NGC To Acquire Kahili gas

Indo-Pacific Energy Ltd and NGC Holdings Ltd are considering the $NZ8 million development of the onshore Taranaki Kahili gas-condensate field in onshore Taranaki permit PEP 38736. The development will include pre-treatment facilities to separate and store condensate before injection of the untreated Kahili gas into the pipeline, and an 11 km export pipeline to deliver the gas from the Kahili-1B well site to NGC's existing Taranaki infrastructure. The project is likely to be commissioned by the end of 1st quarter 2004.

The field's sole producing well, Kahili-1B, was expected to produce approximately 5 PJ of gas and gas recovery could increase if the Kahili partners decided to drill additional wells in the future, NGC said.

Indo-Pacific Energy is the permit operator and holds a total 45% interest in PEP 38736 and the Kahili field, with Tap (New Zealand) Pty Ltd holding 30% and IRM (Malaysia) Inc 25%.

Tuihu-1A Re-entry In Onshore Taranaki Begins

Swift Energy New Zealand Ltd and partner New Zealand Oil & Gas Ltd, have begun re-entry and deepening of the Tuihu-1 well in onshore Taranaki in the PEP38718 permit, culminating in the side-tracking of the well (Tuihu-1A ) to a total depth of 5100 m.

Swift Energy is employing an underbalanced drilling technique designed to flow gas encountered while drilling, and optimise production flow rates in the event of a discovery.

Tuihu-1 was drilled in late 2000 - early 2001 to a total depth of 4530 m. Gas shows were encountered in what is now interpreted to be a fractured reservoir in the Tariki Sandstone. Tuihu-1 was suspended, pending further geological investigation. The primary targets for Tuihu-1A are reservoirs within the Tariki Sandstone and the Kapuni Formation.

Tuihu-1A is 6 km from the Tariki gas pipeline.

Participants in Tuihu- 1A are Swift Energy NZ Ltd 50%, NZOG 20%, Origin Energy Resources NZ Ltd 20%, and Indo-Pacific Energy Ltd 10%.

Discovery Geo Sinks Rahotu-1 Well Near Cape Egmont

Texas-based independent Discovery Geo (Australia) Corporation spudded the Rahotu-1 well in August in its PEP 38722 permit in onshore western Taranaki. The target depth of the well is approximately 3000 m.

Bernett Martin, President of Discovery Geo, said the well would seek targets in the Matemateaonga, Mt Messenger and Moki formations within a faulted horst feature. The company's previous exploratory well was the Warea-1 extension in May 2002, in a different area of the same permit.

Discovery Geo last year also acquired an onshore coastal permit PEP 38743 between Cape Egmont and New Plymouth and an offshore north Taranaki Basin permit (PEP 38479) south of Kawhia Harbour. New Zealand is now Discovery Geo's main exploration focus.

Discovery Geo, with a 12.5% interest, operates the Rahotu-1 permit with US partners Manti Resources Inc., Ultra Oil & Gas Inc., MM Cone Inc., and King Operating Corp.

Commission Approves Pohokura Joint Marketing

The Commerce Commission has authorised the Pohokura partners to jointly market and sell gas from their offshore Taranaki field.

The commission said it would allow the three competitors (Shell Exploration NZ Ltd, Todd Petroleum Mining Co. Ltd and OMV New Zealand Ltd) to work together to jointly market and sell gas produced from the Pohokura field, situated within permit PEP 38459.

However, the commission imposed three conditions:
• The partners only jointly market and sell gas after June 30, 2006 if the Pohokura field is fully operational.
• The commission authorises any subsequent sale of any interest in the field.
• The partners allow reselling of gas to third parties.

Commission acting chairperson Paula Rebstock said the decision to authorise the joint marketing arrangement reflected the fact that the development of some gas fields required a joint venture approach so gas from those fields could be brought to market as quickly as possible.

"The commission prefers separate marketing because competition is enhanced by more competitors. The purchasers of the gas may be able to negotiate lower prices, and better terms and conditions when they have a choice of supplier. Joint marketing lessens competition and represents a detriment to the economy."

However, the commission accepted that joint marketing should result in the earlier development of New Zealand's largest new gas field, and that early development had significant benefits to the New Zealand public.

Ms Rebstock cautioned other players against assuming any automatic approval of other joint marketing and selling proposals, saying this decision reflected the present state of the gas market. A statement by the Pohokura joint venture partners said that the attaching of significant conditions might delay development of the project.

