Abstract

Vast quantities of seismic data are collected over the life cycle of an E&P company from scouting, through Exploration, Development and Production. Conventionally this data is stored and maintained on 3590 tapes which grow in to large numbers (>100,000) in line with size and age of company. With 8-10 year shelf life, these large tape- libraries need expensive facilities and operational maintenance. Need for Transcription is due to factors like Growth and Space Requirement, Media Deterioration, Managing End of Life Technologies, Business Continuity and Disaster Recovery. This work has developed a Standard Operating Procedure for Transcription QC, which is not available in the industry. The paper presents the SOP developed and tested for a large and comprehensive transcription project of an entire seismic repository. This methodology is proposed to be considered for adoption as a reference framework for standardization of seismic Transcription QC at E&P companies.
