Borehole Log Columns

Borehole data in a log is presented in form of Log Columns.

RSLog provides access to different types of log columns that could be used in your borehole log templates.

Structure of Log Columns

The lower portion of the page on log template design page presents a list of log columns used in a log template. The height of the column-header may be specified using the textbox on the right side of the table (see below):

As you make changes in the list of log columns the program calculates the 'blank space' on the log, based on the paper size and total of all column widths. This is shown in an orange or blue badge at the top-right corner of the table showing the list of log columns.

In order to change the order of the log columns in the list, click on the hamburger icon and hold, then move the selected row to the desired position and drop it there.

List of Log Columns

The log columns may be added / deleted / edited using the toolbar at the top of the table. Each row in the table represents one log column. The order of log columns (rows in the table) determines the order they appear in the borehole log: the first log column in the table will be the first column on the left, then the second columns and so on.

Types of Log Columns

The log columns are categorized into two groups—Text/Number or Graphical—depending on the way you want to present data in the borehole log.

For all log columns user can define the following properties:

Column-Header Text - this is the title of the column as shown on the borehole log.
Column Width - this is the size of log column (mm or inch).
Additional Settings - depending on the type of log column selected, additional settings may be available (see below).

Text/Number Log Columns

These log columns show either a number (e.g. blow counts, moisture content, etc.) or a text (e.g. lithologic description, depth related remarks, etc.). These types of columns are further broken down into two categories:

1. General tab

The log columns available in this category include:

Comment / Additional Notes - displays comments or remarks at specific depths in the borehole log (e.g., drilling notes, seepage, change in the drill method or casing size etc.). The source of this column is the data entered in the Comments tab of test hole edit page.
Discontinuities - displays the discontinuities data in the borehole log as a table. This is the data entered in the Discontinuities tab of the test hole edit page.
- Select Sub-Columns: User can select which sub-columns should be included in log. Please note a minimum 5 mm width is required for each sub-column.
Drill Run Info - displays the data entered for each drill run in the borehole log as a table. This is the data entered in the Drill Runs tab of the test hole edit page.

Select Sub-Columns: User can select which sub-columns should be included in log. Please note a minimum 5 mm width is required for each sub-column.

Lithologic Description - displays the data entered for soil/rock layers in the Stratigraphy tab of the test hole edit page.
- Show Depth & Elevation of the Layers: if selected, the depth and elevation of bottom of each layer will be shown in the log column (see below). You can also define whether these numbers should be presented As Entered (i.e. in project unit system), Always in Feet, or Always in Metres.

Log Columns: Showing Depth & Elevation for Each Layer

Layer Elevation / Depth Bar - displays a column with the elevation and depth of top of each layer.
Method of Investigation - displays two sub-columns in the log: Method of Investigation (e.g. auger drilling, etc.), and Drill Rig. The source of this column in the data entered in the Boring Details tab of test hole edit page.
Samples - displays sample information as a column in the log. The source of this column in the data entered in the Samples tab of test hole edit page.
- Show Sample Number: if selected the sample number will be shown as a sub-column.
- Show Moisture Level: if selected, sample moisture conditions will be shown in a sub-column (e.g. D for Dry, DM for Dry to Moist, etc.).
- Show Sample Type: if selected, the sample type sub-column will be shown next to the sample number. User can select to show Symbols (e.g. AS, CC, etc defined on the Settings page) or Icons according to the list of sample types defined in their account settings.

2. Test Results tab

The log columns available in this category include:

Atterberg Limits - displays the results of Atterberg Limits test, as entered in Lab. Tests page.
- Show PI Instead of PL: by default, the Atterberg Limits column shows Liquid Limit (LL) and Plastic Limit (PL) in the log. User can select to show Plasticity Index (PI) instead of PL.
Field Test Results - displays the results of a field test (e.g. SPT, Hydrocarbon, etc) at each depth, as entered in the Field Tests tab of the test hole edit page.
- Select Field Test: click on the dropdown to select the field test for which the results are presented in the log.
Gradation Test - displays the results of gradation test as percent clay, silt, sand and gravel, as entered in Lab. Tests page. This columns displays three sub-columns: Fines (%), Sand (%), and Gravel (%).
Lab. Test Results - displays the results of a lab test carried out on samples, as entered in Lab Tests page.
- Select Test Category: refers to the data entry tabs on the Lab. Tests page.
- Select Lab. Test: depending on the selected Test Category, user should select the lab. test for which the results will be shown in the log.
Summary List of Lab Tests - displays a list of lab. tests carried out on a specific sample (includes acronym of lab. tests, not the test results).

Graphical Log Columns

These log columns show either a graph or some sort of drawing, and are further broken down into these two categories:

1. Basic tab

Depth Scale - shows a depth scale in the log. User can select to show metres and/or feet on the depth scale.
- Feet: if selected, the depth scale will be shown in feet (left half of the scale).
- Metres: if selected, the depth scale will be shown in metres (right half of the scale).
- Show Water Level Symbol: if selected, groundwater level symbol (hollow triangle) will be shown on the depth scale column. The source of this water level is General tab of test hole edit page.
Drill Run - displays the results of TCR, RMR, etc as a stepped graph in the borehole log. The source of this column in the data entered in the Drill Runs tab of test hole edit page.

Select Sub-Columns: for each sub-column selected, you can specify the color and direction of the plot: → means the horizontal axis increases to the right; and ← means the horizontal axis increases to the left.

Lithological Symbol (hatch pattern) - displays the hatch pattern (legend) of a stratum. This is based on the hatch patterns selected in Stratigraphy tab of test hole edit page.
- Hatch Options: during defining a stratum, hatch pattern may be selected from the main categories: USCS (Unified Soil Classification System), AASHTO (American Association of State Highway and Transportation Officials), AGS (Association of Geotechnical & Geoenvironmental Specialists - UK), Rock, and Miscellaneous.
- Color Settings: user can select both foreground and background color of each hatch on the account settings page.
Piezometer / Well - displays the details of piezometer/well construction for a test hole entered in the Instrumentation > Piezometer / Well tab of test hole edit page.
- Include Water Level Measurements: if selected, groundwater level measurements entered in Groundwater Monitoring section of the Piezometer / Well tab will be displayed in the log.
