After the discussion in House Finance earlier today (04/29/06), we have received multiple requests for copies of the spreadsheets discussed. Attached are 9 different workbooks (in three files). There are 3 groups of 3 workbooks that go together.
The groups of workbooks that go together look at three field scenarios: Prudhoe Bay, Pt. Thomson, and a New Gas Field (think NPR-A or the Foothills of the Brooks Range).
Each one of those scenarios are run at different tax combinations on North Slope natural gas. The first is the formula adopted by the Senate 22.5 tax rate/25 credit rate and 1/3 of the wellhead value of the gas. The second set is the tax and credit rate adopted by the Senate, but with a 2/3 ratio on the wellhead value of the gas. The third set is the tax and credit rate introduced by the Governor, with a 2/3 ratio on the wellhead value of the gas.
The assumptions for capex/opex come from publicly available information for Prudhoe Bay and Pt. Thomson. The assumptions for the New Gas Field rely upon rule-of-thumb estimates in combination with information extracted from the Wood Makenzie GOGGR 2004 study.
