Organising seismic data since the early 90s - over 300,000 tapes.
Our work started with the concept of a single database, a national repository based on PetroBank, sharing data management costs and making data easily available to industry. The Banco de Dados E&P (BDEP) has been on-line since April 2000.
DPTS has loaded well logs, post-stack seismics, and about 60% of the pre-stack seismic available in Brazil. Loading pre-stack data into PetroBank requires accurate metadata linking files, geometry and shotpoint coordinates. Obtaining this information requires a lot of effort, but it's the only way to get high quality, useable data, and to have enough confidence in the transcription process to be able to destroy the originals.
The 300,000 tapes remastered to date have been selected following the analysis of some 350,000 tapes (10% were duplicates and were discarded, and 4% missing something - coordinates, obs logs). Remastering is a complex process, and this work shows how it can add significant value to the seismic archive.
