Schedule of Proved Developed and Undeveloped Oil and Gas Reserve Quantities [Table Text Block] |  | The changes in the Company's estimated quantities of proved natural gas and oil reserves for the year ended December 31, 2011, were as follows:
| Natural Gas (MMcf) |  |  | Oil (MBbls) |  |  | Total (MMcfe) |
Proved developed and undeveloped reserves: |  |  |  |  |
Balance at beginning of year | 448,397 |  |  | 32,867 |  |  | 645,596 |
Production | (45,598 | ) |  | (3,500 | ) |  | (66,596 | )

Balance at end of year | 379,827 |  |  | 34,347 |  |  | 585,908 |
Significant changes in proved reserves for the year ended December 31, 2011, include:
• | Extensions and discoveries of 65.0 Bcfe primarily due to drilling activity at the Company's Bakken and Big Horn properties
• | Revisions of previous estimates of (59.6) Bcfe, largely the result of a reduction in PUD reserves of 53.6 Bcfe resulting principally in the Company's Bowdoin, Baker, Coalbed, East Texas and Big Horn Basin properties. The remaining negative revisions were a reduction in PDP natural gas reserves.
The changes in the Company's estimated quantities of proved natural gas and oil reserves for the year ended December 31, 2010, were as follows:
| Natural Gas (MMcf) |  |  | Oil (MBbls) |  |  | Total (MMcfe) |
Proved developed and undeveloped reserves: |  |  |  |  |
Balance at beginning of year | 448,425 |  |  | 34,216 |  |  | 653,724 |

Balance at end of year | 448,397 |  |  | 32,867 |  |  | 645,596 |
Significant changes in proved reserves for the year ended December 31, 2010, include:
• | Extensions and discoveries of 56.5 Bcfe primarily due to drilling activity at the Company's Bakken, Baker, Bowdoin and east Texas properties
• | Purchases of proved reserves of 61.0 Bcfe as a result of the Company's acquisition of natural gas properties in the Green River Basin in Wyoming, as discussed in Note 2
• | Revisions of previous estimates of (55.5) Bcfe largely the result of negative performance revisions resulting primarily from new information gained from production history and developmental drilling activity in the Company's Bowdoin, south Texas, Baker and east Texas properties and removal of PUD reserves due to the five-year limitation rule, partially offset by positive revisions due to increased natural gas and oil prices
The changes in the Company's estimated quantities of proved natural gas and oil reserves for the year ended December 31, 2009, were as follows:
| Natural Gas (MMcf) |  |  | Oil (MBbls) |  |  | Total (MMcfe) |

Balance at end of year | 448,425 |  |  | 34,216 |  |  | 653,724 |
Significant changes in proved reserves for the year ended December 31, 2009, include:
• | Extensions and discoveries of 42.3 Bcfe primarily due to drilling activity at the Company's Bowdoin, Bakken, Baker and east Texas properties
• | Revisions of previous estimates of (122.1) Bcfe largely the result of negative revisions resulting from decreased natural gas and oil prices and negative performance revisions resulting primarily from new information gained from production history and developmental drilling activity in the Company's east Texas and south Texas properties
