Comments on: Extraction technology drives rash of oil deals Mon, 26 Sep 2016 03:26:00 +0000 hourly 1 By: cswann Tue, 14 Dec 2010 20:43:36 +0000 Thanks for the comment Mr Henry. I can’t give a precise answer to your questions. The estimates I used in this article were from IHS, which is a consultancy.

How much of the remaining two thirds of hydrocarbons we can recover will partly depend on how hard we try. If you use hydraulic fracturing and horizontal drilling — along with a host of other methods — you may be able to prolong the life of even very mature oil wells. Companies like Apache have turned this into a speciality. If there are fewer discoveries of “easy” oil, this effort becomes more worthwhile. Also such technologies are getting better by the day. Who knos, we might be able to get another third out of the ground…. although that would really bake the planet.

Better energy efficiency would certainly extend the timeline.

Also there may still be new oil reserves that we have not yet uncovered.

Sorry these answers are not terribly specific. Hope that helps a bit.

How much more energy is now considered recoverable?

If the experts believe we have used no more than 1/3, how long until we run out?

Have any policies or conservation movements expanded the timeline?
