Objective
The Editing Module enables users to perform granular edits on a well-by-well basis. Unlike other modules any changes made to the key well are not propagated to non-key wells. This module is also where all of the automated unit conversion, curve family conversions, lithology reference changes, and curve compositing is performed.
Key Parameters
- Shift scope: Specify if depth shifting should be performed and if so, if the shifting will be done curve-by-curve or file-by-file.
- Curve family: Select the group of curves to be operated on (e.g., GR, NPHI, or RHOB).
- Splice order: Specify if the default priority order for splicing should be changed.
- Filter scope: Specify if data should be filtered by curve attributes (e.g., only null all data where the curve value is above or below a threshold)
- Null depth ranges: Specify if data for a curve should be set to null over a specific depth interval(s).
- Curve shifts: Specify the amount of the depth shift. Only visible if Shift scope is not None.
- Scaling: Specify if the curves should be scaled.

Recommendations
- If multiple LAS files are present depth shifting (if needed) should most likely be performed on a File-by-file basis.
- Scaling should only be done to make curves internally consistent for that well. The Curve Normalization module is better suited to handle disparities between wells.
- If the same or similar changes need to be made across all wells, consider performing through an override of the CPI Config or via a Flow.
