Tape Transcription

Tape Transcription

Operating since 1984, CGG provides specialist data recovery, seismic reformatting, archival and data management solutions to the oil and gas industry. The scope of work varies from small single tape copy jobs through to large archiving projects involving data recovery and reformatting of hundreds of thousands of legacy tapes. As a leading geoscience company, CGG not only delivers these services but our people understand the data, and the value of the data within the E&P process. With tape transcription facilities located across the world CGG is one of the largest providers of services dedicated to the Oil & Gas industry.

Reformatting Legacy Data

Our application of appropriate data recovery techniques is essential to minimize irretrievable data loss. The correct format recognition and application of appropriate reformatting software and parameters is required to maintain data integrity.

  • Reporting and Metadata Management

Data Recovery

All magnetic media are subject to deterioration of the magnetic coating. CGG has the expertise, tools and techniques to maximize the data that can be recovered from such damaged or deteriorating tape media. The oxide layer of deteriorating tapes can be irretrievably destroyed through attempts to read the data without applying appropriate treatment or techniques.

Duplicating and Copying

Our capabilities include all common media types used within the oil & gas industry, past and present. Utilizing a “format-aware” copy process where applicable, this not only copies the data but also provides listings and will highlight/correct format anomalies. Data can be duplicated to a range of media types.

3590 Audits

CGG will assess how safe your data is in your existing 3590 library. We can allocate a member of our staff to work on-site at any facility required. Our on-site data archiving is ideal for valuable, sensitive data that needs to be revised and maintained. Our transportable hardware and software can be used worldwide.
