Editing Module
Purpose
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.

Tips & Tricks
- 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.

Quick Start Module
Purpose The Quick Start module is designed to help users quickly set dozens of common parameters by selecting a handful of basic options from dropdown menus. Parameters There are three parameters that are set on a zone-by-zone basis and two parameters that are set on a full-well basis. These are as follows. Discussion The parameters are linked to what are called named_defaults in the software. These are collections of defaults that can be set through assigning a single parameter.

NMR Interpretation Module
Purpose The NMR interpretation module allows users to calculate porosity, bound and free fluids from the measure T1 and T2 distributions from NMR tools. Primary Outputs Discussion In oil and gas well logging, the $T_2$ distribution is used as a high-resolution "map" of the formation's pore system. While a standard porosity tool tells you how much fluid is there, NMR tells you where that fluid is trapped and whether it will flow.
