TAG Oil Announces FY2018 Independent Reserves Results

VANCOUVER, June 19, 2018 /CNW/ - TAG Oil Ltd. (TSX: TAO and OTCQX: TAOIF) confirms that ERC Equipoise Ltd. ("ERCE"), a qualified reserves evaluator in accordance with National Instrument 51-101 and the Canadian Oil and Gas Evaluation Handbook, has completed its independent reserves assessment on the Company's producing oil and gas assets within the Cheal (PMP 38156), Cheal East (PEP 54877) and Sidewinder (PMP 53803) permits in New Zealand. This report is dated and is effective as at March 31, 2018.

ERCE has assigned a pre-tax net present value of $97 million (FY2017: $82 million), using a 10% discount rate to the Company's net working interest proven plus probable ("2P") reserves.

Reserves summary by field*

		%	Total Mboe	NPV10 $ mm	Total Mboe	NPV10 $ mm	Total Mboe	NPV10 $ mm

* The reserves and values are gross working interest and pre-tax.

Toby Pierce, CEO commented, "I am pleased with the reserves and resources that were added due to the waterflood program at the Cheal East permit. We continue to be encouraged by the potential increase in the overall field recoveries from the waterflood. I am also pleased with the increase in 2P NPV 10% after tax valuation to $96.1 million that was up from $78.3 million in the previous year despite the drop to US$68/b from US$70/b in ERCE's long term Brent oil price forecast year on year."

ERCE's gross 2P reserves estimates at March 31, 2018, were 4,079 Mboe (94% oil) compared to 4,143 Mboe (92% oil) gross 2P reserves reported by TAG Oil at March 31, 2017. The decrease in the Company's reserves of approximately 1.5% is attributable to the following factors:

• An approximate 8% decrease due to 351 Mboe produced over the 12-month period in fiscal year 2018.
  
  
• An approximate 7% increase in annual 2P reserves revisions of 287 Mboe, which is primarily due to technical revisions and reclassification from contingent resources:
  
  
• A significant reclassification from contingent resources to reserves was from the waterflood program at the Cheal East permit. Additional behind pipe pay opportunities have also been assigned reserves that were not previously included, such as the Cheal-B8 and E1 well re-completions in the Urenui formation.
  
  
• The technical volumes increased due to a revision on decline performance, which has improved in the Cheal-A3X, B6, B8, B10 and E2 wells, as well as the Sidewinder-1 and 2 wells.
  
  
• The technical volumes decreased due to revisions to the production profiles in the Cheal-BH1, B2 and B4ST wells. Also, the infill locations for the Cheal-BP and E9 wells were not included in this year's development, as well as the Cheal-A10ST and A7 workover, which have been replaced (Cheal-A10 workover and A7 conversion to injector) as part of the waterflood expansion.

All estimates and statements that describe the Company's plans relating to the Dividend and Coronado are forward-looking statements under applicable securities laws and necessarily involve risks and uncertainties. Actual results may vary materially from the information provided in this release, and there is no representation by TAG Oil that the actual results realized in the future will be the same in whole or in part as those presented herein.  

Other factors that could cause actual results to differ from those contained in the forward-looking statements are also set forth in filings that TAG Oil and its independent evaluator have made, including TAG Oil's most recently filed reports in Canada under National Instrument 51-101, which can be found under TAG Oil's SEDAR profile at www.sedar.com. TAG Oil undertakes no obligation, except as otherwise required by law, to update these forward-looking statements in the event that management's beliefs, estimates or opinions, or other factors change.

Disclosure provided herein in respect of boe (barrels of oil equivalent) may be misleading, particularly if used in isolation. A boe conversion ratio of 6 Mcf:1bbl is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead.

Reserves are estimated remaining quantities of oil and natural gas and related substances anticipated to be recoverable from known accumulations, as of a given date, based on analysis of drilling, geological, geophysical and engineering data, the use of established technology, and specified economic conditions, which are generally accepted as being reasonable, and shall be disclosed.

Reserves are classified according to the degree of certainty associated with the estimates. Proved reserves are those reserves that can be estimated with a high degree of certainty to be recoverable. It is likely that the actual remaining quantities recovered will exceed the estimated proved reserves. Probable reserves are those additional reserves that are less certain to be recovered than proved reserves. It is equally likely that the actual remaining quantities recovered will be greater or less than the sum of the estimated proved plus probable reserves. Possible reserves are those additional reserves that are less certain to be recovered than probable reserves. It is unlikely that the actual remaining quantities recovered will exceed the sum of the estimated proved plus probable plus possible reserves.

The qualitative certainty levels referred to in the definitions above are applicable to "individual reserves entities", which refers to the lowest level at which reserves calculations are performed, and to "reported reserves", which refers to the highest level sum of individual entity estimates for which reserves estimates are presented. Reported reserves should target the following levels of certainty under a specific set of economic conditions:

• at least a 90 percent probability that the quantities actually recovered will equal or exceed the estimated proved reserves;
• at least a 50 percent probability that the quantities actually recovered will equal or exceed the sum of the estimated proved plus probable reserves; and
• at least a 10 percent probability that the quantities actually recovered will equal or exceed the sum of the estimated proved plus probable plus possible reserves.

The reserve estimates contained herein are estimates only and there is no guarantee that the estimated reserves or resources will be recovered. The estimates of reserves for individual properties may not reflect the same confidence level as estimates of reserves for all properties, due to the effects of aggregation.

Where discussed herein "NPV 10%" represents the net present value (net of capital expenditures) of net income discounted at 10%, with net income reflecting the indicated oil, liquids and natural gas prices and initial production rate, less internal estimates of operating costs and royalties. It should not be assumed that the future net revenues estimated by TAG Oil's independent reserve evaluators represent the fair market value of the reserves, nor should it be assumed that TAG Oil's internally estimated value of its undeveloped land holdings or any estimates referred to herein from third parties represent the fair market value of the lands.
