Donnybrook Energy Inc.: Deep Basin Operations Update

CALGARY, ALBERTA--(Marketwire - April 13, 2011) - Malcolm Todd, Chief Executive Officer of Donnybrook Energy Inc. ("Donnybrook" or the "Company") (TSX VENTURE:DEI) reports that it has successfully completed the Donnybrook operated 13-27-61-02 W6M (70% working interest) horizontal Montney location at Resthaven, Alberta with a 12-stage fracture stimulation program. The 13-27 well, which is located approximately four miles northeast of Celtic Exploration's 02-07 discovery well, was flowed up seven inch casing at rates of up to 3.25 MMCF per day of natural gas on frac clean-up.

The frac clean-up was suspended and the well has been shut-in due to the on-set of spring break-up. During the abbreviated frac clean-up, the well had only recovered 30% (1,900 m³ of the 6,500 m³) of the frac fluid. In light of information received to date, Donnybrook and its partner, Celtic Exploration (30%) will proceed with tie-ing in the well as soon as conditions permit. The tie-in point is located within 200 metres of the 13-27 wellhead. Once the well is tied-in, the frac clean-up will resume to recover the balance of the frac fluid and the well will be flow tested in-line to determine an estimated flow rate and liquids (oil and NGLs) content, which is expected to be approximately 50 barrels per MMCF.

At Resthaven, Donnybrook has 5 gross (2.66 net) sections of Triassic Montney P&NG rights located five miles west of the western edge of the Company's Simonette acreage block.

Bigstone, Alberta

At Bigstone, Donnybrook as operator, plans to spud a horizontal Montney well (25% BPO/50% APO) in July 2011. The well is located within five miles of a recently announced liquids rich natural gas well drilled by an industry partner. After clean-up, the well reportedly flowed on test over the last day at an average rate of 13.1 MMCF per day of natural gas, with an expected liquids (oil and NGLs) yield of approximately 50 barrels per MMCF. Donnybrook holds a 100% working interest in 9 sections of Triassic Montney P&NG rights at Bigstone.

Simonette, Alberta

At Simonette, Donnybrook will be participating as to a 50% working interest in a horizontal Montney well, operated by Cequence Energy, in July 2011. Donnybrook plans to drill two additional horizontal Montney locations on its 38 section (22 sections net) Simonette acreage block prior to year end.

Donnybrook has working interests in 58 gross sections (42 net sections) prospective for Montney, Bluesky, Wilrich and Falher liquid rich resource development in the Deep Basin providing a potential current inventory of 168 net drilling locations.

The Company reports that it has filed its financial statements and management's discussion and analysis for the year ended December 31, 2010 on SEDAR and which can be viewed under Donnybrook's profile at www.sedar.com. Copies of information can also be obtained by contacting the Company.
