11. Unaudited Oil and Gas Reserves Information

 

As of March 31, 2012 and 2011, 100% and 91%, respectively, of the estimated oil and gas reserves presented herein were derived from reports prepared by independent petroleum engineering firm Ryder Scott Company.  For the year ended March 31, 2011, the remaining 9% of the reserve estimates, respectively, were prepared internally by the Company’s management.

 

Proved developed reserves are reserves expected to be recovered through existing wells with existing equipment and operating methods.  Proved undeveloped reserves are reserves expected to be recovered through wells yet to be completed.

 

Analysis of Changes in Proved Reserves.  Estimated quantities of proved developed reserves (all of which are located within the United States), as well as the changes in proved developed reserves during the periods indicated, are presented in the following tables:

  ¹ Revisions of Previous Estimates – Estimates reflect steady increases in oil and gas prices since December 2008, when prices reached a 5-year low.  Changes in performance constitute less than 10% of the total amount of revisions of previous estimates.

 

  ²

Extensions and Discoveries – 19 wells represent extensions and discoveries during the year ended March 31, 2012, all of which are located in North Dakota. Additions during the year ended March 31, 2011, consisted of eleven new wells – North Dakota (7), Montana (2), Colorado (1) and Texas (1).  Additions during the year ended March 31, 2010, pertained to 2 wells drilled in Colorado and 1 well drilled in North Dakota.

 

 

  ³ Production – Volumes of oil and gas that were produced were removed from reserves during the year.

 

The table below sets forth a standardized measure of the estimated discounted future net cash flows attributable to the Company’s proved oil and gas reserves. Estimated future cash inflows were computed by applying the 12 month average price of oil and gas on the first day of each month to the estimated future production of proved oil and gas reserves as of March 31, 2012, 2011, and 2010.  The future production and development costs represent the estimated future expenditures to be incurred in producing and developing the proved reserves, assuming continuation of existing economic conditions.  Discounting the annual net cash flows at 10% illustrates the impact of timing on these future cash flows.
