Applecore 10.1

Advanced borehole logging package for Windows (and the Mac)

  • Overview

    AppleCORE is an advanced borehole log production application for Windows and Mac systems. As of 1st January 2017 GeoMEM are supplying the Windows version only.

    AppleCORE is developed and maintained by Dr. Mike Ranger of Alberta, Canada and has been used by professionals around the world for over 20 years.


    AppleCORE is designed by a geologist, with the features geologists have asked for.

    AppleCORE is in use worldwide by many of the largest petroleum and service companies because of its unique graphical interface. AppleCORE is easy to learn, fast, and intuitive (even fun) to use. It handles the tedious aspects of litho-logging and lets you concentrate on the rocks. Detail of an AppleCORE graphic litho-log

  • AppleCORE: Main features 1


    AppleCORE's great strength compared to other strip log programs is its data input functions, which are extremely fast, geologically intuitive, and user friendly.

    Data input is a separate function from the strip log drafting. AppleCORE employs a completely graphical method for data input using the mouse, allowing rapid, systematic, and precise data input. It is a true "core logging" program, rather than simply a strip log drafting program.

    Menus provide for over 300 lithologies, all of which can be customised. For example, there are separate customisable palettes for physical structures, lithologic accessories, trace fossils, fossils, pore types, fractures, hydrocarbon indicators as well as many other forms of geological data.

    AppleCORE also includes extensive functions to record hard rock lithology in great detail and has been used by the Ocean Drilling Program as their primary visual core description tool.

    Log creation features

    Patterns, symbols, and captions are all easily modified.

    Up to 16 sets of numerical data such as geophysical logs in .LAS format or laboratory measurements can be imported for plotting as graphs on the strip log.

    Digital images can be imported and annotated for display on the strip log.

    Once the data are collected, the strip log can be drafted to any scale, and in a wide variety of formats, in colour or black and white.

    The lithology column can be formatted to closely mimic a hand-drawn image using grain-size to produce an erosional profile suitable for publication.

    All of the raw data can be exported as a simple ASCII text file, which can be transferred easily to other computer platforms. The text file consists of a list of depth intervals and simple codes to represent the various descriptive data. The codes are all explained in the software documentation that comes with the software.

    The strip log graphic can also be exported in various formats, raster or vector, such as: JPEG; TIFF; BMP; PDF; PostScript etc.

  • AppleCORE: Log creation and display


    AppleCORE uses three main windows for the collection and display of data: the Log Header; the Data Entry and the Strip Log windows. Each of these windows can be accessed from the "Window" item in the menu bar.

    The Log Header window is used to enter descriptive and configuration data about the well or stratigraphic section. This is typically information that you would expect to see on the strip log header. In "Core" configuration there are two buttons in the lower right of this window labelled the Box Tally button and Box Depths button, which are used to record the number of cores and the number of boxes in each core as well as their depths. The Log Header window disappears when not in use.

    The Data Entry window is used to graphically record the descriptive data. It has a number of different "palettes" and therefore it changes its appearance somewhat depending on the type of data that is being recorded. The different data palettes are selected from the "Logging" item in the menu bar. When you choose one of the logging palettes, the Data Entry window will be made the frontmost window if it isn't already. You can change the position of the Data Entry window on the screen but you cannot alter its size.

  • The Strip Log window, is a scrolling window that displays the drafted strip log. No data can be entered from the Strip Log window. The Strip Log window can be resized and its position on the screen may be moved as desired.

    Other selected features

    • Some descriptive items are recorded as "icons" (Physical Structures, Lithologic Accessories, Ichnofossils, Fossils etc.) based on an interval with a relative abundance.
    • Data items that can be recorded include:
      • Diagenesis
      • Fractures
      • Pore Types
      • Hydrocarbon Indicators
      • Lithification descriptors (consolidation & fissility)
      • Rock Colour (descriptive terms based on GSA Rock-Colour Chart)
      • Facies & Interpretive remarks (see right)
      • Clay Percentage
    • Unit divisions on the scale bar next to the core schematic in the Logging window can be customised to the user's preferences.
    • Facies and Interpretive remarks can be recorded under a hierarchy of: Facies; Facies Association; Depositional Environment and Depositional Complex.
      These are plotted on the strip log in vertical columns. Commonly used terms can be stored in a scrolling lists for repeated use. Any of the terms stored in the lists can be assigned a background colour to plot in the strip log columns. This allows dramatic visual emphasis of important facies or facies successions.
    • Comprehensive menus of descriptive "icon" items:
      300 for each of Physical Structures and Fossils
      150 for each of Lithologic accessories and Ichnofossils (all fully customisable)
    • Comprehensive menu of lithologies with 4 "palettes" for each of siliciclastics and carbonates for a total of 128 lithologies (all fully customisable).
    • External numeric data (X-Y data) can be imported for plotting as a curve on the strip log. Such data may be, for instance, gamma ray readings or porosity analysis. Two curves can be plotted in the single track, with several different options including the ability to offset a curve relative to the litho log (as may be require with geophysical logs).
    • Header remarks are unlimited in length.
    • Enhanced strip log format with "aesthetic" division lines and rotated text. Separate column for descriptive "icon" items.
    • AppleCORE is automatically backed up while logging. If the system crashes, extensive loss of data is prevented.
  • AppleCORE User Group on LinkedIn

    There is an AppleCORE User Group on LinkedIn. This has been set up to

    1. Allow technical discussions about AppleCORE amongst users, and
    2. Provide news of updates and new versions as they become available

    Go to the AppleCORE User Group on LinkedIn (opens a new tab or window).
