Logs Object

The Log object visualizes well logs. Multiple logged parameters may be visualized for multiple wells simultaneously. Log data are read from a Logs Dataset. Logs are shown as data series on a chart next to the well location.

NOTE: The “Refresh Data” button must be pressed to refresh the data from source. The “Apply” button will only affect the visual appearance. Data are refreshed automatically when adding new data series to the log chart.

Every time a log chart becomes visible a bitmap containing the chart is generated. This may cause that the navigation through the scene is not smooth.

Name: Object name as seen in the Object Manager
Visible: Show/Hide the object

Vertical Scale Mode
Depth: Left axis scale is zero at the top of the log and increases downwards with depth.
Elevation: Left axis scale is terrain elevation at the top of the log and decreases downwards with depth.

Resampling and Smoothing
Resample: Data will be re sampled using depth intervals. This will reduce the amount of data points and will improve performance and project save/load time. Data will be re sampled and averaged using the interval . The resulting value for each interval is simply the mean of the original data points within the mean interval (moving average).
Smooth: Data will be smoothed using depth intervals. In contrast to re sampling the amount of data points will not be reduced but will produce a smoother line. Data will be averaged using the interval. The resulting value for each interval is simply the mean of the original data points within the mean interval (moving average).

Vertical Axis Options
Depth Axis Title: Title for vertical axis showing depth.
Elevation Axis Title: Title for vertical axis showing elevation.
Show Secondary Axis: If left vertical axis is depth the optional right axis will be elevation. If left vertical axis is elevation the optional right axis will be Depth.

Fit To Surface
Active: When checked and a surface is selected in the “Available Surfaces” drop down all the logs are fitted to that surface. The fitting is purely visual - the data are not changed.
Available Surfaces: Available surfaces in the project that can be used for fitting.

Dataset: The Logs object visualizes a Logs Dataset.

The Geometry Tab contains settings for the chart shown in 3D. Press “3D Chart Data Setup…” To add log data series from the dataset to the chart.
3D Chart Data Setup…: Opens the Log Charts Editor.

3D Chart Settings
Center Offset: Log chart plane horizontal offset from the well location. If a well is visible at the same position as the log an offset is necessary to avoid overlap.
Width (scene units): Width of the chart plane in scene units, e.g. meters
Horiz. Bitmap Resolution (pixels): Horizontal resolution in pixels of the bitmap that shows the log.
Visible Distance: Beyond this distance logs are not visible. This distance should be short to improve performance.
Min. Turn Distance: Logs are not turned towards the camera when closer than this distance.

Material settings for 3D chart
Opacity: Degree of opacity. 1=fully opaque, 0=fully transparent (enabled when Blending Mode = Transparency).
Advanced: Shows the advanced Material Editor

The Print Tab contains printing settings. Press “Print Chart Data Setup…” To add log data series from the dataset to the chart and adjust printable report settings.
Report Setup And Print…: Opens the Log Charts Editor.

Same Maximum Depth For All Logs
Active: When checked all printed log charts will have the same vertical min and max scale on the vertical axis.
Common Depth: Common log depth.
