The Service
What is well log certification?
Well log certification is the technical process of recovering, digitizing and validating historical well logs so they meet modern oil industry standards. Through rasterization and vectorization of the original documents, we transform curves on paper, film or microfilm into precise, editable digital data.
A certified log guarantees that the subsurface information is faithful to the original record, free of digitization errors, and can be used with confidence in petrophysical evaluations, geological models and investment decisions.
The Process
From physical document to certified data
Rasterization
High-resolution digitization of logs on paper, film or microfilm, preserving every detail of the original document.
Vectorization
Conversion of raster curves into editable numeric data, with depth, scale and nomenclature control.
QA/QC Validation
Verification of every curve against petrophysical acceptance criteria and against the original document.
Certification
Issuance of the certified log in LAS format, with a technical report documenting the process and guaranteeing data traceability.
Why it matters
Investment decisions backed by reliable data
Auditable data
Every certified log is traceable back to its original source and can be defended before partners, auditors and investors.
Savings vs. new acquisition
Certifying existing logs costs a fraction of the price of drilling or re-logging a well.
Industry standard
Logs are delivered in LAS format, compatible with all modern petrophysical and modeling software.
Preserved technical heritage
We recover decades of subsurface information that would otherwise be lost to paper deterioration.
Frequently Asked Questions
Frequently asked questions about well log certification
What is the difference between rasterization and vectorization?
Rasterization digitizes the document as a high-resolution image; vectorization converts those images into editable numeric data curves that can be exported to LAS format.
Which logs can be certified?
We certify well logs from any era, including logs on paper, film or microfilm from the 1920s to the 1980s, as well as low-quality previous digitizations.
In what format are certified logs delivered?
Logs are delivered in the industry-standard LAS format, accompanied by the digital images and a technical certification report.
How much does certifying a log cost compared to acquiring new data?
Certifying existing logs costs a fraction of the price of drilling or re-logging a well, recovering information that would otherwise be lost.
