feed into coincidence circuits 91, 92, 102, 103; for example if circuits 72... 76 all give positive outputs, circuit 91 produces an output and similarly for circuit 102; circuits 92, 103 give an output signal if all their inputs are negative. Outputs, via OR circuits 114, 131 actuate respective switch drivers 118, 134. The coincidence and OR circuits consist of appropriately-poled diodes, a switch driver is a two-triode monostable trigger circuit, and a switch is a diode bridge, Fig. 2 (not shown). An amplifier-clipper may comprise a D.C. amplifier connected at its output to the mid-point of a voltage divider the ends of which are connected to the D.C. amplifier input via oppositely-poled diodes, Fig. 3 (not shown). Alternative apparatus utilizes a digital computer, the input waveforms being quantized into digital representations, Fig. 4 (not shown). Waveform illustrations of the processing are given, Figs. 5, 6, 7 (none shown).
