# Well Log Visualization User Guide

What is a Well Log Visualization? The well log visualization is a detailed two-dimensional record of tracks that can be used in petroleum exploration and production applications to show various physical, chemical, electrical, or other properties of the rock/fluid mixtures versus depth penetrated during drilling. Well-log visualization is important in E&P operations in the areas of analyzing electron density, resistivity, photoelectric effect, neutron absorption rate and other related properties, which in turn are useful in the determination of reservoir volume, hydrocarbon in place, reserves estimation and formation lithology.

# How to create a Well Log Visualization

# To insert a well log visualization

Click on the well log visualization icon on the toolbar or select Visualization > Add visualization... from the menu.

well log icon

# To configure the well log visualization

Click on the properties icon () to open the properties menu
Go to Data and select a data table from the data table drop-down list
Set Limit data using filterings to the appropriate filtering scheme
Set the column properties for the curves under Curve Data
If you have multiple wells, set the Trellis by to the column trellis the view by wells
Set the number of wells to display per page
If you have curve data that has been pivoted, check the box next to My data is pivoted
Set the Depth column,** Curve name column**, and **Curve value column **for the curve data selection
Click (+) to add a track or curve. For help on configuring curves, please see the video on how to create a well log visualization.

# Using the Well Log controls

To use these mouse controls, first hover over the track.

Zoom in	Scroll up
Zoom out	Scroll down
Pan up	Left-click and drag the mouse down
Pan down	Left-click and drag the mouse up

To affect the view of all tracks at the same time, first line up the track scales as closely as possible by using the mouse controls on the individual tracks. Use the controls on the navigation menu.

TIP

To reset the view for all tracks, click the re-center icon in the navigation menu.

Keep in mind this will reset the view for all tracks.

Lastly, you can reorder the layout of the well log visualization by click in the right-hand corner of the track and dragging it into the desired position in the layout.

# How to Reset the Zoom

To reset the zoom:

Click on the zoom reset icon reset in the controls menu to the left of the visualization.

# How to mark data in a track?

To mark data in a track, the marking "area" in the well log visualization is on the leftmost border of the track.

Hover over this area and left-click on the mouse to mark along the points of interest.
Use Ctrl + Left Mouse click to mark multiple points of interest along the same track.

TIP

The mouse cursor should change to a (+) shape when marking is activated.

# What are the Properties of a Well Log Visualization?

There are three (3) property types that can be configured in Well log visualization. These correspond with the classes: curve, formation top, track.

A well log can have multiple tracks and formation tops.
A track can have multiple curves.
A formation top is distributed across all tracks.

# How to configure the Well Log Visualization

To access the Properties menu, click the gear icon on the Well Log visualization.

# General

This general setting is similar to other visualizations inside Spotfire.

Inside the General setting is where you can edit your title and add a description for your Well Log visualization. There are also options to "Show title bar" in the Well Log Visualization.

# Data

Data table - Choose a Well Log Data table
Marking - Choose to set a Marking
Limit Data by Marking - Choose to Limit by Marking (only ,arked selection will populate the Well Log)
Limit data using Filtering - Choose to set filtering scheme from Spotfire
Limit Data using expression - Create a custom expression to limit the data.

# Curve Data

Trellis by - Choose a column group to trellis by
Well Label Column - These are the label titles on the RAI Well log Visualization.
Wells per Page - Limit the number of wells per page.
Depth Column - Depth Column from the data table.

Optional configuration if Data is pivoted is checked

Check the box "My data is pivoted"
Curve Name Column - Choose the curve column name.
Curve Value Column - Choose the curve value column.

# Appearance

The appearance menu has many different configurations, grouped into tabs.

# Fonts

Attribute	Description
Font	Change the Font on the Well log Visualization
Size	Change the Font Size on the Well Log Visualization.
Margin	Changes the Left Margin of the Well log Visualization.

# Focus

This is the line when hovering over the Well Log Visualization.

Attribute	Description
Line Width	Change the width of the line width
Line Color	Change the Color of the line
Ball Size	The size of the ball when hovering over the values of the Well Log.

# Legend

This is the legend underneath the Well Label Column |See picture below.

Attribute	Description
Legend Height	Change the Height of the legend
Checkbox	Enable or Disable Legend.

# Formation

Formations in the well log are used to show the locations of formation tops and bottoms through the depth axis of the well log chart.

# How to Configure Formation Tops

To add formation top data to the well log visualization:

In Well Log properties click Formations and check the box to Use Formations.
Under Data table, select the data table that contains depth, formation name, and well name data.
Set Limit data using marking, if applicable.
Set the Limit data using filterings to the filtering scheme for the tab.
Select the column that represents Depth, Formation name, and Well name in the data table previously selected.

# Layers

The well log layer configuration was designed to emulate the map chart visualization in Spotfire. Curves can be superimposed on top of tracks and managed like "layers". Begin by adding a track.

# How to add a Track

Click on (+) Add on the bottom left corner and click track.

# How to configure a Track

Select the track to be configured.
Edit the track options:

Track Title - Change the name of the track
Track width - adjust the size of the track.
Scale Type - Change the type of scale displayed on the track.

# How to add a Curve

Add a New Curve

Open the Well log properties
If no track exists, first add a track by clicking (+) Add > Track
If track exists, click on the track name
Click (+) Add > Curve to add a new curve in the selected track
Click on the New Curve
Go to the Configuration tab
Give the curve a name and select the column that contains the curve data
Go to Lines and Fill tabs to configure the settings for the curve

# How to configure a Curve

There are four tabs to edit: Configuration, Lines , Marker, and Fill. The configuration tab has fields for naming and describing the curve as well as setting the column that contains the curve you want to display on the track.

Lines The lines tab has settings for changing the line style, color, width, and interpolation for the selected curve. When left unchecked, the range of the curve is set to the min and max of the selected data set. Otherwise, **check the boxes for left (min value) and right (max value) **to set the range of the display for the selected curve.

Markers If you want to show markers check "Show Markers". This setting is similar to using a scatter plot with different marker icon.

There is a fill color option, stroke color, Max points, symbols, marker size.
To show all markers, check the "Show all markers"

Fill The fill tab has settings for coloring within the track. There are three modes: track, curve, and baseline:

Track mode sets filling of the selected color from one end of the track to the curve
Curve mode sets filling color beginning from the selected curve
Baseline mode colors the space between where the baseline is set to the curve. Make sure the baseline value is within the range for that curve.
