DLIS or Digital Log Interchange Standard format files are primarily associated with the Oil and Gas industry. These files, containing well-log data, are created following the digital specifications provided by Energistics, a non-profit organization delivering globally applicable, continuously developed, digital-technology standards for the Oil and Gas industry.

Interpreting DLIS Files

DLIS files store data collected from logging tools, instruments used to measure and record physical properties within boreholes during drilling. These datasets are critical in aiding decisions on drilling trajectory and location, as well as in hydrocarbon discovery and recovery. Various types of software can be used to open and interact with DLIS files.

Commercial Software

Commercial software such as Schlumberger's Techlog, Halliburton's DecisionSpace, and Baker Hughes' JewelSuite offer comprehensive tools for opening and interpreting DLIS files. These tools are usually equipped with high performance data processing abilities and advanced visualization features, enabling users to analyze complex wellbore data efficiently. For more information about these software, visit their respective websites here, here, and here.

Open-Source Tools

As an alternative to the commercial software, several open-source tools are available for opening and interpreting DLIS files. Among the most popular is the DLISIO library, a Python package developed for parsing DLIS files. This allows users to read and interpret the data at a programmatic level. More details on this package can be found at this GitHub link.

DLIS File Creation

DLIS files are created by downhole logging tools used in the oil and gas industry. The raw data, collected during drilling, is encoded into DLIS format and stored on the logging equipment. After extraction, the DLIS file is typically passed onto geologists or other professionals for further analysis. To learn more about logging tools, click here.

DLIS File Important Information

Understanding DLIS files is crucial for professionals in the oil and gas industry. Not only do they provide invaluable data for drilling operations, but their platform-neutral format ensures that they can be read and interpreted by a variety of software and tools. However, professionals should be aware of potential compatibility issues between different versions of the DLIS format and ensure the chosen software supports the specific DLIS file version.
