Method and apparatus for compiling, compositing, correlating and normalizing seismographic data

Claim 1

A DEVICE FOR CORRELATING A FIRST SIGNAL HAVING AN UNKNOWN FREQUENCY CONTENT WITH A SECOND SIGNAL HAVING A PREDETERMINED FREQUENCY CONTENT, THE FIRST SIGNAL BEING RECORDED ON A RECORD SHEET ADAPTED TO BE ATTACHED TO A DRUM, THE DEVICE COMPRISING: A SUPPORT FRAME; A DRIVE SHAFT JOURNALED ON THE SUPPORT FRAME; DRIVE MEANS OPERATIVELY CONNECTED TO THE DRIVE SHAFT FOR DRIVING THE DRIVE SHAFT; FIRST DRUM MEANS CONNECTED TO THE DRIVE SHAFT FOR RECEIVING THE RECORD SHEET UPON WHICH THE FIRST SIGNAL IS RECORDED; SECOND DRUM MEANS CONNECTED TO THE DRIVE SHAFT AND HAVING A SURFACE UPON WHICH A SIGNAL CAN BE RECORDED AND HAVING A DIAMETER SUBSTANTIALLY GREATER THAN THE DIAMETER OF THE FIRST DRUM MEANS FOR INCREASING THE RESOLUTION OF THE CORRELATION SIGNAL; THIRD DRUM MEANS CONNECTED TO THE DRIVE SHAFT AND HAVING A SURFACE UPON WHICH A SIGNAL CAN BE RECORDED; FIRST ELECTRICAL MEANS HAVING A REPRODUCING HEAD OPERATIVELY POSITIONED ADJACENT THE FIRST DRUM MEANS AND A RECORDING HEAD OPERATIVELY POSITIONED ADJACENT THE SECOND DRUM MEANS FOR REPRODUCING THE SIGNAL FROM A RECORD SHEET ATTACHED TO THE FIRST DRUM MEANS AND MAGNETICALLY RECORDING THE SIGNAL ON THE SURFACE OF THE SECOND DRUM MEANS; CORRELATION HEAD MEANS CONSISTING OF AN ELONGATED CONDUCTOR MEANS HAVING A CONFIGURATION APPROXIMATING THE WAVE SHAPE OF SAID SECOND SIGNAL, SAID HEAD MEANS BEING OPERATIVELY POSITIONED ADJACENT TO THE SURFACE OF THE SECOND DRUM MEANS FOR PRODUCING A CORRELATION SIGNAL FROM THE SIGNAL RECORDED ON THE SURFACE OF THE SECOND DRUM MEANS; AND, SECOND ELECTRICAL MEANS OPERATIVELY CONNECTED TO THE CORRELATION HEAD MEANS AND HAVING A RECORDING HEAD OPERATIVELY POSITIONED ADJACENT TO THE THIRD DRUM MEANS FOR RECORDING THE CORRELATION SIGNAL ON THE THIRD DRUM.

Claim 2

A DEVICE FOR CORRELATING A FIRST SIGNAL HAVING AN UNKNOWN FREQUENCY CONTENT WITH A SECOND SIGNAL HAVING A PREDETERMINED FREQUENCY CONTENT, THE FIRST SIGNAL BEING RECORDED ON A RECORD SHEET ADAPTED TO BE ATTACHED TO A DRUM, THE DEVICE COMPRISING: A SUPPORT FRAME; A DRIVE SHAFT JOURNALED ON THE SUPPORT FRAME; DRIVE MEANS OPERATIVELY CONNECTED TO THE DRIVE SHAFT FOR DRIVING THE DRIVE SHAFT; FIRST DRUM MEANS CONNECTED TO THE DRIVE SHAFT FOR RECEIVING THE RECORD SHEET UPON WHICH THE FIRST SIGNAL IS RECORDED; SECOND DRUM MEANS CONNECTED TO THE DRIVE SHAFT AND HAVING A SURFACE UPON WHICH A SIGNAL CAN BE RECORDED AND HAVING A DIAMETER SUBSTANTIALLY GREATER THAN THE DIAMETER OF THE FIRST DRUM MEANS FOR INCREASING THE RESOLUTION OF THE CORRELATION SIGNAL; THIRD DRUM MEANS CONNECTED TO THE DRIVE SHAFT AND HAVING A SURFACE UPON WHICH A SIGNAL CAN BE RECORDED; FIRST ELECTRICAL MEANS HAVING A REPRODUCING HEAD OPERATIVELY POSITIONED ADJACENT THE FIRST DRUM MEANS AND A RECORDING HEAD OPERATIVELY POSITIONED ADJACENT THE SECOND DRUM MEANS FOR REPRODUCING THE SIGNAL FROM A RECORD SHEET ATTACHED TO THE FIRST DRUM MEANS AND MAGNETICALLY RECORDING THE SIGNAL ON THE SURFACE OF THE SECOND DRUM MEANS; CORRELATION HEAD MEANS CONSISTING OF AN ELONGATED CONDUCTOR MEANS HAVING A CONFIGURATION APPROXIMATING THE WAVE SHAPE OF SAID SECOND SIGNAL, SAID HEAD MEANS BEING OPERATIVELY POSITIONED ADJACENT TO THE SURFACE OF THE SECOND DRUM MEANS FOR PRODUCING A CORRELATION SIGNAL FROM THE SIGNAL RECORDED ON THE SURFACE OF THE SECOND DRUM MEANS; AND, SECOND ELECTRICAL MEANS OPERATIVELY CONNECTED TO THE CORRELATION HEAD MEANS AND HAVING A RECORDING HEAD OPERATIVELY POSITIONED ADJACENT TO THE THIRD DRUM MEANS FOR RECORDING THE CORRELATION SIGNAL ON THE THIRD DRUM.

