The GEO Software Suite

[edit] 1. Overview

GEO is a software technology in widespread use within the international oil industry.

The GEO Software is comprised of an integrated group of 32-bit PC-based applications, designed for the wellsite geologist and operations geologist.

GEO software became popular because it was easy to learn and intuitive for a geoscientist to use. At the heart of the GEO system lies a unique document file format, the ODF [*.odf], which allows for all the data and associated curve and lithology information, documents, maps, diagrams, tables, etc., for any well to be embedded or dynamically-linked as an archive, within a single file.

Its in-built compression technologies are such that an ODF can contain a great wealth and range of data values and types, without the file size increasing to unmanageable proportions.

This makes the ODF document file a useful means of transporting, sharing and storing well information and lends itself to being transferred as a small e-mail attachment.

The well information within an ODF file is always presented in the form of a user-selectable well log format. However, unlike the TIFF or PDF static formats commonly used for sharing log information, the ODF is a dynamic means of containing well information.

On opening a received ODF file, the user may choose to view or interact with the information it contains in a number of alternative log layouts; the one file can contain a wellsite lithology log, mudlog, draft composite log, core log, wireline log or progress log, etc., all selectable from a drop list.

Similarly, the user can toggle depth units between feet and metres, select a different scale, or even an alternative depth reference (e.g. Measured Depth, True Vertical Depth/True Vertical Depth Sub-Sea, or Two Way Time).

The GEO authoring applications are equipped with talented templates, which automate most of the data input and display.

As the geologist loads data and builds the wellsite lithology log, all other log layouts are filled in the background, including any which might contain analytical cross-plots or quick-look petrophysical analyses.

All data within any ODF is also always accessible (dependent on individual user permissions) for viewing, editing, or exporting to other applications, or to a corporate database.

As a member of POSC (now Energistics), Geologix helped shape the WITSML standard for log data sharing.
