LYNX
has acquired significant technical skill in the art of converting
paper seismic sections and maps to digital formats. This service
is required by researchers and explorationists who own paper copies
of their data but do not have electronic versions available.
Our services
are frequently required due to problems with the original tapes
(formatting errors, stiction, brittle tapes, incomplete tapes),
and due to problems with poor archival procedures (tapes are often
mislabeled, misplaced, or sent out-of-house and never accounted
for). In most of these cases, the company has paper copies archived
and available, but no field or stacked tapes. Occasionally, field
tapes can be found but it may be less expensive and more expedient
to simply digitize the paper copies, rather than attempt to read
and process vintage tapes.
In some cases,
our clients have received paper sections of seismic lines shot in
remote, immature basins. Resource departments in these developing
nations may wish to expand foreign participation in bidding competitions
and may give paper seismic sections to explorationists. LYNX can
facilitate the analysis of the data by quickly reconstructing digital
data from the paper sections, turning paper copies into SEG-Y format
data that can be filtered, migrated, loaded to workstations, and
tied to other data.
The seismic
paper sections are processed through LYNX proprietary algorithms
which have been developed and improved over the past seven years,
following the work procedure summarized below:
- The paper
sections are scanned at high resolution;
- Sophisticated
pattern recognition software is used to reconstruct individual
traces;
- A quality
check plot is made at the same scale as the original section;
- Traces are
output in SEG-Y format with available survey locations included
in the headers;
- The final
product is delivered on the client's chosen medium, ready for
deconvolution, migration, or other processing routines, and is
workstation-ready.