Claim 3

A METHOD FOR COMPILING AND PROCESSING SEISMIC DATA COMPRISING THE STEPS OF: RECORDING A REFERENCE SIGNAL ON A FIRST RECORD SHEET; REPRODUCING THE REFERENCE SIGNAL AND SIMULTANEOUSLY INDUCING A SEISMIC SIGNAL IN THE EARTH CORRESPONDING TO THE REFERENCE SIGNAL, DETECTING THE SEISMIC REFLECTION SIGNAL FROM THE INDUCED SEISMIC SIGNAL AND SIMULTANEOUSLY RECORDING THE SEISMIC REFLECTION SIGNAL ON THE FIRST RECORD SHEET; MOVING THE FIRST RECORD SHEET IN SYNCHRONISM WITH SECOND AND THIRD RECORD SHEETS WHILE MAINTAINING THE RECORD SHEETS IN A PREDETERMINED RELATIVE RELATIONSHIP; REPRODUCING THE SEISMIC REFLECTION SIGNAL FROM THE FIRST RECORD SHEET, RECORDING THE SEISMIC REFLECTION SIGNAL RECORDED ON THE SECOND RECORD SHEET, CORRELATING THE SEISMIC REFLECTION SIGNAL RECORDED ON THE SECOND RECORD SHEET BY A FIRST CORRELATION HEAD TO PRODUCE A CORRELATION SIGNAL; RECORDING THE CORRELATION SIGNAL ON THE THIRD RECORD SHEET; AND, REPRODUCING THE REFERENCE SIGNAL FROM THE FIRST RECORD SHEET AND RECORDING THE REFERENCE SIGNAL ON THE SECOND RECORD SHEET, CORRELATING THE REFERENCE SIGNAL RECORDED ON THE SECOND DRUM TO PRODUCE A ZERO TIME CORRELATION SIGNAL AND RECORDING THE ZERO TIME CORRELATION SIGNAL ON THE THIRD RECORD SHEET.

Claim 4

A METHOD FOR COMPILING AND PROCESSING SEISMIC DATA COMPRISING THE STEPS OF: RECORDING A REFERENCE SIGNAL ON A FIRST RECORD SHEET; REPRODUCING THE REFERENCE SIGNAL AND SIMULTANEOUSLY INDUCING A SEISMIC SIGNAL IN THE EARTH CORRESPONDING TO THE REFERENCE SIGNAL, DETECTING THE SEISMIC REFLECTION SIGNAL FROM THE INDUCED SEISMIC SIGNAL AND SIMULTANEOUSLY RECORDING THE SEISMIC REFLECTION SIGNAL ON THE FIRST RECORD SHEET; MOVING THE FIRST RECORD SHEET IN SYNCHRONISM WITH SECOND AND THIRD RECORD SHEETS WHILE MAINTAINING THE RECORD SHEETS IN A PREDETERMINED RELATIVE RELATIONSHIP; REPRODUCING THE SEISMIC REFLECTION SIGNAL FROM THE FIRST RECORD SHEET, RECORDING THE SEISMIC REFLECTION SIGNAL RECORDED ON THE SECOND RECORD SHEET, CORRELATING THE SEISMIC REFLECTION SIGNAL RECORDED ON THE SECOND RECORD SHEET BY A FIRST CORRELATION HEAD TO PRODUCE A CORRELATION SIGNAL; RECORDING THE CORRELATION SIGNAL ON THE THIRD RECORD SHEET; AND, REPRODUCING THE REFERENCE SIGNAL FROM THE FIRST RECORD SHEET AND RECORDING THE REFERENCE SIGNAL ON THE SECOND RECORD SHEET, CORRELATING THE REFERENCE SIGNAL RECORDED ON THE SECOND DRUM TO PRODUCE A ZERO TIME CORRELATION SIGNAL AND RECORDING THE ZERO TIME CORRELATION SIGNAL ON THE THIRD RECORD SHEET.
