To visualize the province I made a section plot of the structures at every township in Alberta. Data is from the Atlas of the Western Canadian Sedimentary Basin Well Control Data. Note that there are some errors in this (some data is in twice), due to the way the AWCSB has the data, I will have to revisit it, and correct it at a later date. The process for getting the data to plot was:


  • Average the depths to the structures for every section, from all the wells in the atlas.

  • Move through the province south to north one township at a time, and plot the depths of the structure tops


Fairly simple, good process for a computer to do. I am pleased with the results. The labels are located at the structure tops. If there was no depth data for that structure in the section, the program would default the depth to 200m or the average from the most recent township. This is not specifically flagged, so there could be some data quality issues there.

An example image is here.
You can see the full result here.

Also, made a 3D model in blender.

Some other cool ideas would be contour maps of each structure, or switching and using the isopach values, rather than structure tops. Either way very cool dataset!

NOTE: Any info about the power grid from here and older is out of date :). Lot’s has changed since this was written.
To illustrate how the price is determined, it is most simple to use a line graph of the cumulative sum of bids, and the price they are bid in at. This illustrates that in order for the price to go up alot, all the easy sources of power must be exhausted. Currently there are lots of low cost sources of power in Alberta.

In the remainder of this post, I will explain how that is generated.

Recently I have been looking into making heat maps of options prices/open interest at different strike prices and expiry dates. I have automated the process and have a site here where the heat maps can be viewed.

Just made another flow calculator which takes as inputs the gas composition. It uses that information to calculate the gas density, ratio of specific heats, and uses the Redlich Kwong equation of state to calculate the compressibility factors. The compressibility factors are not bang on, I could switch to the redlich-kwong-soave equation later, comparing to the AER Directive 17 test cases, it is not always within the +/- 0.25% required, but it is close. You can access the flow calculator here. Expect to see an app coming out which replicates this functionality.

Just made an interface to see the structure top values in the Western Canada Sedimentary Basin from actual well data. All the wells are plotted on a map, you can click on a point to view the data from it. You can keep adding the points to view them side by side. You can access the interface here. The data is from here. Currently it is just the top values data sets, which would probably be the most useful for finding traps, and coming up with a stratigraphic section. It appears the data sets do not contain very old wells, but there are still alot (16086), so I apologize in advance if the interface is a little slow. I will optimize it later if it ever becomes very popular.
