Calvalley Petroleum Inc. (TSX: CVI.A)

CALGARY, Feb. 22 /CNW/ - Calvalley Petroleum Inc. (Calvalley), is pleased to announce that its Board of Directors has accepted the 2010 Year End Reserves Report (Report), prepared by McDaniel and Associates Consultants Ltd. (McDaniel), that evaluated Calvalley's oil and gas reserves at December 31, 2010.

Calvalley is an international oil and gas company, with offices in Calgary, Alberta, Canada, that operates its 50% working interest in Block 9 of the Masila Basin, in The Republic of Yemen. Calvalley also operates its 100% working interest in the Gimbi and Metema Blocks of the Blue Nile Basin, in The Republic of Ethiopia.  McDaniel is an independent petroleum reservoir engineering consultant firm, with offices in Calgary, Alberta, Canada.


  • Proved Reserves (1P) - Calvalley's 1P reserves increased 31%, to 15.6 million barrels of oil (MMBbl), over the quantities estimated by McDaniel at December 31, 2009. This increase in 1P reserves represents a production replacement of 544 percent.
  • Proved plus Probable Reserves (2P) - Calvalley's 2P reserves increased 20%, to 31.8 MMbbl of oil, over the quantities estimated by McDaniel at December 31, 2009. This increase in 2P reserves represents a production replacement of 740 percent.
  • Proved and Probable plus Possible Reserves (3P) - Calvalley's 3P reserves increased 21%, to 47.6 MMbbl of oil, over the quantities estimated by McDaniel at December 31, 2009. This increase in 3P reserves represents a production replacement of 1,082 percent.

Contributing factors in the reserves increases were the test results of the Ras Nowmah-2 well and an improved recovery factor as a results of recently implemented water and gas injection for the Hiswah Field. Other contributors were additional successful development wells at the Hiswah and Al Roidhat Fields. 


Calvalley continues to achieve one of the best capital efficiency performances in the E&P sector. In 2010, the company drilled five (5) development wells in the Hiswah Field, one (1) development well in the Al Roidhat Field, and one (1) appraisal well at Ras Nowmah. Calvalley also commenced drilling of the Qarn Qaymah-3 appraisal well which is expected to be reach target depth within the next week. Finding and Development (F&D) costs have been as follows:

  • In 2010, F&D costs were $3.22 (1P) and $0.64 (2P).
  • On a three year average basis, F&D costs were $5.14 (1P) and $2.20 (2P).

Based on McDaniel's Report forecast, Calvalley's share of future development costs for Block 9 will be as follow:

$MM (US Dollars)
  2009 2010
1P         51.6         47.7
2P        99.3        84.9
3P      159.0      147.7


All estimates of net cash flow are stated after current and estimated costs of Calvalley's  technical team, after all general and administrative costs in Yemen and after Yemen Government's share of production including royalties and profit oil.

The estimated future net present values at 2010 Year End, presented below, are calculated using McDaniel's forecast of future Brent Crude prices, at December 31, 2010.