However the largest partner, Shell New Zealand, also said the Commerce Commission's approval of the application to jointly market gas was a positive step towards delivery of the project. Shell New Zealand's Chairman, Lloyd Taylor, said that from a Shell perspective, Pohokura is still on track for first gas in 2006, despite the company's disappointment about the Commission's conditions attached to the joint marketing approval.

Indo-Pacific Begins Drilling Onshore Wawiri-1

In early September Indo-Pacific Energy (NZ) Limited and its partners commenced drilling Wawiri-1 well, the first of two back-to-back wells.

The Wawiri-1 well will investigate the hydrocarbon potential of a shallow tilted fault block. The primary target comprises sandstones of the Mt. Messenger Formation estimated to lie at a depth of about 1170 m. The well will be drilled to planned depth of 1400m.

Operator Indo-Pacific Energy holds a 30% equity in the permit with Australian-based companies Tap Oil and Magellan Petroleum each holding a 25% interest and Singapore-based Krystal Corporation Pte Ltd 20%.

Wawiri-1 will be followed by the Bluff-1 well, in PEP 38746, which is expected to be finished before the end of October.

Indo-Pacific Energy is also scheduled to continue its production test of the re-entered Cheal-1 well in onshore Taranaki licence PEP 38738 at the end of September. Chief executive Dave Bennett said the necessary separation equipment should be on site before the end of the month.

Indo-Pacific Energy Plans To Go Deep For Gas

Indo-Pacific Energy (NZ) Ltd is considering drilling some 'deep gas' wells in onshore Taranaki during the next two years.

Company Chief Executive, David Bennett, said that Indo-Pacific Energy's present exploration emphasis was on drilling the shallow Miocene-aged Mt Messenger prospects as it was easier to raise the capital necessary for these programmes, as well as the wells being easier and cheaper to drill than those targeting deeper formations. However, given the successful raising of exploration capital for deeper targets, it was possible Indo-Pacific Energy could drill up to three wells targeting such formations as the Tariki Sandstone or Eocene-aged Kapuni Group within the next two years. The Akama deep-gas feature identified by seismic in the PEP 38753 permit was a possible future target.

"The experience gained through participation in the current Tuihu- 1A re-entry well should be invaluable in planning and operating Indo-Pacific Energy's own deep gas drilling projects over the coming two years", Dr Bennett said.

Two Canterbury Basin Petroleum Exploration Permits Awarded

Two new offshore Canterbury Basin petroleum exploration permits have been awarded in the Government's latest permit tender round.

Two Australian explorers Tap (New Zealand) Pty Ltd and AWE New Zealand Pty Ltd have been awarded a 6647 km2 permit (PEP 38259) in the southern section of the basin off the Otago coast from north of Oamaru to Dunedin.

The 10,950 km2 predominantly offshore northern permit (PEP 38258), from south of Timaru to south of Christchurch, was awarded to a consortium of Indo-Pacific Energy (NZ) Ltd and Durum Energy (New Zealand) Ltd.

Announcing the new permits the Associate Minister of Energy, the Hon Harry Duynhoven, said, "The Canterbury Basin offers a real potential for a second petroleum producing province with an existing gas/liquids market and the potential for gas-fired electricity generation in the South Island." Tap and AWE have proven track records of finding and bringing to development major offshore hydrocarbon fields. Perth-based Tap (New Zealand) Pty Ltd holds interests in six onshore Taranaki permits. Sydney-based AWE New Zealand Pty Ltd, a wholly-owned subsidiary of Australian Worldwide Exploration Ltd holds interests in three Taranaki petroleum permits including the recent offshore Tui oil discovery.

Tap and AWE's work programme provides for the reprocessing of 1500 km of existing seismic data, reservoir characterisation and geochemical studies with special emphasis on the Galleon South and Barque prospects. A well is planned in the third year of the permit.

Indo-Pacific Energy has interests in 10 New Zealand exploration permits, one of these being the adjoining onshore Canterbury permit PEP 38256. Indo-Pacific Energy and Tap are partners in the recent Kahili onshore Taranaki gas-condensate discovery. Durum Energy, a subsidiary of Vancouver-based TAG Oil Ltd, is associated with Indo-Pacific Energy in two local exploration permits, one in onshore Canterbury and the other in offshore Taranaki.

Indo-Pacific Energy's work programme involves the compilation and evaluation of maturation and source rock data, the determination of a hydrocarbon charge model, basin modelling of oil expulsion efficiencies and migration modelling, reprocessing of 250 km of seismic data, remapping of stratigraphic and structural traps along the Clipper drilled sub-basin, with possible acquisition of 3D seismic data and a well drilled inside four years.
