Welcome to Danomics: 3D Property Modelling

Getting Started with 3D Property Modelling in Danomics

This series of tutorial videos covers how to generate 3D property models of your reservoir in Danomics. You should have already reviewed the geoscience and petrophysics tutorials prior to starting this series. We will walk your through the process step-by-step, but it operates on the assumption that you are already familiar with those tools.

To execute on all of the steps in this tutorial you will need a geoscience, petrophysics, and property modeling license.

Note: For those whoe have not yet done the petrophysical interpretation or wish to match our interpretation exactly, on Step 6 there will be a second video and a download link for an already interpreted log database that you can use.

Sample Data

For this tutorial you will need well log, well header, shape file, and deviation survey data. You can download them using these links:

• Well log data
• Well header data
• Formation tops data
• Production data (CSV format / Excel format)
• Wyoming Counties Shapefile and Projection
• Wyoming Townships Shapefile and Projection
• Deviation Surveys

Step 1: Loading Data

To get started you will first need to upload some data to Danomics. In the video below we show how to upload well log, well header, well tops, production, and shapefile data.

Step 2: Setting the Projection

Setting the projection is crucially important when starting a 3D modelling project. This video shows how to set that at the project (folder) level.

Step 3: Adding Deviation Surveys

Now we add deviation surveys and process them for use in Danomics. This is a pre-requisitive if you will be using any tops from deviated wells in your structure gridding.

Step 4: Creating a New Map

In this video we create a new map that will be the future home of many of the displays we will be building in this video series.

Step 5: Generating Structure Grids

We are now ready to make structure grids using our TopsToStructureGrid Flow tool. We will then display the grids in a map, 3D view, and 2D projection view.

Step 6: Incorporating Petrophysical Curves

Note! If youhaven't done a petrophysical interpretation or want to use the same well log data we are using download this data:

• Interpreted LAS Data
• Skip to the second video in this sectionI demonstrate how to load it.

This video demonstrates how to write the results from a CPI to a log database using a Flow.

In this video I directly import the well logs (using the data provided above).

Step 7: Making the 3D Property Volume

We have now arrived at our destination - in this video we'll make the 3D Property Volumes using Flows.

Step 8: Adding the 3D Model to a Map

Now we will add the 3D Volume to the map that we created earlier.

Step 9: Adding Well Logs to the View

We'll now make our display more insightful by adding well logs to our 3D view alongside the model.

Step 10: Extracting Data into New Wells

Now that we have the model we can use it to do all sorts of interesting operations. One workflow is to extract data from the models into wellbores that we have deviation surveys for, but no log data. This could be especially useful if you want to know the expected signature of an undrilled well.

Summary

Congratulations on completing the 3D Property Modelling Welcome Tutuorial in Danomics. Although there is significantly more functionality available, the knowledge taken from the videos above should provide you with the fundamentals needed to work through any project in Danomics.
