Seismic Data Tape Transcription

One of the biggest data management challenges facing oil and gas companies today is the vast amount of different media technologies and seismic data formats used throughout the history of seismic exploration. Seismic data is extremely valuable and rarely ever destroyed. To make this information useable in today’s environment, you will need to transform this data into a new media format or disk for reprocessing or interpretation.

GTI has the largest capacity and capability to read and recover data from any magnetic media or disk ever used throughout the industry’s history of recording seismic data. From original analog tapes to new 3592 technology, GTI is the only company that can handle all your data requirements, no matter the recording technology. Our tape conversion services include:

  • Bit-for-bit tape copies
  • Demultiplexing
  • Reformatting
  • Navigation merges
  • No permit exclusions
  • Complex data extractions or cut-outs

GTI offers a complete set of services from bit-for-bit copy, reformatting and demultiplexing of old legacy formats, to standard SEGY. Our advanced quality control tools ensure the trace data is converted properly and all header information fully populated.

Legacy Media Issues

GTI has specialized equipment and personnel which permit us to handle the following types of problems frequently encountered with legacy media:

  • Stiction (media binder deterioration)
  • Wide, narrow or damaged tapes
  • Amplitude recorded outside drive ANSI specifications
  • Density recorded outside ANSI specifications
  • Parity errors
  • Tape skew

Physical damage to tapes is a problem that we deal with on a regular basis. In some cases, the damaged sections of a tape must be removed before splicing back the undamaged sections of tape.
