What is a WIS file?

WIS files mostly belong to WellCAD. WIS files are well logging data files used in the oil and gas industry. They store measurements and log information recorded during drilling and well evaluation.
These files come from the Well Information System (WIS) and are used to capture geophysical and petrophysical data that help in analyzing subsurface conditions.
Key details sourced by FilExt.com include:

Data Storage: They keep detailed records of well measurements.

Usage: They assist in evaluating geological formations and well performance.

They are best opened with specialized software such as WellCAD, which is designed to process these industrial data formats.

FilExt.com tip: Additional information shows that these files are essential for professionals performing subsurface analysis and drilling evaluations.

How to open a WIS file

You need a suitable software like WellCAD to open a WIS file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your WIS file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a WIS file directly in the browser:.

WIS file format details:

If you can determine the file format, the associated program can also be determined. The initial characters of a file are called signature, sometimes also referred to as "magic bytes". The signature can be used to infer the file format. Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. If there are problems opening a file, you must first determine the file format used. Our analysis of the WIS files produces the following result:

WIS is seldom used as a file extension and covers different formats for different programs. But the following two file formats are common:

• 25% of all WIS files start with the bytes WIS, which are crucial for this file format. They consist of unreadable binary data. The average file size is 5 MB with most files being between 610 KB and 17 MB in size. The keywords WIS 1.0, LONG_CONST and FLOAT_CONST are typical for these files.
• 2% of all WIS files are associated with WarpIN Script files, which internally utilize the well-known XML format. The Extensible Markup Language (XML) is a simple text-based format for representing structured information: documents, webpages, data, configuration, books, transactions, invoices, and much more. XML defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. The content consists of readable text data, which can be read using a text editor. Most of these files are 2.8 KB to 410 KB in size.

All other WIS files (73%) have different formats. Sometimes used for session, blag, conf, pentana, green or gvax. Just click the "Choose your .wis file to analyze" button on this page to find out what your WIS file is.
