Field notes on well log data
Deep technical writing on LAS and DLIS files, mnemonic standardization, formation evaluation workflows, and the unglamorous plumbing behind every reliable petrophysics pipeline.
The Complete Guide to LAS File Format: Structure, Versions, and Common Pitfalls
Everything you need to know about LAS files: how the format is structured, how the three versions differ, where real files deviate from the spec, and what to do about it.
Why Your LAS Files Have 50 Names for Gamma Ray (And What To Do About It)
The single most persistent data management problem in petrophysics — and why semantic matching beats string matching and hand-curated alias tables.
LAS vs DLIS: When to Use Each Format and How to Convert Between Them
Two formats dominate well log data storage. Understanding when each is the right choice — and how to move data between them without losing information — is essential for managing well log data at scale.
