The Alberta Energy Regulator (AER) provides monthly data for oil production in Alberta, including from the oil sands region in a report known as the ST-3. The data are available here, and you can either download the data and analyze it yourself or use the embedded R code below to download all the data.

This page is also an easy introduction for downloading and manipulating data in R. If you’re going to run the R code, you’ll need a few basic set-up elements to get everything to work. I’ve included the code here for your reference.

Download the Data

Once you’ve got the preliminaries of the code, downloading the data is fairly easy. Each of the data files are stored by year, with the exception of the current year which has a different naming convention. The first step is to access the data (click on the code button to see how to do things in R if you’re interested). The code also includes some fixes for names of projects which are not consistent in the data. This is basically a trial and error process to find broken data series.

#I'm going to make a function here so that I can specify whether I want to download all/none/new
