CALGARY, ALBERTA--(Marketwire - Sept. 5, 2012) - Donnybrook Energy Inc. ("Donnybrook" or the "Company") (TSX VENTURE:DEI) reports that production tubing string has now been installed in the DEI Bigstone Hz 13-33-60-22 W5M Montney well (DEI 25%) and that the well is now ready for tie-in to the Company operated Bigstone pipeline system. Construction of surface facilities and 1,300 metres pipeline installation is anticipated to commence in mid October with an estimated on-stream date of early November 2012.

The well was flowed back after installation of the tubing string. The average flow rate during the final 24 hours of a limited flow back production test period totaling 32 hours and 15 minutes, was 2.87 mmcf/day (DEI net 0.72 mmcf/d) and 510 bbls/day (DEI net 128 bbls/day) of condensate and load fluid. Approximately 75% of the load fluid used during fracing operations has been recovered to date. The 13-33 well was drilled to a total measured depth of 5,336 metres with a lateral length of approximately 2,600 metres and completed with a 23 stage frac.

At Bigstone, Donnybrook has 8 gross sections (2,048 ha) 3.75 net sections (960 ha) of P&NG rights located approximately 35 kilometres (22 miles) east of the eastern edge of the Company's Simonette acreage block.

Donnybrook holds interests in 46 gross (22.9 net) sections of petroleum and natural gas rights in the Bigstone-Simonette-Resthaven liquid rich natural gas resource play in the Deep Basin area of west central Alberta.

This press release contains forward-looking statements or information ("forward-looking statements") within the meaning of applicable securities laws including statements regarding the timing of the construction and completion of the surface facilities and pipeline installation for the Bigstone 13-33 well. The use of any of the words "will", "expects", "believe", "plans", "potential" and similar expressions are intended to identify forward-looking statements.

The forward-looking statements in this press release are based on certain key expectations and assumptions made by Donnybrook, including the quality of the Montney reservoir, continued performance from existing wells, future drilling programs and performance from new wells, the growth of infrastructure, well density per section, recovery factors and that development necessarily involves known and unknown risks and uncertainties. Although Donnybrook believes that the expectations and assumptions on which such forward-looking statements are based are reasonable, undue reliance should not be placed on the forward-looking statements because Donnybrook can give no assurance that they will prove to be correct. There is no certainty that Donnybrook will achieve commercially viable production from its undeveloped lands and prospects.

Since forward-looking statements address future events and conditions, by their very nature, they involve inherent risks and uncertainties. Actual results could differ materially from those currently anticipated due to a number of factors and risks. These include, but are not limited to the risks associated with the oil and gas industry in general such as: operational risks in development, exploration and production; delays or changes in plans with respect to exploration or development projects or capital expenditures; the uncertainty of reserve estimates; the uncertainty of estimates and projections relating to reserve, production, costs and expenses; health, safety and environmental risks; commodity price and exchange rate fluctuations; marketing and transportation of petroleum and natural gas and loss of markets; environmental risks; competition; incorrect assessment of the value of acquisitions; failure to realize the anticipated benefits of acquisitions; ability to access sufficient capital from internal and external sources; stock market volatility; and changes in legislation, including but not limited to tax laws, royalty rates and environmental regulations. Readers are cautioned: (i) the foregoing list of factors is not exhaustive; and (ii) not to place undue reliance on forward-looking statements. Additional information on these and other factors that could affect the operations or financial results of Donnybrook are included in Donnybrook's Annual Information Form, management's discussion and analysis and other documents filed with applicable securities regulatory authorities and may be accessed through the SEDAR website ( The forward-looking statements contained in this press release are made as of the date hereof and Donnybrook undertakes no obligation to update publicly or revise any forward-looking statements, whether as a result of new information, future events or otherwise, unless so required by applicable securities laws. The forward-looking statements contained in this press release are expressly qualified by this cautionary statement.

Where amounts are expressed on a barrel of oil equivalent ("BOE") basis, natural gas volumes have been converted to oil equivalence at six thousand cubic feet per barrel. The term BOE may be misleading, particularly if used in isolation. A BOE conversion ratio of six thousand cubic feet per barrel is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead. References to oil in this discussion include crude oil and natural gas liquids ("NGLs"). NGLs include condensate, propane, butane and ethane. References to gas in this discussion include natural gas.

The reader is cautioned that the well test results disclosed in this press release are not necessarily indicative of long-term performance or of ultimate recovery.
