Canadian natural gas is important in a number of ways: It provides 17% of total US NG consumption and today contributes roughly 11% [see calc at bottom] of the energy content in a barrel of tar sands oil (which will only increase with in-situ recovery growth). By no means (conventional or unconventional), can Canada be considered to have lots of natural gas, yet, we produce more than our fair share. Accurately predicting Canadian NG supply is, of course, important for all the usual North American energy security reasons and, among others: It would be nice to know if Canadians will have NG for things other than tar sands and exports to the US. Half of all Canadian homes are heated primarily by natural gas and about 6% of Canada's electricity sector relies on natural gas, a lot of which is used as peak electricity generation.
It’s well known that Canadian conventional gas peaked around 2001, but according to a continuing trends prediction case from the National Energy Board, it doesn’t appear as if unconventional gas will be playing a big part, at least compared against 2001 peak production levels. Below I summarize some predictions for future production of Canadian natural gas and try to estimate how much of Canada's natural gas will be left over for regular Canadian citizens.

I recently visited BP America's tight gas facility in Wamsutter, Wyoming on a trip paid for by the American Petroleum Institute. I was the only representative of internet media on the trip. The other reporters on the trip were from AP-Cheyenne, Casper Star-Tribune, and Natural Gas Weekly. On the trip, we spent a day and a half listening to presentations and touring facilities. We also stayed overnight at the facility BP built for visiting workers.
In this post, I will tell a little about what I learned. I will also look at prospects for the future -- both in terms of being able to expand operations and threats to maintaining current production levels.
US natural gas production has been flat for a number of years. We keep hearing that US production is expected to begin declining sometime in the next few years, but it doesn't seem to happen. While it is not obvious from most published data, the reason production remains level is because unconventional gas production has been rising at the same time that conventional production has been declining. In this post, I will look at unconventional natural gas, since it plays such a pivotal role.
I hope you'll bear with me here. This is one of those really long posts I do from time to time to try to understand an important issue I didn't know much about. I even try here and there to emulate HO's "techie talk" tradition here on TOD though with, I'm sure, limited success.
Liquified natural gas (aka LNG) involves cooling the gas to minus 160 degrees (Celsius). That shrinks it to about 1/600th of its original volume, allowing significant quantities of this LNG to be loaded aboard tankers for shipment overseas. When the gas reaches its destination at an LNG terminal, the gas is reheated (regasification) and shipped through pipelines to end users.
