Abstract

There are ten 408UL Telemetry Data Acquisition Systems working in three sectors of ONGC for acquiring high-resolution seismic data. These systems supplied by Sercel, France record data on NAS (Network Attached Storage) in SEGD-8058 32- bit IEEE format. SQC-Pro displays the Data on LCD Monitor with selected Processing parameters for real-time QC. Due to limited available time for Acquisition a detailed QC Analysis cannot be under-taken in the Instrument Cabin. FPU (Field Processing Unit) facilitates Processing of Data after it is read using a SCSI Drive. Hence, it is mandatory to write Data on Cartridge before it can be processed. Air-conditioned dust free environment with high power UPS should be provided for the FPU and SCSI Drive. The services of well trained/experienced Geophysicist needed for effective use of FPU. If detailed Analysis and basic QC of Data can be done for the SEGD Disk Files using the most commonly available Windows PC, the field crew would certainly benefit from it. Keeping this in view a set of Software Utilities have been developed for which no specialized training or expertise required.
