Oil Sands and the Environment – Part II

Introduction

Today I continue coverage of my recent visit to the Athabasca oil sands near Fort McMurray, Alberta. I was there as a guest of the Canadian government, which hosts annual tours for small groups of journalists and energy analysts. I will be covering multiple aspects of oil sands production in a series of posts.

In last week’s post — Oil Sands and the Environment – Part I — I discussed greenhouse gas emissions, impacts on wildlife, and I touched upon water usage. I also detailed some of the work of Pembina Institute (PI), which is working to improve the environmental conditions as the oil sands are developed. Today’s article will discuss the tailings ponds, water consumption, impacts to water quality, and impacts to indigenous people.

Tailings Ponds

There are two primary ways of extracting bitumen from the oil sands. In situ production involves injecting steam into the ground to heat up the bitumen which is then pumped out of the ground. Surface mining is done when the resource is fairly close to the surface. During my trip we visited one in situ producer – Cenovus Energy – and one surface miner – Canadian Natural Resources Limited (CNRL). These methods will be discussed in greater detail in next week’s post. CONTINUE»

Oil Sands and the Environment – Part I

Introduction

I spent the past week in the heart of the Athabasca oil sands in Fort McMurray, Alberta. I was there as a guest of the Canadian government, which hosts annual tours for small groups of journalists and energy analysts. During my trip I was told that the only person who ever asked as many questions as I did was when David Biello from Scientific American was a guest. (You can read one of David’s articles from his trip here).

I felt like I learned enough to write a book on the oil sands, so I have a great deal of information I want to share with readers in a series of articles. In these articles I will provide an overview of the oil sands, compare and contrast the different ways of processing them, discuss the environmental issues, and then discuss the particular companies that I visited on this trip — Cenovus Energy and Canadian Natural Resources Limited.

I want to start this series with a 2-part discussion on the environmental issues. Generally when people think of oil sands, the environmental issues are foremost on their mind. That has always been the case with me, so most of the questions I asked during my trip related to the impact of oil sands development on the environment. This is a very contentious issue, and one in which the battle lines have been drawn. CONTINUE»
