The Edit LAS Curve tool in the Well Correlation View allows users to apply basic processing and editing operations on individual log curves.
This is useful for cleaning, correcting, or customizing log data before interpretation or correlation.
To open the wizard click on a Top of the Well correlation view and choose Edit LAS Curve.
The wizard consists of the following key areas:
1. Well and Curve Selection
At the top, select the target Well and the Curve (log) you wish to edit using the dropdown menus.
2. Depth Range
Select the depth range over which the operation will be applied. Options include:
•MD range: Measured Depth
•TVD range: True Vertical Depth
•TVDSS range: the vertical depth measured below mean sea level
•Markers range: Use tops/markers to define interval
Enable and set:
•Start and/or End depth values to limit the editing range (optional).
3. Action – Log Editing Options
In this section, choose one of the available operations from the Action dropdown menu:
•Moving average filter: Smooths the log by averaging values within a specified window. Enter the window size in feet.
•Median filter: Reduces noise by replacing each value with the median of its surrounding values within the defined window.
•Bandpass filter: Applies frequency-based filtering to isolate or remove specific ranges in the data.
•Depth shift: Shifts the entire curve vertically by a fixed amount. Useful for aligning logs when depth mismatches occur (e.g., from tool calibration errors).
4. History Panel
The History tab on the right keeps track of all applied changes, showing a list of previous actions for easy reference or rollback (currently empty in the screenshot).
5. Buttons
•Apply: Applies the selected action to the curve but keeps the wizard open.
•Save: Applies changes, name the new curve and closes the window.
•Cancel: Discards all unsaved changes and closes the window.
