Customer Challenge
Embarked in an exploration and appraisal on its asset, a client identified that a number of legacy neighbor wells and well tests were only available in PDF format and could not be leveraged for regional mapping purposes.
As far as DST data was concerned, over 490 pages, 22,000 rows and 90,000+ entries had to be digitized in tabulated format. On the petrophysics side, over 1.8M of data points had to reproduced, the equivalent of 900,000 curve-feet or about 300 curves over a 1,000m interval
Solution
For this purpose, Vulcania Energy partnered with dedicated team overseas specialized in swift virtualization of legacy documents. Leveraging the latest version of NeuraLog, the team was able to handle a variety of logging measurements such as conventional quad-combo logs, but also lithology tracks, resistivities in logarithmic scale, high-resolution data such as micro-laterolog…
Well header information was captured while splicing of curves was carried out to create composite logs. Finally, a data quality audit was conducted to ensure that the data is fit for purpose for subsequent formation evaluation
Outcome & Value Delivery
All petrophysical logs and well test outputs were delivered in XLS and LAS files in less than 1 week. The format, header and curves were compliant with industry-standard petro-technical software packages such as Kappa Saphire, Techlog or Interactive Petrophysics and could then be subsequently used for prospect analysis
Overall, the preserved value of such data for offshore wells may be estimated to a few million dollars for the two logging programs and up to 10M$ for the digitized well tests.
