Welcome to Danomics

Thank you for using Danomics.  This short welcome guide walks you through uploading an example dataset, creating a new project, selecting a database and key well, provides an overview of how to set parameters, and generates a map in 5 easy steps.  This tutorial should take 15-20 minutes to complete. More extensive follow-up tutorials are available via the links at the bottom of this page and include a full petrophysical interpretation of the data, generating maps with shape file and production overlays, and many additional operations.

Sample Data

For this tutorial you will need well log, well header, and formation tops data. You can download them using these links:

The well log and well header were collected from the the State of Wyoming’s oil and gas commission website. The formation tops are a Danomics work product. Please note that we do not guarantee the completeness or accuracy of any of this data and recommend against using it outside of this demo.

Note that the interpretation performed below is for demonstration purposes only and omits a majority of the steps in the workflow.  The intent is to demonstrate only a few basic fundamentals.  For a more in depth interpretation that includes all of the modules, please see the links below or the Help Page.

Step 1: Uploading Data

In the File menu select File > Upload well headers… and then choose file well header data that you downloaded in the previous step.  In the Database name field provide a meaningful name. In this example, I named it “WelcomeProject.wdb”. Set the number of header rows to 1.  Click “OK”. Repeat the process to upload logs and upload tops as shown in the video below.

All of the files should upload and process in a few seconds and will then be visible in the file menu.

Step 2: Creating a New Project

In the File menu select File > New petrophysical calculation… and give it the name “WelcomeProject.cpi”.  Click “OK”. After clicking OK your new project will open. On the right hand side there underneath the word “Database” use the dropdown menus to select the files that you uploaded in the previous step. As you select the databases the well list and maps will be populated.  The map should automatically zoom to the extent of the data.  You can save by using Ctrl+S or File > Save.

Danomics will automatically alias and composite all of your curves under a common name, put all of your data in the same unit space, and standardize the refence lithologies when the data is loaded into a CPI file.

Step 3: Assigning a Key Well

Danomics uses the concept of a “key well”.  Parameters set in a key well will be used to build up an “interpretation blueprint” that will be automatically applied to non-key wells.  In this project we will use the Mykonos 1-36 as our key well (API: 49005291000000).  To set this as your key well, underneath the Database dropdown menus, click on the pencil icon and paste the API number into the text box.  Now in the well list you will see the well is now labelled “Key Well”.  In the map, if you click away from the key well you will see that it can be readily identified by a blue callout with a key icon.  Save by using Ctrl+S or File > Save.

Danomics has one-click curve normalization and automated, machine-learning powered badhole repair tools to make your data interpretation ready. These can be accessed in the Curve Normalization and Badhole ID and Repair module, but are not shown in this quickstart guide. For more information see their specific video tutorials on the help page.

Step 4: Interpreting a Property

Make sure the key well is selected.  Use the Module selection dropdown menu in the top middle of the screen to choose “Clay Volume”.  To optimize screen space use the double arrows in the Databases and Files areas to hide those menus. Click on the “Advanced” link in the parameters tab to expose all of the available methods and parameters.

Use the dropdown menu to set the “Lithology Presets” parameter and then use the crossplot to set the parameters for the Neutron-Density clay method.  The settings for the crossplot can be opened by clicking on the settings (gear) icon located on the top right of the crossplot window. The options in the setup will allow you to choose the formation(s) you wish to change parameters for. You may optionally filter the crossplot (for example, to eliminate badhole type “!@badhole”) and color the data (for example, to color by effective porosity type “@phie”).  The parameters can be modified by dragging and dropping the end-points.  This can be done for either a single zone or multiple zones at a time. To learn more about the filtering syntax see this help article and this article on crossplots.

Use the drag and drop parameter lines in the Gamma Ray track to set the GR Clean and GR Clay parameters.  Alternatively, you may type values into the parameter entry table.  The following approximate parameter values were used for this demonstration:

Note that you do not need to manually enter parameter values that match the “Default” parameter values entered.

Step 5: Setting Cutoffs and Making a Map

Make sure the key well is selected.  Use the Module selection dropdown menu in the top middle of the screen to choose “Cutoffs Interpretation”. Update the parameters by typing the desired cutoffs into the parameter entry box.  In this example the parameters entered were:

ZoneGross ResNet ResNet Pay
Default@vwcl <=0.40@phie >= 0.06 && @gross_res@sw <= 0.60 && @net_res
Niobrara@vwcl <=0.45@phie >= 0.06 && @gross_res@sw <= 0.60 && @net_res

Once the parameters are set activate the map tab and map the Net Reservoir property for the Niobrara.  To access the settings, click on the settings (gear) icon in the top right hand side of the map window. After ~2 minutes the map will have computed and will appear in the window.

Summary

You have now completed the Welcome Guide tutorial. Remember, this tutorial was not meant to cover every step, but only to show a few of the key fundamentals. For a full interpretation of the example please view the video below, which includes a full interpretation up through the volumetrics assessment. We will use the following additional datasets for this exercise:

The full interpretation is about 1 hour in length.
