Tracking TAG Oil’s production, development and infrastructure

Posted by Denise della Santina on Mar 8, 2012 7:52:00 AM

We put together a simple table to bring you up to speed on TAG’s Taranaki Basin oil and gas producing and drilling activity. The table includes producing oil and gas wells, wells in development (some awaiting workover operations as well as improvements in production infrastructure, to bring additional production that’s currently sitting behind pipe, on-stream), and our next condensate targets to be drilled. Status will change quickly, but here’s a snapshot of how TAG Oil's drilling and workover program stands now.

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.

Cheal Exploration drilling with a step-out well.

Posted by Kris Clark on May 16, 2011 12:18:00 AM

Exploration drilling is set to resume at Cheal; our next target is the Cheal-C1 exploration well, a 3.5-kilometer step-out well to the northwest of where we’re already producing light oil and gas. Cheal-C1 will test the Mt. Messenger (~1800m) and Urenui Formation sandstones (~1400m) ID’d on 3-D seismic and supported by strong bypassed oil and gas shows in the nearby deep Cardiff-1 well (~4000 meters) drilled by a previous operator back in 1995. Positive results from Cheal-C1 will lead to an immediate rig skid on the Cheal C site to drill the directional Cheal-C2 well targeting the same multiple formations located about 500 meters (1640 feet) northeast.

750 barrels a day…and that’s just the beginning.

TAG Oil PMP 38156 Cheal oil and gas field

TAG Oil’s PMP 38156 Cheal oil and gas field is producing about 750 barrels of oil equivalent a day…so far. That’s just 4 out of the 9 flowing wells, from the relatively shallow Mt. Messenger and Urenui Formations, with a lot more drilling operations and completion work still to go.

With proven and probable (2P) reserves presently assigned to only ~5% of the total Cheal Mining Permit acreage, the Cheal Mining Permit has some solid reserve and production growth potential. Especially if you look at how lightly explored the area is, and the number of perspective producer formations we still have to go at depths of 1400 to 4000 meters.

And owning our own oil and gas production infrastructure at Cheal allows TAG to control the timing of operations in case we want to fast-track any production arising from additional successes. There’s a lot of work ahead, but all in all it’s a good spot to be in.

Another light oil discovery at Cheal.

Cheal Formation Diagram
We put this cross section together illustrating the formations we’re intersecting, including Urenui, Mt. Messenger and Moki.

PEP 38156 (PMP 38156) came through. We drilled Cheal-B4ST to a total depth of 1810 meters, encountering 17 meters of net oil-bearing sandstones within the Urenui and Mt. Messenger Formations. Electric logs show great porosity and permeability, indicating four separate zones are likely to be oil-charged. Two of the four zones intersected are oil-bearing zones never before encountered in wells within this permit…demonstrating that the whole 7500-acre permit area is oil-prone, with multiple shallow horizons prospective for discovery.

Now it’s on to flow testing and the rest of the planned wells in our Taranaki Basin acreage.

Horizontal drilling in New Zealand…just days away.

 Horizontal drilling in New Zealand
The guys hard at work.

We’re releasing the drilling rig and mobilizing a service rig over to Cheal-BH-1 to complete our five-stage stimulation. Uphole mudlogs have recorded better than expected oil and gas shows in the secondary Urenui Formation, and in the Mt. Messenger horizontal section of the well, a total of 430m of continuous reservoir penetration is interpreted with high oil and gas readings.

All stage packers have been successfully deployed, and we’re going to have the first horizontal multi-stage fractured well in New Zealand in a matter of days.
