Deviations Surveys Module
Purpose
The Deviations module allows users to bring in processed deviation surveys into the CPI so that calculations for summaries can be done in TVD space. This affects summaries such as those for OOIP, OGIP, Net Pay, and more. Additionally it will help with consistency in calculations such as the temperature gradient when there are deviated wells.
Primary Outputs
The following curves are the primary interpretations made in this module.
| Curve Name | Description |
|---|---|
| TVD_OR_ALT_FT | True vertical depth curve |
| INCLINATION_FINAL | Wellbore inclination |
| AZIMUTH_FINAL | Wellbore azimuth |
Discussion
Deviation surveys are important when you have deviated wells in your petrophysical interpretation. Without importing deviation surveys it is assumed that your wells are vertical unless there are specific curves available for TVD, Inclination, and Azimuth in your LAS files. If all wells are vertical, or mostly vertical, deviation surveys can be considered optional.
Deviation surveys are imported as points and must be subsequently processed as shown in the video above using a Flow. This will ensure that the column names are all valid and present.

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.
Making Log Calculations in a Flow
This articles provides an overview of how to use a Flow to before basic log calculations. To do this, the following Flow tools are used: LogInput >> Bring the log data into the Flow LogMath >> Perform some calculation LogOutput >> Writes the log data to a new log database. There can be as many LogMath tools added to a flow as one would like, and they can be added to existing Flows ushc as a Log Clean-up Flow. The LogMath tool is extremely flexible.
