TAG Oil's Sidewinder-2 Discovery Well Flows at 1467 Barrels of Oil Equivalent Per Day

VANCOUVER, June 23, 2011 /CNW/ - TAG Oil Ltd. (TSX-V: TAO) and (OTCQX: TAOIF) is pleased to report that a 4-Point Isochronal flow test was completed over the main discovery zone in the Sidewinder-2 discovery well, which achieved stabilized flow rates of 8.8 million cubic feet per day (~1467 BOE per day) with less than a 25% drawdown.

The results from Sidewinder-2 further strengthen the already robust project economics, with anticipated full-time commercial production commencing upon completion of the new Sidewinder production facilities in a few months time. The Sidewinder-2 well is the fourth Sidewinder well that has been flow tested, all of which have achieved excellent flow rates, as summarized below:

Sidewinder-1 7.40 1,233 28% 14 Meters
Sidewinder-2 8.80 1,467 25% 47 Meters
Sidewinder-3 7.21 1,202 40% 15.4 Meters
Sidewinder-4 6.98 1,163 25% 19 Meters
Totals: 30.39 mmcf/day 5,065 BOE/day  

The Sidewinder-2 exploration well was drilled to a depth of 1,597 meters (5,238 feet), intersecting the main Sidewinder discovery zone, as well as four other separate oil-and-gas charged zones of interest totaling 47 meters (157 feet) of net pay. The interpreted pay zones are primarily within the Miocene-aged Mt. Messenger Formation; however oil shows were also encountered in the shallower Urenui Formation.

The Sidewinder oil and gas discoveries are located in TAG Oil's Petroleum Exploration Permit 38748 (TAG 100%) in the Taranaki Basin, New Zealand, with further exploration drilling in the lightly-explored area scheduled to recommence in September 2011. TAG will continue to target the widespread high-impact prospects identified in the Mt. Messenger Formation.

Cheal-C1 Oil Discovery Flow Testing to Begin

Following final completion of the Sidewinder-2 testing program, TAG Oil will begin flow testing the Cheal-C1 oil discovery located in TAG's Cheal oil and gas field, also in the Taranaki Basin. As reported in the Company's June 6, 2011 Press Release, the Cheal-C1 exploration well encountered 15 meters (49 feet) of net oil-and-gas bearing sandstones within the Mt. Messenger Formation, which significantly extends the known oil saturation area in the Cheal permit area. The Cheal-C1 well also encountered oil and gas shows within a 73-meter-thick section of sandstone within the deeper Moki Formation target.

TAG Oil Ltd.

TAG Oil Ltd. (http://www.tagoil.com/) is a Canadian-based production and exploration company with operations focused exclusively in New Zealand. With 100% control over all its core assets, including oil and gas production infrastructure, TAG is anticipating substantial oil and gas production and reserve growth through development of several light oil and gas discoveries. TAG is also actively drilling high-impact exploration prospects identified across 2,712 sections of land in the onshore Taranaki and East Coast Basins of New Zealand's North Island.

In the East Coast Basin, TAG Oil is pursuing the significant unconventional resource potential estimated in the fractured shale source-rock formations that are widespread over the Company's acreage. These oil-rich and naturally fractured formations have many similarities to North America's Bakken Shale source-rock formation in the successful Williston Basin.

"BOE"s may be misleading, particularly if used in isolation. A BOE conversion ratio of 6Mcf: 1 Bbl is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead.
