Cheal-B4ST exploration well gives us a strong flow test from multiple zones.

Posted by Kris Clark on May 31, 2011 12:09:00 AM

TAG Oil's Map of Taranaki Basin, New ZealandNews just how we like it: We drilled the Cheal-B4ST vertical exploration well to 1821m and encountered net pay in both the Urenui and Mt. Messenger Formations. Flow rates averaged 400 BOE per day (360 barrels of oil + 240 thousand cubic feet gas) after the first week of production.

The well encountered 17 meters of net pay within the Urenui at ~1400m and Mt. Messenger at ~1700m. These Miocene-aged zones were isolated and tested separately, confirming oil and gas flow rates from both. The Urenui test really opens a door on the potential reserve growth of the Cheal oil and gas field, which til now has relied on the Mt. Messenger formation only. The potential for PMP 38156 is just at the tip of the iceberg we hope.

TAG gets a substantial oil and gas reserve increase from Sproule.

Posted by Kris Clark on May 18, 2011 12:17:00 AM

Sproule International Limited, one of Canada’s largest independent petroleum engineering consulting companies, has released an assessment of TAG’s reserves in the Cheal Mining Permit and Sidewinder Exploration Permit increasing our probable reserve substantially.

After considering 2011 production, the 1,677,000 BOE in proved and probable reserves represents a 221% increase over their March 2010 reserve assessment.

Due to fiscal year-end 2011 cut-offs and the timing of April and May Sidewinder ops, the reserves relate primarily to the Cheal oil and gas field. Sidewinder’s reserve assessment was completed with information related only to the Sidewinder-1 well, and doesn’t (yet) include the now-completed Sidewinder-2, Sidewinder-3 and Sidewinder-4 wells. We think this just means more good news for the future.

The assessment of reserves has assigned net proved and probable reserves remaining of 1,360,000 barrels of oil (2010 = 651,000 bbls) and 1,864 mmcf of associated gas (2010 = 258 mmcf). This reserves report, on a 2P basis, amounts to 1,677,000 barrels of oil equivalent assessed in a reserves area covering just 475 acres of the 7,487-acre Cheal permit and just 107 acres of the 7,910-acre Sidewinder permit.

TAG Sidewinder gas pipeline gets welded.

Posted by Denise della Santina on May 12, 2011 4:59:00 PM

And some more Sidewinder gas pipeline photos are in from the field, these showing some of the welding process. The drizzle shouldn't slow things down, as TAG works to link its gas discovery with the North Island's main high-capacity pipeline.

Laying track: the Sidewinder gas pipeline is underway.

Posted by Denise della Santina on May 9, 2011 2:51:00 PM

Here we are building, on a great fall day, the pipeline that will link gas from TAG's Sidewinder oil and gas discovery into the Taranaki Basin's main high-capacity pipeline.

Sidewinder oil discovery flow test preparations.

Posted by Kris Clark on May 7, 2011 5:26:00 PM

Prepping to commence flow testing of Sidewinder-2, Sidewinder-3 and Sidewinder-4 wells in a few weeks’ time. And we keep cranking on the Sidewinder Production Station for its anticipated completion by mid-year.

Sidewinder-4…another oil and gas strike.

Posted by Kris Clark on May 6, 2011 5:16:00 PM
Sidewinder-2

Fortunately, this kind of news never gets old. The Mt. Messenger sandstones and PEP 38748 continue to pay off.

The interpreted total hydrocarbon column at TAG's Sidewinder discovery now exceeds 60 meters in thickness, with no water column evident in any of the Sidewinder wells.

The Sidewinder-4 well, sidetracked to a location down-dip of Sidewinder-3, targeted a fault-bounded 3-D anomaly which intercepted a gross 29 meter-thick sandstone reservoir. Total depth is 1410 meters with 19 meters of net oil-and-gas-charged sandstones; electric logs indicate hydrocarbon charge to the base of the sandstone. Free oil was observed over the shakers during the drilling operation from the target zone, and consistent with all of the Sidewinder wells drilled to date, the oil-and-gas-charged sandstones encountered in Sidewinder-4 have excellent porosity and permeability.

Third time’s a charm…Sidewinder oil and gas discovery does it again.

Sidewinder-3
The rig is a thing of beauty against heavy grey clouds.

PEP 38748 and Mt. Messenger do it again…the Company just announced that Sidewinder-3 is confirmed as a light oil and gas discovery. It’s been a busy couple of days: we drilled to 2160 meters about 1 km south of our Sidewinder-1 discovery, targeting a large anomaly ID’d on 3-D seismic. We encountered 15.4 meters of net oil-and-gas-bearing sandstones in the primary Sidewinder zone, including "free oil" observed over the shakers during the drilling operation.

With each new well we can more accurately calibrate our 3-D data set and better understand the geology of our acreage. In particular, Sidewinder-3 has shown that the Mt. Messenger Formation reservoir sands extend significantly to the south of the original Sidewinder discoveries, and hydrocarbons appear to have migrated into all potentially producing sands encountered to date. Good news for both near-term development and future exploration.

No time to rest on our laurels, it’s time to get busy on the Sidewinder-4 exploration well off to the east.

We’re on a roll.

Sidewinder-2
The guys are dirty but having a good time.

The sidetracked Sidewinder-2 well in PEP 38748 is confirmed as a multi-zone, light oil and gas discovery. We drilled to 1597 meters and hit 47 meters of net oil-and-gas-bearing sandstones, including "free oil" observed over the shakers during drilling…that means multiple potential pay zones. Electric log data shows excellent reservoir qualities, and better yet, even though this well has intersected and extended the main Sidewinder-1 discovery zone, we’ve also got five separate new oil-and-gas-charged pay zones, both above and below the primary target. Busy times ahead.

Sidewinder-2 began drilling today.

Posted by Kris Clark on Feb 7, 2011 4:35:00 PM

As we start drilling Sidewinder-2, we’re hoping to encounter results similar to Sidewinder-1. One well at a time; only time will tell for sure. But we have confidence in our seismic, our New Zealand field team and recent oil and gas discoveries.
