  • Whether you are an experienced computer user or not, you can quickly learn to use StripLog.
  • If you are familiar with similar Windows programs, you will be off and running in minutes.

Saves Log Creation and Data Input Time

  • Rapidly create well logs that are rich in data, including: ROP and Gas data, lithology and other symbols, engineering and geological descriptions, surveys, porosities, and grain sizes.
  • Automatically import ROP, Gas and other data from gas detectors and EDR systems.

High-Quality Output

  • Clear, precise, professional quality printed strip logs.
  • Built-in header information for the well, the operator, the geologist, cores, DSTs, plan, elevation, etc. Plus custom header sections with your logo and other images.
  • Support for continuous feed printers. (Plotter support is available in LogManager.)
  • Import and export data to/from the log in a variety of formats.

StripLog 8 Features

Easy User Interface

  • Work directly on the strip log as it will appear when printed.
  • Efficient point, click and drag interface.
  • Change the depth range at any point during the project.
  • Change the log scale or convert to TVD-indexed log.
  • Scroll to any depth or go directly to a specific depth.
  • Zoom in or out to see more detail or more of your log.

Log Types

  • Use either feet or meters for depth.
  • Several depth scales for well logs and core logs.
  • Measured Depth logs can be converted to True Vertical Depth.

ROP, Gas, Gamma, and Other Data

  • Two or more data curve tracks can display up to 10 data curves each.
  • Each curve’s name and unit can be customized. For example, you could have ROP (min/ft), Gas (%), and Gamma (API).
  • Each curve can be logged at its own data step. For example, ROP and Gas could be logged at 1 M steps, and Gamma could be logged at fifths of meters.
  • Import curve data instantly from gas loggers or other sources in LAS 2 or LAS 3 (Log ASCII Standard) or delimited ASCII files.
  • Enter or correct curve data directly, including Power Entry features like Shift, Add, Multiply, and Interpolate. Data values are plotted as you modify them.
  • Live Data Acquisition (LDA) imports ROP, Gas, and other curve data automatically at regular time intervals from gas detectors or EDR systems.
  • Customize each curve’s appearance: color, line style, width, filled wrapped areas, etc.
  • Change data scales as needed at any depth.

Lithology, Mineral, Fossil, and Other Symbols

  • Add and move symbols with a click of the mouse.
  • Pre-loaded with a complete set of industry standard symbols, including: major rock types, fossils, minerals, stringers, textures, porosity types, sorting, rounding, oil shows, cores, & DSTs.
  • Both percent lithology and interpreted lithology tracks.
  • Where the supplied symbols do not meet your requirements, you can design and add new symbols.

Geological Descriptions and Engineering Data

  • Import or export all geological descriptions in one step – abbreviating or expanding terms automatically.
  • Geological descriptions and engineering data can be added and moved to any depth – just double-click where you want the text and start typing.
  • Assisted Description Mode helps you to enter descriptions quickly and flexibly based on lithology intervals.
  • Use cut, copy, and paste to quickly copy text to or from your word processor.
  • Choose from font sizes 7 to 20.

Porosity and Grain Size

  • Set the porosity or grain sizes for one depth or a range of depths with one click and drag of the mouse.
  • Set individual grain sizes independently.


  • Built-in Headers include: Well Info, Core, Operator, Comments, DSTs, and Symbol Legends.
  • Custom Headers can be added: Plan, Elevation, Symbol Legend, and completely Customized Headers with any text and graphic arrangement.


  • Survey data can be plotted as a graph: Vertical Section, TVD, etc.
  • Survey text can be automatically positioned at the wellbore or at the track edge.
  • Survey data can be used to convert MD logs to TVD logs

Import Data

  • ROP, Gas, or any other curve data in LAS or ASCII
  • Surveys
  • Geological Descriptions

Export Data

  • ROP, Gas, or any other curve data as LAS or ASCII
  • Combined LAS format integrates lithology and curve data
  • Surveys
  • Geological Descriptions
  • Log image in JPEG or TIFF format
  • PPDM
  • All Data


Any of the following log characteristics can be customized:

  • Depth Range
  • Depth Scale
  • Tracks in the log Layout
  • Data Layers in each Track
  • Data Curves: color, width, pattern, scale, linear vs. semi-logarithmic, data step
  • Survey graphs (e.g. Vertical Section) and Survey Text
  • Symbols and Symbol Libraries
  • Headers and Legends

All customizations can be saved in Template files that can be used to quickly create new logs with the required format.

Quick Information Bar (Status Bar)

  • Continuously displays the depth and the name of the track under the mouse cursor.
  • Displays the current font size or symbol type for that track.
  • Prompts remind you how to use each track.


  • Use any page-oriented raster printer with continuous print capability.
  • Print any depth range of the log, and optionally include log headers, symbol legends, and track headings.
  • Logs can be printed at various standard scales. For example:
    • Well logs: 1:240, 1:480, 1:600, 1:1200, 1:200, 1:500, 1:1000 up to 1:12,000
    • Core logs: 1:20, 1:48, 1:50
