Example Flow: Processing Deviation Surveys
This Flow covers how to use a Flow to process your deviation surveys. The Flow uses the following tools:
- PointsInput >> Brings the deviation surveys data into the Flow
- DeviationsToXYZ >> Processes the deviations
- PointsOutput >> Writes the flow to a new points database
The PointsInput is where you select your import deviations survey. You should import deviation surveys in a format similar to what is shown here with columns for API, MD, Inclination, and Azimuth.
The DeviationsToXYZ tool puts the deviations into the format Danomics uses internally for all displays, mapping, and gridding operations. All you need to do in this tools is ensure your column names match the options. PointsOutput will write the result, which will look like the following.
Tips and Tricks
- Make sure to process your deviations before you do any of the other gridding flows the require deviations or before using them in a petrophysics project.
- Make sure that the input / output have distinct names!

DCA: Type well curves
In this video I demonstrate how to generate a well set filtered by a number of criteria and generate a multi-well type curve. Before starting this video you should already know how to load your data and create a DCA project. If not, please review those videos. Type well curves are generated by creating a decline that represents data from multiple wells.
DCA: Loading Production data
In this video I demonstrate how to load production and well header data for use in a decline curve analysis project. The first step is to gather your data. You’ll need: Production data – this can be in CSV, Excel, or IHS 298 formats. For spreadsheet formats you’ll need columns for API, Date, Oil, Gas, Water (optional), and days of production for that period (optional). Well header data – this can be in CSV, Excel, or IHS 297 formats.
