“Would you point out what you considered a federal subsidy for oil and natural gas?”
http://www.awea.org/learnabout/publications/upload/Subsidies-Factsheet-May-2011.pdf
Percent Depletion Allowance - An oil and gas company purchases a lease for the mineral reserves, each year the produce minerals (oil/gas) the reserves get smaller, the value of the asset gets smaller. Just like ALL business that purchase an asset the depreciates in value, they get to claim that reduction in value. Eventually that asset has to be replaced of they are going out of business. At the same time, they had to pay taxes on the income of production. This is not an oil subsidy, it is treating an oil/gas industry as all other industries are treated.

Intangible Drilling Costs - All costs incurred in drilling a well other than equipment or leasehold. It is a cost of doing business and like all business, they get to deduct costs. They pay taxes on profit, not revenue, just like all business.

Let me suggest a better source, and one not biased against the oil/gas industry as the publication from the American Wind Energy Association might be considered.
What’s an Oil Subsidy?
http://www.heritage.org/research/reports/2011/05/whats-an-oil-subsidy
At this link from Heritage Foundations shows, there are only three real items that can be considered subsidy. The first I agree should be eliminated. We don't need the Federal Government to conduct R&D; I don't believe the results are that helpful for actual increased production above that done by actual oil/gas companies.
The other two: Enhanced Oil Recovery (EOR) Tax Credit and Marginal Well Production Credit are both subsidies but have been effectively non-existent for quite some time. Respectively, they only go into effect at oil prices below $28 and $15 a barrel. Neither has existed for some time and have no effect today.
There is some argument to keep them for a possible short lasting time of such a price dip. It is in the national interest to keep up domestic production during a period of significant downturn, but they have no impact today.
So as the Heritage Foundation states, end real subsidies. But don't punish or reward select business by denying them the same tax rules that apply to other businesses.
By the way, as a source of comparison to the claims made by AWEA in the publication you linked, I would recommend reading:

I am definitely off topic with this post, but just offer it for related information.
